Hello I read and saved images in a mat file. I need to know how to extract glcm features from the images saved in the mat file,
Here is the code I used. Thanks
img1 = imread('.....');
img2 = imread('.....');
fetch = {img1, img2};
save fetch

You are not storing the images that you read, and you overwrite the variable fetch with constants. You are not going to be able to extract features from that cell array.
img1 = imread('.....');
img2 = imread('.....');
fetch = {img1, img2};
save fetch

Everything else is just a matter of loading the data (if needed) and using cell indexing to extract an individual image.
Note: JPEG images are almost always RGB, even when they look gray.

MATLAB command GRAYCOMATRIX helps to find the GLCM. Please refer to the documentation at:
