WebSo, due to a limited raster resolution, the moments computed for a contour are slightly different from the moments computed for the same rasterized contour. Since the contour moments are computed using Green formula, you may get seemingly odd results for contours with self-intersections, e.g. a zero area (m00) for butterfly-shaped contours. grammarly youtube ad actressWebOne of the most exciting features in OpenCV 4.5.1 is BEBLID (Boosted Efficient Binary Local Image Descriptor), a new descriptor able to increase the image matching accuracy while reducing the execution time!This post is going to show you an example of how this magic can be done.
