fuzzy_THv3.0.zip - SEG_FUZZY is a soft thresholding method for image segmentation. The method is based on relating each pixel in the image to the different regions via a membership function, rather than through hard decisions. The membership function of each of the regions is derived from the histogram of the image. As a consequence, each pixel will belong to different regions with a different level of membership. This feature is exploited through spatial processing to make the thresholding robust to noisy environments.

DRLSE_v0.zip - is Matlab code implements a new level set formulation, called distance regularized level set evolution (DRLSE), proposed by Chunming Li et al s in the paper "Distance Regularized Level Set Evolution and its Application to Image Segmentation", IEEE Trans. Image Processing, vol. 19 (12), 2010
The main advantages of DRLSE over conventional level set formulations include the following: 1) it completely eliminates the need for dreinitialization 2) it allows the use of large time steps to significantly speed up curve evolution, while ensuring numerical accuracy 3) Very easy to implement and computationally more efficient than conventional level set formulations.
This package only implements an edge-based active contour model as one application of DRLSE. More applications of DRLSE can be found in other published papers in the following website:
