Hardware-Oriented Dynamically Adaptive Disparity Estimation Algorithm and its Real-Time Hardware

A reconfigurable data allocation hardware module configured to create variable window sizes to adapt the window size to the local texture on the image comprising,

• a flip-flop array configured to store and shift aligned outputs of the vertical rotator;
• wires connected to the flip-flops array arranged to sample the pixels while pixels are flowing inside the flip-flops array;
• a plurality of first sampling schemes to provide the variable window sizes;
• a plurality of second sampling schemes to provide constant number of contributing pixels in the variable window sizes to provide constant computational load for the variable window sizes;
• a plurality of multiplexers configured to select the windows to be used in disparity estimation process of multiple pixels in a block according to the selected window size.
