04 Apr 2014 Adaptive kmeans Clustering for Color and Gray Image. Automatically cluster a Color or Gray image. No need for specify number of cluster. Author: ankit dixit

Ankit the line and column number are mentioned in error message itself. Can you answer my question regarding version in which you developed it? Also do you assume the two images to have same number of pixels/image size or not?

03 Apr 2014 Image fusion: resolution merge (improve spatial resolution) GUI for improving spatial resolution of image by RGB-HSI image fusion Author: Kateryna Artyushkova

Dear Kateryna Artyushkova, your code is good. I wish to clarify one hing. We fuse images where we have high spatial image of high resolution and low spatial resolution having 3 or more spectral bands for the same area, i.e. more pixels and less pixel size in highres case than lowres image. So we need to match iamge sizes first in order to run the command HSV_sub(:,:,3)=highres; else it will give error for "Subscripted assignment dimension mismatch".
Where in your code you take care of this, please let me know.
Thanking you, Vandita

03 Apr 2014 A Fast Image Segmentation using Delaunay Triangulation A fully automated process that does not require initial estimate of number of clusters. Author: Abbas Cheddad

Hi Abbas,
I am more comfortable to use simple code then GUI based. Can you please send me that version instead of the GUI one.
Hope you will respond soon as you have done in past.
Thanks in advance for your help:)

03 Apr 2014 Adaptive kmeans Clustering for Color and Gray Image. Automatically cluster a Color or Gray image. No need for specify number of cluster. Author: ankit dixit

I am using Matlab 7.8. Will your code work or I have to recode somethings?
I get an error when I run it on a gray image:
=============
??? Error: File: adaptcluster_kmeans.m Line:
72 Column: 3
Expression or statement is
incorrect--possibly unbalanced (, {, or [.

Please suggest modifications.

04 Sep 2012 variogramfit fits different theoretical variograms to an experimental variogram Author: Wolfgang Schwanghart

I wish to fit a hole effect model to my data using this function. Is there anything existing or if I have to mmodify, what should I take care in addition to adding an equation for that in this code?
