WebOct 27, 2024 · Why thinning is use in image processing? Thinning is a morphological operation that is use to remove selected foreground pixels from binary images, somewhat like erosion or opening. In this mode it is commonly use to tidy up the output of edge detectors by reducing all lines to single pixel thickness.
