WebFirst, you need to set filterByColor = 1. Set blobColor = 0 to select darker blobs, and blobColor = 255 for lighter blobs. By Size : You can filter the blobs based on size by setting the parameters filterByArea = 1, and appropriate values for minArea and maxArea. E.g. setting minArea = 100 will filter out all the blobs that have less then 100 ... WebAs already pointed out, it does not make sense to compute MSER on a binary image. MSER basically thresholds an image (grayscale) multiple times using increasing (decreasing) thresholds and what you get is a so called component tree like this here. on the hush reviews https://myfoodvalley.com
