What is the underlying edge detection method of the drawassisted function?

1 Ansicht (letzte 30 Tage)
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?

Wondering the same thing - it would be really useful to know, but the documentation seems to give no hint.

Hi,
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.

Hi Priysha,
Thank you, but this do not answer the question.
An active contour or a B-spline, or... method probably are underlying this "drawassisted" function, and as Suzanne, I would like to get informations about it. Could anyone contribute?
