I want to divide a binary image into 8x8(64) blocks. Then I need to count the no. of black points in each block and stored them into an 8x8 matrix. My image has the size of 120x120. Please help me to do this.

Simply define a function to count zeros:
ZeroCounterFunction = @(theBlockStructure) sum(theBlockStructure.data(:) == 0);
Then call blockproc():
blockSize = [8 8];
blockyImage8 = blockproc(grayImage, blockSize, ZeroCounterFunction);
Attached is a full demo that will create this image:
