Abstract
A depth estimation system is described capable of determining depth information using two images from two cameras. A first camera captures a first image and a second camera captures a second image, both images including a plurality of light channels. In a first light channel of the plurality of light channels, the system calculates a census transform for each pixel of the first image and a census transform for each pixel of the second image. In a second light channel of the plurality of light channels, the system calculates a census transform for each pixel of the first image and a census transform for each pixel of the second image. The system generates a depth map based in part on the census transforms for each pixel of the first image and the second image in the first light channel and in the second light channel.
