HUMAN IMAGE TRACKING SYSTEM, AND HUMAN IMAGE DETECTION AND HUMAN IMAGE TRACKING METHODS THEREOF

摘要

A human image detection and tracking systems and methods are disclosed. A human image detection method comprises receiving a depth image data from a depth image sensor by an image processing unit, removing a background image of the depth image sensor and outputting a foreground image by the image processing unit, receiving the foreground image and operating a graph-based segment on the foreground image to obtain a plurality of graph blocks by a human image detection unit, determining whether a potential human region exists in the graph blocks, determining whether the potential human region is a potential human head region, determining whether the potential human head region is a real human head region, and regarding the position of the real human head region is the human image position by the human image detection unit if the potential human head region is the real human head region.

1. A human image detection method for detecting a human image position in a detection area, comprising:
receiving by an image processing unit a depth image data from a depth image sensor; removing by the image processing unit a background image of the depth image data for obtaining a foreground image; receiving the foreground image by a human image detection unit, which performs a graph-based segment process on the foreground image to obtain a plurality of graph blocks; determining by the human image detection unit whether a potential human region exists in the graph blocks according to an area size of each graph block; determining by the human image detection unit whether the potential human region is a potential human head region according to a similarity between the potential human region and a hemisphere model if the potential human region exists; determining by the human image detection unit whether the potential human head region is a real human head region according to an area size of a surrounding region adjacent to the potential human head region if the potential human region is the potential human head region; and determining by the human image detection unit the position of the real human head region as the human image position if the potential human head region is the real human head region.
