Please help me on how to Compute Height of the each Gradient text block.. Consider width,W to be the same as the height,H. With these H and W, how to get one square block? and how to Move this square as a sliding window? after this for each sliding window, how to plot a histogram to choose highest peak. lastly Display all pixel in the highest peak as white pixels in the separate image. I need to implement it using MATLAB. Any help is greatly appreciated! Thamk you!

You could use blockproc() if you want it to move along in "jumps" (non-overlapping blocks), or you could use nlfilter(). But if your image is, say, a million pixels, do you really want to compute and display a million histograms?

Of course - use the max() function.

After finding the max of the peaks, how do we display a white pixel there?
