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.

i want to use vertical and horizontal projections to detect the pedestrains(Brighter pixels) using bounding boxes, i.e. i want to creat a candidate ROIs to get pedestrains...so i need vertical and horizontal projections....!! i want to do two-level intensity oriented projections for images...!!
