I want to ignore some part of the image rightup front.

For example, I am processing a road-car-video and I just want to process inside the lines. For starters, I assume the lines are fixed in a V shape away from me. The V shape can just be a png file.

How can I do that painlessly?

Thanks for any leads.

Create a mask corresponding to your region of interest, copy the source using the mask and process it.

Here mask means create in image with value 255 on the area you want to copy, and make rest zero.
