Method and System for Selecting Motion Search Region for Image Sequences using Depth Camera Information

摘要

The present invention relates to a method for setting a motion estimation area for a color image sequence by using depth camera information and a setting system thereof and, more particularly, to a method for setting a motion estimation area for a color image sequence by using depth camera information includes an image obtaining step (S100) of obtaining a depth image including distance information to an object through a first camera, an image processing step (S200) of dividing the depth image obtained at the image obtaining step (S100) into blocks and grouping and labeling the blocks into a background area, an object inside area, and boundary area, an area determining step (S300) of extracting a motion estimation block and a motion exploration block of the object and determining a background area, an object inside area, and a boundary area of the motion estimation block and the motion exploration block, an area setting step (S400) of setting a motion estimation area when the blocks are in the object inside area or the boundary area according to a result of the area determining step (S300), and a motion vector setting step (S500) of setting a motion vector by using the motion estimation area of the motion exploration area and the motion estimation area set at the area setting step (S400).
