How to remove header line (Shirorekha) from devanagari word/text?

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');

the steps are very simple...hope you are able to follow

STEP 1 : copy the binary image matrix J as another matrix ..lets say 'K'....by K = J . So now....K has all the values same as J.

STEP 2 : apply a 'for' loop for the matrix K, and check all the rows of the matrix K.

STEP 3 : Turn all the pixel values of the shirorekha row to white(or background value).

Done :)

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).
