Hi,
How can we find the internal width of a alphabet for a complete region and store as a array? Is there any command in MATLAB or any other way? The image file has been attached herein.
Thanks

Your question sounds like you have many images you want to measure this on. Can you show other images as well? For this image you can use find to find the first and last black pixel in your image on a specific row, but that might not work for all your cases.

Try this
im = im2double(imread('alif.png'));
im_gray = rgb2gray(im);
im_bin = imbinarize(im_gray);
[row, col] = find(~im_bin);
width_pixel = mean(splitapply(@numel, col, findgroups(row)));
It calculates the mean of pixel width across all rows in which the character is present.

That question is much more complicated, and completely automating it might need much effort. Maybe you can make it partially automatic by using ginput().
