I am traying to make a programm for leaf disease detection to group of diseases and i want to extruct the features by GLCM , how could i classify the pictures using statistica (standard diviation and confidence interval)

thanks for all

See my glcm demo, attached.

Also search for "leaf" - it's one of the most popular items for some reason.

MATLAB: Hello, Can someone suggest me how I can do 2SD threshold for CARDIAC MRI.

Try this:

theMean = mean2(grayImage);
sd = std2(grayImage);
threshold = theMean + 2 * sd;
binaryImage = grayImage < threshold;

Now it's not clear what "Pixels darker than the threshold are then removed from further analysis." means, but for example if you wanted to blacken those pixels and leave pixels above the threshold as the original gray level, you could do

grayImage(binaryImage) = 0;

If you simply wanted a list of gray levels above the threshold then you could do this:

pixelsToUse = grayImage(~binaryImage);

Note however that that is a vector, not a 2-D image. Please explain exactly what "removed from further analysis" means.
