This is a simple implementation of the SGM algorithm with the Birchfield/Tomasi pixelwise matching cost using the OpenCV library. It was created for a school project. It currently runs on one thread only and is relatively slow. Also, there is no postprocessing of the disparity map so there are visible errors in the disparity map.

WebMutual information cost function is not implemented. Instead, a simpler Birchfield-Tomasi sub-pixel metric from [BT96] is used. Though, the color images are supported as well. Some pre- and post- processing steps from K. Konolige algorithm cv.StereoBM are included, for example: pre-filtering ( XSobel type) and post-filtering (uniqueness check ... WebThe result values are passed to the Birchfield-Tomasi pixel cost function.-uniqueness_ratio (default = 10): Margin in percentage by which the best (minimum) computed cost function value should “win” the second best value to consider the found match correct. Normally, a value within the 5 - 15 range is good enough. iris lab solutions hand sanitizer
