Obtaining blocks is a matter of simple indexing

 block=yourImage(m1:m2, n1:n2);

where m1,m2,n1,n2 are appropriate indices of the corners of a particular block. Once you have a block, its histogram can be obtained using imhist(block).

[pixelCounts, grayLevels] = imhist(grayImage);
[maxCount, indexOfMax] = max(pixelCounts);
grayLevelAtMax = grayLevels(indexOfMax);
