Fill the region of rotating bounding box with nearest pixel value

I have a rotating bounding box in an image. I want to fill region inside the bounding box with nearest pixel values outside the bounding box. I am thinking of going through the regions of the bounding box iteratively and calculating the left and right neighbour value for each row and fill that row with those values. Before doing that i want to know is there an elegant and better way of doing that in Matlab or opencv (python) by using some functions

Hi Prashant

You can design the appropriate mask and then use the functions:- conv2 / filter2 / imfilter to apply the mask to your image and get the desired results.

Hope this helps.
