Patent ID: 8798168

Claim:
A terminal for video telecommunication comprising: a background scene separation unit for separating a background scene region and a human region; a background scene synthesis unit for synthesizing the separated human region and a new background scene into a synthesized picture; a picture encoder for encoding the synthesized picture for telecommunication; a picture decoder for decoding picture signals received from other party; and a telecommunication device for transmitting an encoded picture with information on a boundary between the separated human region and a background scene, and receiving the picture signals according to communication protocol; wherein the encoded picture is transmitted to a terminal of the other party through a buffer and the telecommunication device, wherein the background scene separation unit includes: a face region extraction unit for classifying cells of a picture into skin-colored cells and non-skin-colored cells based on how much skin color pixels occupy in each of the cells of the picture, for grouping connected skin-colored cells into face region candidates, and for determining a face region among the face region candidates based on whether a ratio of the number of width pixels to length pixels in the face region candidates is within a prescribed range; a general region separation unit for separating a general region outside the face region to generate a plurality of separated regions, and a region synthesis unit for determining regions corresponding to the human region from among the plurality of separated regions based on a position of the extracted face region, and for synthesizing the face region and regions determined as the human region to separate the background scene region and the human region.
