27 Dec 2011 Local Adaptive Thresholding Threshold with local statistics, such as mean or median. Author: Guanglei Xiong Tann, Hokchhay

Great code, but not applicable to my type of images. I'm trying to make the threshold automated since I have a hundred thousands of this kind. I appreciate any suggestions.

18 Nov 2011 Gradient using first order derivative of Gaussian Output the gradient image of a grayscale image Author: Guanglei Xiong prab, Yad

Hey, nice job man! I can easily visulaize the variations in my image.
But what if i m in 3D. With image in 2D and a time factor that is adds to the third dimenstion ?
18 Oct 2011 Fuzzy c-means thresholding Thresholding by 3-class fuzzy c-means clustering. Author: Guanglei Xiong Diggs

Hi Guanglei,the code is so nice on biological images.and fair on remote sensing images.have tried to test both methods on remote sensing images but results show otsu is better.
though i have used tested your code on several remote sensing images,I have failed to understand how the code operates.all is that your code segments the image into three classes using FCM clustering thresholding based on 3-class Fuzzy clustering,where by the threshold is obtained by averaging the maximum
in the class with the smallest center and the minimum in the class with the middle center. am i right or wrong about your method?.hope to hear from you.chao
27 Sep 2011 Local Adaptive Thresholding Threshold with local statistics, such as mean or median. Author: Guanglei Xiong Shashi

I did apply this algorithm on my images but it didn't work out completely. There is a research paper by Q.Huang et.al. which speaks about Otsu's thresholding using adaptive window. I would like to know if somebody has implemented that.

Had anyone here used this code for processing trabecular micro CT images? Appreciate your feedback on the outcome. Thanks.
