Abstract:
1. A method comprising: scaling down a video unit c and a previous video unit c−1 to generate a reduced video unit c and a reduced previous video unit c−1; dividing the reduced video unit c into N1 portions and a buffer into N2 storing units respectively; performing a motion estimation for a target pixel of the reduced video unit c to obtain a motion vector based on pixels in a preset search window established in the reduced previous video unit c−1; assigning a first depth value to the target pixel according to the motion vector; storing the target pixel in one of the N2 storing units, wherein the rest of the N2 storing units store at least one portion of the reduced previous video unit c−1; and repeating the steps of performing, assigning and storing until all pixels of the reduced video unit c are processed to obtain a motion depth map m_map; wherein N1 is less than N2.
