First I'd sum the image vertically and horizontally and look for the rows and columns where the grid lines are. Then call imcrop.
[rows, columns, numberOfColorChannels) = size(grayImage);
horizontalProfile = sum(grayImage, 1);
verticalProfile = sum(grayImage, 2);
binaryHoriz = horizontalProfile < someNumber;
and so on. Give it a try.

Plot the profiles and you'll be able to tell what the number is. It might be like half the max value or something.
