Emerging Tech Development & Consulting: Artificial Intelligence. Advanced Analytics. Machine Learning. Big Data. Cloud

Computer vision applications have become ubiquitous nowadays. It’s hard to think of a domain where the ability of computers to “see” what’s going on around them has not yet been leveraged.

Delivering process automation and accuracy, computer vision technology is expected to have even greater momentum due to the COVID-19 pandemic as organizations have rushed to adopt automation on a larger scale.

More nuanced use cases of computer vision in different industries are also predicted to emerge with the next evolutionary leaps in artificial intelligence development; a field computer vision is a part of. Let’s look at the inroads already made by computer vision, its vast applications in different industries, and its benefits.

What is computer vision, and how has it evolved?

Computer vision (CV) is a subset of AI that enables systems to interpret information from digital images and react to it with action or recommendations. The goal of computer vision technology is to emulate human vision for performing monotonous or complex visual tasks faster and even more efficiently. 

Historically, it all started with a lot of manual coding until machine learning progressed enough to allow developers to program smaller computer vision applications and apply statistical learning algorithms for specific CV-related tasks such as pattern recognition. With AI making major strides, ML algorithms have been largely replaced by deep learning or hybrid models that rely on neural networks to transform patterns into mathematical equations for information classification. After the launch of the first commercial software back in the 1970s, computer vision applications have evolved from enabling reading devices for the blind to transforming entire industries.

Some systems powered by computer vision have achieved 99% accuracy and can even surpass human performance (for instance, in diagnostic radiology). 

The key drivers behind the surge in computer vision applications are:

  • Spreading mobile technology that allows us to create and share billions of images a day
  • Increasingly affordable computing power to process this massive amount of visual data
  • New hardware
  • A burst of deep learning algorithms

What can computer vision do? — Major computer vision techniques

With the growth in visual data and advances in computing power to process it, present-day computer vision applications rely on the following technology capabilities:

  • Object classification to assign objects in a photograph or video to predefined classes. With binary classification, the system answers a simple question whether a particular object belongs to, say, a class of apples, tourist attractions, or cats.
  • Object localization to locate an object in an image by enclosing it into a bounding box.
  • Object detection to do both of the above to many objects in an image, assigning labels and localizing objects by drawing bounding boxes around them.
  • Semantic segmentation to understand every pixel of an image and associate it with a class label (a car, a person, etc.) by creating object masks, with objects of the same class presented as a single entity.
  • Instance segmentation to do semantic segmentation and additionally identify different instances of the same class so that you don’t get just a one-color mask for three parked cars in a street view photo but label the vehicles with three different colors, identifying their boundaries.

Computer vision applications — Benefits and real-world examples

Applications for computer vision have been expanding at a rapid pace over the last decade to reach a frantic level with the onset of the COVID-19 pandemic. Organizations now invest heavily in AI-driven solutions, from retail software and healthcare platforms to advanced manufacturing and government systems. Many are even concerned that AI technology is moving too fast for them, according to a survey of business leaders conducted by KPMG. 

While there is still an overall lack of AI regulation that comes with AI explainability challenges and bias risk, computer vision technology is a safer playing field due to its maturity. Given the investment speed and immediate benefits delivered by computer vision implementation, the worldwide market of computer vision solutions is projected to grow at a CAGR of 7.6% to $19.1 billion from 2020 to 2027.
