Abstract
Generally, this disclosure provides devices, systems and methods for stereoscopic depth reconstruction, for 3-D imaging, with improved probabilistic pixel correspondence searching. The method may include obtaining a first image and a second image; down-sampling the first image; down-sampling the second image; generating a reduced resolution disparity matrix for the first down-sampled image including estimated correspondence pixels from the second down-sampled image; generating a reduced resolution quality matrix including quality metric values associated with pixels in the reduced resolution disparity matrix; up-sampling the reduced resolution disparity matrix to a first full resolution disparity matrix; up-sampling the reduced resolution quality matrix to a full resolution quality matrix; and generating a second full resolution disparity matrix for the first image including estimated correspondence pixels from the second image, the estimated correspondence pixels selected from a search range in the second image.
