Gray Level Run Length Image Statistics
This matlab program computes several image statistics from a gray scale image using the gray level run length matrix, these are:
1. SHORT RUN EMPHASIS (SRE)
2. LONG RUN EMPHASIS(LRE)
3. GRAY LEVEL NON-UNIFORMITY (GLN)
4. RUN PERCENTAGE (RP)
5. RUN LENGTH NON-UNIFORMITY (RLN)
6. LOW GRAY LEVEL RUN EMPHASIS (LGRE)
7. HIGH GRAY LEVEL RUN EMPHASIS (HGRE)
The function also accepts a mask to enable the user to analyze only certain regions of the image. See the script for a complete describtion.
Example:
I = imread('cameraman.tif'); % read an image
imshow(I) % show the image
mask = ones(size(I(:,:,1))); % we want to analyze the whole image
quantize = 16; % quantize the image into 16 levels
[SRE,LRE,GLN,RP,RLN,LGRE,HGRE] = glrlm(I,quantize,mask) % compute the statistics
