happy new year!I am not sure what you need, some tips here: for binary image:you can do a convex hull, then cut the hull by the ori image, then do a region analysis.for gray image:you can use a dot(tow gaussian filter with different sigma), which can enhance the "gray convex region". tow images attached! images are processed by imagepy, It's a ui framework based on scikit-image, you can try it here: https://github.com/Image-Py/imagepy.

Does anyone know if it’s possible to calculate convexity defects (relative to convex hull) in scikit-image? An online tutorial or code sample would be much appreciated… Thanks! _______________________________________________ scikit-image mailing list scikit-image@python.org https://mail.python.org/mailman/listinfo/scikit-image
