METHOD AND APPARATUS FOR PROCESSING LASER SPECKLE IMAGE WITH CONTRAST

摘要

PURPOSE: A method and an apparatus for processing laser speckle image are provided to improve the time resolution by providing large amount of computation with smaller computation amount and frames. CONSTITUTION: A fixed window contrast ratio calculation module(100) produces the contrast ratio image for each pixel and generates an image with the converted contrast ratio. A threshold value set module(200) establishes the contrast ratio value for each range of divided pixel number. A window size set module(300) establishes adaptive window size. An adaptive contrast ratio calculation module(400) produces the contrast ratio image in spatial aspect about a laser speckle image.
