09 Jan 2014 Hill-Climbing Color Image Segmentation color image segmentation using hill-climbing algorithm and kmeans in CIE Lab. Author: YIQUN

Can you include a screenshot of a demo image?

26 Nov 2013 Schlee.m Plotting routine for Gravel, Sand, Mud Author: Matthew Arsenault

Could you possibly include a screenshot?

26 Nov 2013 SFTA Texture Extractor Implementation of the SFTA algorithm for texture feature extraction. Author: Alceu Costa

Why not include those blog images here as a screenshot, so people can see what it does?

26 Nov 2013 Shepard_Ternary_Plot Shepard ternary plot for sand, silt, clay distributions Author: William Waite

Hard to tell what it does without a screenshot.

13 Oct 2013 Image overlay Overlay a binary mask onto an image using a specified color Author: Steve Eddins

bwperim is not the only way to create outlines. It would be nice if imoverlay were smart enough to see if the input was a binary image, or a cell array that is the output of bwboundaries. A lot of times we threshold and then call bwboundaries. It would be a nice enhancement if it could take the output of bwboundaries as the location of the outlines to draw.

21 Jun 2014 SimpleColorDetection Script to do simple color detection in RGB color space. Finds red objects in the image. Author: Image Analyst IPlover

Why does it show that you don't have IPT even though i have IPT. I've checked using ver too that i have IPT.

Anyways, after continuing it shows out of memory later. I've tried using matlabpool but it didn't have much effect.
