Scene adaptive filter design for improved stereo matching

摘要

A method is provided that includes generating coefficients of a scene adaptive filter (SAF) based on differences between values of neighboring pixels in a representative two dimensional (2D) image, and applying the SAF to a plurality of corresponding 2D images.

1. A method comprising:
generating coefficients of a scene adaptive filter (SAF) based on differences between values of neighboring pixels in a representative two dimensional (2D) image; and applying the SAF to a plurality of corresponding 2D images, wherein generating coefficients comprises applying each test filter of a plurality of test filters to the 2D image, computing a statistical measure of efficacy for each test filter based on absolute differences computed for each pixel of interest of a plurality of pixels of interest in the 2D image as filtered by the test filter, wherein the absolute differences for a pixel of interest are absolute differences between the pixel of interest and each pixel in a horizontal shift range centered on the pixel of interest; and selecting coefficients of a test filter of the plurality of test filters having a best statistical measure as the SAF coefficients.
