Multiple Scanning Order in Fast Depth Estimation Algorithm

Fast algorithms for stereoscopic depth estimation typically employ processing of the input images in a Single Scanning Order (SSO). In this paper we present a novel approach that employs processing in Multiple Scanning Orders (MSO), which are then merged together into a final depth map. We demonstrate the advantages of the proposal on the example of a fast depth estimation technique [1], adaptable both for mobile platforms and FPGA. We show that application of the proposal leads to considerable quality improvement at an acceptable complexity cost.
