It turns out that something most humans neglect — the ability to see, process and then act on visual input — is astonishingly difficult to replicate in machines. That’s precisely what computer vision (CV) aims to do. While perhaps not as advanced as human sight, computer vision has advanced to the point it is very useful in business today. Here’s more about what computer vision is and how it is used in business.
What is computer vision?
Computer vision describes the process when a computer using artificial intelligence algorithms can identify and process images (photos, videos, etc.) and then create an appropriate output from the analysis because the computer can basically "understand" the content. Specifically, computer vision can classify, identify, verify, and detect objects. The developments with computer vision in recent years were facilitated by machine learning technology—in particular, the iterative learning process of neural networks—and significant leaps in computing power, data storage, and high-quality yet inexpensive input devices.
There are three main components to computer vision.
1. Acquire the image: When a digital camera captures an image, it creates a digital file composed of zeros and ones.
2. Process it: Algorithms are used to determine basic geometric elements to build images out of the binary data.
3. Analyze and understand: In this final step of computer vision, the data is analyzed. High-level algorithms are used to then make decisions based on the images.
Since the very youngest of humans can process images and understand them, the challenges of replicating that ability in machines were underestimated. What first seemed like a simple problem to solve, turned out to require decades of research. There's a lot of complexity in the visual world, and there is still plenty unknown about how human vision works and how the brain perceives visual input.
Although the field of computer vision has overcome many challenges so far, there are still hurdles to tackle dependant upon what the computer vision is being used for and the data it’s able to acquire. Computer vision requires most of data processing power and memory, plus its results can be impacted by the quality of the images/data. Computer scientists are still working on optimizing computer vision for all applications.
How is computer vision used in business?
There are infinite applications where the ability to extract meaning from “seeing” visual data is useful. Computer vision combines with other technologies such as augmented and virtual realities to enable additional capabilities.
Facial recognition, powered by computer vision, is used for surveillance and security systems and additionally the technology behind Facebook that identifies people to "tag" in photos. China uses facial recognition technology in police work, payment portals, and more. Even retail stores use the technology to monitor inventory, track customers through the store, and allow customers to bypass the cash register by paying virtually when facial recognition technology puts the items on their bill.
Plenty of car manufacturers from Ford to Tesla are scrambling to get their version of the autonomous vehicle into mass production. Computer vision is a crucial technology that makes autonomous vehicles possible. The systems on autonomous vehicles consistently process visual data from road signs to seeing vehicles and pedestrians on the road and then determine what action to take.
Computer vision in medicine helps in diagnosing disease and other ailments and extends the sight of surgeons during operations. There are now smartphone apps that allow you to diagnose skin condition using the phone's camera. In fact, 90 percent of all medial data is image-based—X-rays, scans, etc. and plenty of this data can now be analyzed using algorithms.
Digital marketing: By using computers to sort and analyze through millions of online images, marketers can bypass traditional demographic research and still target marketing to the right online audience and do this work dramatically quicker than humans could. Marketers even use computer vision to ensure ads are not placed near content that is contradictory or problematic for its audience. Financial institutions use computer vision to prevent fraud, allow mobile deposits, and display numerical information visually.
In manufacturing, computer vision makes things more effective, effective, and safe. It is used in predictive maintenance to discover an issue before any breakdowns occur as well as in quality control measures. The quantity of items a machine can verify outpaces human's ability to do the same dramatically.
The agriculture industry uses computer vision to make operations more productive by monitoring fields looking for signs of disease or pests so swift action can be taken to eliminate it. John Deere introduced a semi-autonomous combine harvester that can find the optimal route through crops after analyzing the quality of grains that are harvested. Handwriting extraction and analysis: Computer vision can translate handwritten meeting notes or creative brainstorming into digital formats which make it easier to share with others in the company. The applications of computer vision are so varied that it is hard to imagine a business that couldn't benefit from it.
