reading video using vhdl

hii..

I want to read video through my vhdl code and get its frames for further processing(calculating each frame's mean, standard deviation covarience)..
i've no idea how to start..

i thought of using matlab for extracting video frames after which dealing with each frame as an image in vhdl.. but i stopped at how to read these images too
s it ok to read .jpg or .bmp file via vhdl... i don't know...

in both cases i'll be loading from my pc either video or images

any guideline for starting or any recommended tutorial this will help alot..

I would be so happy for your reply..

thanks,
Niveen..
