What Computer Vision Is and What It Gives Technology-Led Industries

computer vision

Computer vision is a subsection of artificial intelligence (AI) that is on the rise. Its focus is on developing and refining techniques that let machines see and understand digital images and video content.

Today we live in reality awash in visual information. According to HubSpot, 54% of consumers want their favorite brands to deliver more video content. Forbes suggests that websites, exposing a great deal of video content, make average users spend 88% more time on their pages.

To perceive visual information, we have a “superbly efficient tool” – our natural vision. The abilities of machines still lag far behind. By definition, computer vision mimics natural processes: retrieves visual information, handles it, and interprets results. And state-of-the-art algorithms, so-called artificial neural nets used for computer vision tasks, replicate natural neural networks.

What Are the Goals of Computer Vision?

Without having machines able to see, it will be difficult to teach machines to think. That is how Fei-Fei Li, from Stanford Vision Lab, describes the role of computer vision.

The difficulty is that computers see only digital representations of images. Humans can understand the semantic meaning of an image, but machines detect pixels.

Semantic gap is the main challenge in computer vision. The human brain – or natural neural networks – distinguishes between components on images and analyzes these components in a certain sequence. Each neuron is responsible for a particular element.

That is why building an artificial solution as superb as the human brain took decades of research and prototyping. And artificial neural networks became the greatest breakthrough in machine learning.

A fundamental task in computer vision is image classification. Thanks to the use of deep learning in image recognition and classification, computers can automatically generate and learn features – distinctive characteristics and properties. And based on several features, machines predict what is on the image and show the level of probability.

The largest growth is yet to come in such domains as automotive, sports & entertainment, robotics, and healthcare.

Medical Image Segmentation

Semantic segmentation and instance segmentation are among the core tasks of computer vision. The idea behind segmentation tasks is to teach computers to process an image at a pixel level and understand it. In simple words, computers can segment an image, paint objects in the image with different colors, and predict what is on it.

Image segmentation is especially useful in analyzing medical scans. It allows the highly precise detection of elements that can suggest more about such pathologies as tumors. As Google researchers say, by using traditional diagnosing approaches, medical experts reach agreement on the diagnosis in less than 48% of cases. However, AI-based tools assist in detecting cancer metastasis with much higher precision.

Timeliness and accuracy in diagnosing different forms of cancer are vital. It has a great impact on how early medical professionals start the correct treatment course. What AI does for saving lives cannot be overstated. And the work on computer vision medical apps is one of the top priorities of many companies worldwide.

Classification & Localization in Predictive Maintenance

One of the tendencies in manufacturing is robotic process automation (RPA). Robots assist in simplifying production workflows, successfully work hand-in-hand with human employees, and efficiently complete a variety of monotonous tasks. And computer vision is a vital part of RPA as it provides machines with human-like eyesight.

AI-led processes of monitoring equipment have become more intelligent and reliable. Now machines can predict breakdowns and help avoid costly downtimes. Likewise, computers can supervise the control of quality on production lines.

The utility industry, sensitive to whatever incidents, can harness advanced real-time monitoring capabilities. It can help better predict risk situations on time and maintain a high level of service.

Computer vision for augmented reality (AR) uncovers more possibilities specific to one or another industry. Assembly and maintenance processes get a boost thanks to the option of using real-time information integrated with real-world objects.

Manufacturing solutions require different computer vision models to solve combinations of such tasks as object detection, localization, image segmentation, and so forth.

Object Detection & Tracking in Sports

Machine learning algorithms in the field of sports have become popular for many reasons. Object detection and object tracking technologies facilitate giving feedback on the quality of actions and help reduce biases in scoring events.

Also, for tracking athletes and their performance, new ways of action quality assessment can be used across different sports. For instance, in figure skating the presentation score is a part of the total score. Thus, the accuracy of action evaluation has a high value. Likewise, assessing gymnastics performance can be dramatically enhanced.

Computer vision can also assist in the post-game analysis. And for marketing purposes, it can be employed to detect and track the visibility of brand logos in an event broadcast.

3D Computer Vision

Deep learning algorithms for computer vision deal with 2D as well as 3D format.

When action recognition became possible, it entailed extra benefits. Now it allows predicting what a player is doing at a given moment: standing, walking, running, or whatever. This capability can ease predicting tense moments in games and thus, give the audience new kinds of experience.

Massive datasets should be available to create such kind of solutions. Data to describe each action of an athlete can be gathered through sensors. This data should be translated into the format understood by computers.

After that, a video data model can be built. It stores all actions, labeled properly and assigned to the respective objects, that, in sum, shape the database. The database acts as the source of data for training a convolutional neural network model to process videos.

3D vision allows building 3D point cloud – a representation of an image in the three-dimensional format. This way, computers can catch the location and shape of an object.

3D point cloud

Building a point cloud requires measurements of different parts of objects or bodies and dynamic characteristics of these measurements. To get these types of data, engineers use special depth cameras.

3D vision is successfully employed by Amazon in retail to monitor items without scanning barcodes in the cashier-free stores. In healthcare, it enables real-time patient monitoring during surgery. 3D computer vision has also revolutionized manufacturing: it allows robots to see objects, analyze distance, and adjust related processes. This technology has become a must-have to keep head above water in a competitive business environment.
