Computer Vision & Graphics

Digital image processing, object recognition, and the transform pipeline behind real-time 3D graphics and VR.

Image Processing Fundamentals

In 1921, a system called the Bartlane cable picture transmission service began sending newspaper photographs across the Atlantic by submarine telegraph cable, coded at the sending end into five intensity levels and…

Computer Vision and Object Recognition

Image processing answers "what should this pixel become?" Computer vision asks a harder question of the same picture: what's actually in it? Getting from a grid of numbers to "that's a car" or "that's a face" is usually…

Computer Graphics and Transforms

Turning a 3D scene into a 2D image on screen is, mechanically, a sequence of coordinate-space changes applied to every vertex in the scene — the transform pipeline 1 . Each stage answers a different question about where…
