After thresholding with the functions, or yourself like this:
binaryImage = grayImage > someThreshold;
call imresize() to make the image 8 by 8
binaryImage = imresize(binaryImage, [8,8], 'nearest');
i didn't get your ans..please give some examples or write complete code for this

Search the File Exchange (link) for Image Analyst’s demonstrations.
Experiment with your image to get the result you want. See the documentation for the functions we referenced.
