how to calculate texture parameters

Hello,

I have to do image processing on a lot of MRI images. The aim is to do some texture analysis on a ROI.

I = imread('0003.jpg');
figure
imshow(I) 
h = drawpolygon('FaceAlpha',0);

This program allows me to draw a ROI. How can I calculate the entropy, homogeneity, skewness, kurtosis of the ROI which I drew ?

Hi,

I understand you want to do analysis on a Region-of-Interest(ROI). We can create ROI objects, crop them and then proceed with analysing cropped ROIs individually. Refer to this answer to create ROI using freehand and cropping the ROI for further analysis.

Refer to the hyperlinks for calculating entropy, homogeneity, skewness and kurtosis

yes，sir，may be use graycomatrix、graycoprops to do texture analysis
