Explore The Power Of Computer Vision Technology & How It Is Changing The Way We See

A3Logics 19 Jun 2024

Human vision is more than just the capability to see. It’s also our ability to comprehend ideas abstractly and the experiences we’ve had from our many contacts with the outside world. In the past, computers were incapable of independent thought. But thanks to recent developments, computers can now see and process information. These are similar to humans thanks to
computer vision technology, a technique that imitates human vision.


Significant progress in computer vision has been made. This is because of the advances in artificial intelligence and computing power. Its role in daily life is growing. Estimates put the market size close to $41.11 billion by 2030 and a 16.0% compound annual growth rate (CAGR) between 2020 and 2030.


Machine learning methods and computer vision have emerged as a big technological advancement in recent years. Through several senses, computers get superhuman vision and are able to recognize patterns in images that humans are unable to. For instance, in the field of healthcare, computer vision surpasses human physicians in pattern recognition abilities.

According to research, radiologists are outperformed by artificial intelligence in diagnosing neurological illnesses using CT scan images. Computer vision solutions are emerging in a variety of industries thanks to vision artificial intelligence’s amazing exploits, and their future appears to be full of possibilities and unimaginable results.


What is Computer vision?


Computer vision is a branch of artificial intelligence. It trains computers and systems to recognize and understand meaningful information from digital photos, videos, and other visual inputs. When it detects flaws or problems, it can then recommend actions or take action. It does this by using machine learning and neural networks. Computer vision technology allows computers to see, observe, and comprehend, just as AI allows them to think. 


Except for human vision, computer vision functions very similarly to human vision. The benefit of human sight is that it has lifetimes of context to learn how to distinguish objects, measure their distance from one another, determine whether they are moving, and detect when an image is off.


Instead of using retinas, optic nerves, and a visual cortex, computer vision uses cameras, data, and algorithms to train robots to accomplish similar tasks in a fraction of the time. A system trained to inspect goods or monitor a manufacturing asset can quickly outperform a human in terms of analysis—it can examine thousands of products or processes in a minute and detect subtle flaws or problems.

How does computer vision work?


A lot of data is required for computer vision solutions. It repeatedly analyzes data to identify differences and, eventually, identify images. For instance, a computer must be fed a ton of tire photos and related objects to be trained to identify automotive tires. Only then will the computer be able to distinguish between tires and defect-free ones.


This can be done by two key technologies:


  • Convolutional neural networks (CNNs) 
  • Deep learning,a branch of machine learning.


Algorithmic models are used in machine learning solutions to allow a computer to educate itself on the context of visual input. When the model receives sufficient input, the computer will “look” at the data and learn to distinguish between images. Instead of requiring human programming to identify an image, algorithms allow the machine to learn on its own.


A CNN breaks images into pixels with labels or tags to aid in machine learning or deep learning models‘ “look.” It creates predictions about what it is “seeing” by performing convolutions—a mathematical procedure on two functions to produce a third function—using the labels. Until the predictions begin to materialize, the neural network performs convolutions and repeatedly evaluates the precision of its forecasts. The next step is for it to recognize or see images similarly to how humans do.


Similar to how a human sees an image from a distance, a CNN first detects simple shapes and hard edges before filling in the details as it makes more predictions. To comprehend individual images, a CNN is utilized. Similarly, recurrent neural networks (RNNs) are used in video applications to teach computers how images in a sequence of frames connect.

Types of computer vision

Computer Vision-Based Image Analysis


Using a variety of computational methods, useful information is extracted from images. This is then used for analysis using computer vision technology. It has numerous applications across a wide range of industries. These include healthcare, automotive, security, and entertainment, depending on this technology. The following summarizes the general process of picture analysis with computer vision technologies:


1. Preprocessing images


Images are frequently preprocessed before analysis to boost key features and improve quality for further processing. Typical preprocessing actions consist of:


  • Grayscale Conversion: By converting the image to grayscale, color processing is omitted, making analysis simpler.
  • Noise reduction: It involves applying filters to the image to smooth it out and cut down on any noise that can obstruct analysis.
  • Normalization: It is the process of uniformly adjusting the pixel intensity.
  • Edge detection: To improve the definition of borders and shapes, the image’s edges are highlighted.


2. Extraction of Features


The process of recognizing and separating an image’s different qualities or traits is known as feature extraction. Features could be particular patterns, colors, textures, or forms. A successful feature extraction process is essential since it directly affects the precision and effectiveness of the next stages of the analysis.

3. Segmentation


To simplify and transform the representation of an image into something more comprehensible, image segmentation splits a picture into many segments, or sets of pixels, also referred to as superpixels. There are various segmentation techniques:


  • Thresholding: Pixel separation according to a predetermined standard.
  • Segmenting: a picture based on predetermined criteria involves dividing it into areas.
  • Edge-based Segmentation: Identifying boundaries by detecting edges.
  • Clustering: is the process of assembling comparable pixels into groups.


4. Identification and Detection of Objects


In this step, items in an image are identified and categorized into predefined groups. There are several ways to accomplish this:

  • Template matching: This is the process of comparing portions of an image to a template to identify the existence of particular objects.
  • Machine Learning: Using AI picture recognition through the use of trained algorithms. This usually entails using a sizable collection of labeled photos to train a model.
  • Deep learning: It is the application of convolutional neural networks. These are capable of accurately and automatically identifying a range of objects in an image.


5. Interpretation and Analysis


Following item detection and classification, the system extracts insights by examining the surrounding context or, in the case of video, changes over time. This action could entail:

Finding patterns or abnormalities in an image is known as pattern recognition.

  • Compiling different statistics, such as size distributions or object counts, is known as statistical analysis.
  • Automated robotic process automation, for example, uses machine vision to interpret images and guide actions.


6. Decision Making


Making choices in light of the data analysis is the last stage. This might be as simple as sending out an alert when a specific object is found or as complex as offering medical imaging diagnostic information.

Challenges with Computer Vision


AI computer vision technology has a lot of promise. However, there are a lot of ethical and privacy issues regarding it. There are chances of misuse of a machine’s “seeing” and “understanding” capacity. This might cause privacy violations and other moral dilemmas.


Now, let’s look deeper into the details of these issues.


Privacy and Surveillance


One of the most serious problems using computer vision solutions in surveillance. With this technology, corporations and governments can watch people’s activities. This can potentially violate their privacy.

Consider China, where the use of computer vision is made for public surveillance.

Like the installation of more than 200 million surveillance cameras throughout the nation. Many of which use facial recognition software.


Although this contributes to maintaining public safety, it also poses issues with civil liberties and privacy. Privacy issues risks can increase even more when Computer Vision evolves further soon. Imagine this: a society in which all cameras—from traffic cameras to smartphones—can identify faces and follow your movements. Isn’t it some scary thought?


Prejudice and Disparities


Bias and discrimination are potential issues with computer vision and artificial intelligence. Large datasets are necessary to train AI systems, and biased datasets result in biased AI systems.


For example, a 2018 study by Microsoft and MIT discovered that darker-skinned and feminine faces had greater error rates for commercial facial recognition systems.


This is a result of the datasets’ predominance of male faces with lighter skin tones being used to train these systems. Discrimination may result from this prejudice in AI computer vision. For instance, a law enforcement agency using biased facial recognition software may make unjustified arrests or treat particular groups unfairly.


Future of Computer Vision


A few decades ago, the use of modern computer vision technology looked unattainable. Additionally, it appears that computer vision technology’s potential and capabilities have no limit in sight. What lies ahead for us to observe is as follows:


A greater variety of roles


With further investigation and improvement, computer vision technology will be able to do an increasing number of tasks. Because it will be simpler to train, the technology will be able to identify more images than it can currently. To develop more flexible applications, there will be a combination of computer vision with other technologies. For instance, visually impaired people can utilize natural language processing in conjunction with picture captioning software to comprehend objects in their environment.


Learning with little or no training data


The development of computer vision algorithms that require less annotated training data than present models is the key to the future of computer vision technologies. The industry has started looking into a few potentially ground-breaking research themes to overcome this challenge:


  • The process by which machines that are capable of manipulating their environment learn through a series of successes and failures in performing critical tasks such as grasping and navigating.
  • Artificial intelligence software that uses previously acquired visual concepts to learn new ones autonomously is referred to as lifelong learners.
  • The reinforcement learning approach takes its cues from behavioral psychology and focuses on teaching robots how to perform appropriately.


Common sense logic


Developing visual common sense knowledge and using it to respond to inquiries about pictures and videos is known as common sense reasoning. At this point, computer vision services can recognize and interpret several items in images.


Comprehension of what is captured in an image is merely the first step toward gaining a practical comprehension of digital image data. Acquiring and applying visual common sense reasoning is the next frontier for computer vision technology, allowing machines to do more than just recognize different kinds of objects in image data.


Anticipation of the computer vision sector says that it will develop interpretive computational models in the coming years. These models will be able to respond to the following queries about pictures and videos:


  • What’s present?
  • Who is in attendance?
  • What is the person doing?
  • What weather patterns are influencing their activity?


Additionally, computer vision solutions must be able to respond to increasingly complicated queries such as:

  • What is being done to whom and why?
  • What will probably happen next?


Robotics and computer vision combined


Robots in the real world will soon collaborate with computer vision technology. A significant potential over the next ten years is to create robot systems that can intelligently interact with people to support the achievement of particular goals.


Naturally, this has a lot to do with visual common sense. Recall that the goals and limitations of particular activities are illustrated through common sense reasoning. Therefore, by using common sense thinking to weigh the acts it observes an individual taking, a robot will be able to comprehend an individual’s goals. A computer vision model might see someone jogging in a metro station, for example. However, the robot will be able to determine if the person is trying to escape danger or catch the train with the use of common sense understanding.


The development of visual common sense will serve as an inspiration for the building of socially intelligent robots. Robot systems will be able to comprehend how human goals and duties motivate their activities as a result. These visual cognition-capable robots will be employed to improve situational awareness in various environments.


Acquiring knowledge without direct supervision


With a robot that actively investigates its environment, computer vision technology will undoubtedly improve thanks to technology. Robots of the future may be able to determine the class identities of the images they view. This implies that they won’t need any explicit manual labeling because they will be able to travel independently while following the objects to collect a large number of views on them.


One may question how can a robot accomplish it. Currently, computer vision solutions can determine an object’s class identity by exposing it to large amounts of training image data from a single object class in a passive manner. Hence, active interactions between the robot and the real environment will be useful to learn about the purported “affordances” of objects.


Affordances calculate an object’s possible applications. For instance, whether to open an object like a refrigerator, door, or soda can, or if it cannot be open, like a baseball or tree. Robots may accomplish goals in a variety of settings by learning the affordances of items.
