Image Processing Method and Device

An image processing method, comprising:

• receiving encoded data of a video image frame and depth data corresponding to a contour of a foreground image in the video image frame, wherein in the video image frame, according to the contour of the foreground image, first encoding is performed on pixels of a video image inside the contour of the foreground image, and second encoding is performed on pixels of a video image outside the contour, to obtain the encoded data corresponding to the video image frame, and wherein an encoding rate of the first encoding is higher than an encoding rate of the second encoding;
• segmenting, according to the depth data, the video image frame to obtain the foreground image in the video image frame;
• and
• playing the foreground image.

An image processing device, comprising:

• a collecting module configured to collect a video image and a depth map of an object;
• a contour segmenting module configured to segment, using the depth map, a video image frame corresponding to the video image at a same moment to obtain a contour of a foreground image in the video image frame;
• a video encoding module configured to perform, according to the contour of the foreground image, first encoding on pixels of a video image inside the contour of the foreground image in the video image frame and second encoding on pixels of a video image outside the contour in the video image frame, to obtain encoded data corresponding to the video image frame, wherein an encoding rate of the first encoding is higher than an encoding rate of the second encoding;
• a first output module configured to output the encoded data corresponding to the video image frame;
• and
• a second output module configured to output depth data corresponding to the contour of the foreground image.

An image processing device, comprising:

• a receiving module configured to receive encoded data of a video image frame and depth data corresponding to a contour of a foreground image in the video image frame, wherein in the video image frame, according to the contour of the foreground image, first encoding is performed on pixels of a video image inside the contour of the foreground image, and second encoding is performed on pixels of a video image outside the contour, to obtain the encoded data corresponding to the video image frame, and wherein an encoding rate of the first encoding is higher than an encoding rate of the second encoding;
• a foreground image segmentation module configured to segment, according to the depth data, the video image frame to obtain the foreground image in the video image frame;
• and
• a foreground play module configured to play the foreground image.
