Intel is tackling vision technology with a software release intended to foster development of applications enabling computers to recognize gestures and other sight-based effects. The company's Microprocessor Research Lab has released open-source software, which the company is calling the computer vision library, to enable developers to build vision-based applications. Announced at this week's IEEE Computer Society Conference on Computer Vision and Pattern Recognition, the computer vision library will offer functions that include gesture recognition, object tracking, face recognition, and camera calibration, said Intel spokesman Manny Vara. The library's release will help researchers engineer ways to use "computer vision" as a method for people to interact with computers.
