In simpler terms, a Blob is a group of connected pixels which we can find in an image and all of these pixels have some common property. In computer vision, blob detection methods are aimed at detecting regions in a digital image that differ in properties, such as brightness or color, compared to surrounding regions. Informally, a blob is a region of an image in which some properties are constant or approximately constant...Apr 02, 2020 · I would suggest you read the Line Detection OpenCV blog first, and then come to this blog to better understand it.
