Abstract
An in-stream disparity processing system comprises a delay block having an input for receiving an input stream of disparity cost vectors, and configured to provide a delayed stream of disparity cost vectors at an output of the delay block, by delaying the input stream by a predetermined amount; and a processing block having a cost input connected to receive the delayed stream of disparity cost vectors and a smoothing input connected to receive the input stream of disparity cost vectors, and configured to apply cost smoothing to the delayed stream based on the input stream, so as to generate, at an output of the processing block, a stream of reverse pass disparity cost vectors.
