image pixel data are stored as a matrix format named "A1" (688 x 512) - grey-scale Since the data should be converted to a double precision format,
Data_d = double(A1.Data);
1. How do I compute RMS, skewness and kurtosis images?
2. Also how do i compute PDFS plots for those images?
here is a code I wrote..
I=imread('A1');
I2 = im2double(I);
s=skewness(I2(:))
figure;imagesc(s);colormap jet;colorbar;
k = kurtosis(I2(:)
figure;imagesc(k);colormap jet;colorbar;
figure that pop up after running a code is definitely wrong.. but I dont know why..
figure I got
figure I need to get
