What is the underlying edge detection method of the drawassisted function?
조회 수: 2(최근 30일)
In the Image Segmenter App, there is a function called 'Assisted Freehand ROI Drawer', which is based on the function 'drawassisted'. I have been searching everywhere, but I couldn't find on which edge detection algorithm (i.e. Canny, Sobel, Prewitt) this is based. Does anyone have a place where they found this?

Perhaps the following Blog Post can help you determine algorithms used in Image Processing Toolbox:
It does not mention the edge detection algorithm used in implementing the "drawassisted" function, but talks about the Image Processing Toolbox as a whole. Hope it gives you the required idea.
