I have no idea exactly what you're doing or why it would be useful. It kind of looks like you're just thresholding the image to find bright blobs and adding an offset to any columns where there are pixels above the threshold. Kind of like
binaryImage = grayImage > someValue;
columns = any(binaryImage, 1);
grayImage(:, columns) = grayImage(:, columns) + 50; % or whatever.
but I don't know why you'd want that.
