Are there any open source implementation of the snakes or watershed segmentation algorithms?

I'm working in a graduation project whose goal is to perform a comparative analysis of segmentation algorithms. I have implemented in C++ a few segmentation algorithms in a undergraduate research project that I have participated (Otsu's method and the EM/MPM algorithm for example). I am planning to compare the algorithms that I have i...

thresholding grayscale image minimum error method algorithm

Hello, I am writing software that thresholds 24-bit color JPEGs. Currently the system uses a threshold value that I have calculated manually through trial and error using 1 sample of each document type. This method works but is prone to error if there is significant dirt/smudges on the document. The software uses IPP for decoding th...
