1. A method for video processing, said method comprising: in a computing device: determining a depth value for each pixel of a subset of pixels in an image frame based on calculated motion vectors of said each pixel of said subset of pixels, an average vertical pixel velocity of said image frame and an average horizontal pixel velocity of said image frame, wherein said average vertical pixel velocity and said average horizontal pixel velocity are determined based on pixels with predetermined motion vectors in said image frame, wherein said determination of said depth value of a pixel of said subset of pixels in said image frame is based on a first difference and a second difference, wherein said first difference is a difference between a vertical velocity of said pixel in said image frame and said average vertical pixel velocity of said image frame, and said second difference is a difference between a horizontal velocity of said pixel in said image frame and said average horizontal pixel velocity of said image frame; and generating a stereoscopic image pair for said image frame based on said determined depth value for each pixel in said image frame.
