I was able to plot the horizontal projection of the image and came to know that where is shirorekha... but how to remove that headerline?
my code is...
I = imread('marathi_word_3.jpg'); imshow(I); title('Original Scanned Document');
level = graythresh(I); doc_binary = im2bw(I,level); % figure, imshow(doc_binary); title('Binary Document');
J = imcomplement(doc_binary); figure, imshow(J);
% horizontal projection horizontalProjection = mean(J,2); figure, plot(horizontalProjection, 'b-'); title('Horizontal Projection/Horizontal Histogram');

I think the problem was/is knowing which rows are the "shirorekha row". You have not given the algorithm for that. I think you might be able to do it by
shirorekhaRows = horizontalProjection < someValue;
This relies on the fact that the row with the line that goes most of the way across the image will be the darkest rows in the vertical profile (horizontalProjection).
