The problem, more precisely stated, is this:

Detect a dark border around the images, and then remove the dark region,
retaining the rest of the image. The resolution of the image remains the
same, but the size decreases because of this removal of border.

Dear Siddarth,
I suggest that you post your message again, but you need to be
more specific about what needs to be done.

 From what you wrote, I can see several *very different* interpretations:
1) Detect a dark border around each image and then crop the border
off, making the final image smaller, having fewer lines and fewer pixels
per line.

2) Detect the dark areas of an image and then brighten them up,
but leave the image with the same dimensions.

3) Something else?

regards,
Jim
