I'm doing handwriting analysis,for that one feature is to identify the pressure.For the analysis of pen pressure, Mean gray level value is computed using the gray level values of the image pixels.But how to take these gray level values?? For reference i have attached the image.Please do help me.Thank you
if i use
meanIntensityValue = mean(grayImage(:));
is it that mean of both white and black pixels ? i want only mean of black pixels.

You can get a mask of the letters using my attached demo.
Then do
meanGrayLevel = grayImage(mask);

mask in that line of code is called binaryImage in the document_threshold.m file.
You can put the line of code to compute the mean gray level wherever you need it, perhaps right after you compute the binary image mask.
