MISSING FEET RECOVERY OF A HUMAN OBJECT FROM AN IMAGE SEQUENCE BASED ON GROUND PLANE DETECTION

摘要

An object segmentation system that includes a first type of sensor, a second type of sensor and a control circuitry. The first-type of sensor captures a sequence of color image frames of a scene. The second-type of sensor captures a depth image for each corresponding color image frame of the sequence of color image frames. The control circuitry generates a point cloud for an input color image frame. The control circuitry segments a foreground human object from a background of the input color image frame. The control circuitry detects a ground plane for the scene captured in the input color image frame. The control circuitry recovers a feet region in a defined region from a level of the detected ground plane. The control circuitry extracts the foreground human object with the recovered feet region from the background of the input color image frame, based on the detection of ground plane.
