Abstract
In one embodiment, a method for tracking includes capturing a first frame of the environment using a first camera, identifying, in the first frame, a first patch that corresponds to the first feature, accessing a first local memory of the first camera that stores reference patches identified in one or more previous frames captured by the first camera, and determining that none of the reference patches stored in the first local memory corresponds to the first feature. The method further includes receiving, from a second camera through a data link connecting the second camera with the first camera, a reference patch corresponding to the first feature. The reference patch is identified in a previous frame captured by the second camera and of the second camera. The method may then determine correspondence data between the first patch and the reference patch, and tracks the first feature in the environment based on the determined correspondence data.
