Embodiment Construction

[0098] The method for human body re-identification based on part segmentation provided by the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0099] Such as figure 1 As shown, the human body re-identification method based on part segmentation provided by the present invention includes the following steps in order:

[0100] 1) Image data acquisition: First, use the Kinect camera to collect multiple frames of images of the scene to be detected, and then extract the foreground image of the human body from the above image, and after denoising, segment it into part images according to the parts and filter and save them; all the images that need to be queried Save the human body part image as a query set, save all collected human body part images as a candidate set, and save the collected human body part images according to the image serial number and part;

[0101]Specific steps are as follows:

[0102] 1...

Abstract

A human body reidentification method based on portion segmentation is disclosed. The method comprises steps of image data acquisition, rough identification, fine identification and the like. The method has effects that modern clothes have many styles and colors, a color of sleeves is different from a color of a body portion, and colors of trousers of a thigh portion and a crus portion are different; in a monitoring camera, head information is usually subtle so that a characteristic with a large distinction degree is not easy to find, and feet are small and are not easy to collect; and based on the above condition, a human body, except for the head, is divided into 9 portions of a body, a left / right upper arm, a left / right lower arm, a left / right thigh and a left / right crus, and reidentification is performed and a high identification rate is possessed. Through rough identification, a candidate set human body whose color is close to that of a query set can be extracted, but a search scope can not be reduced. Based on the rough identification, for a body portion image, a method of projection is used to extract a pattern of the body portion and position information of the pattern so that the identification rate is further increased.

Description

technical field [0001] The invention belongs to the technical field of computer vision and image processing, and in particular relates to a human body re-identification method based on part segmentation. Background technique [0002] With the rapid development of computer vision technology, due to the non-contact characteristics of human body re-identification, it has broad application prospects in public safety, medical care, criminal investigation, etc. As the basis for high-level applications such as pedestrian posture, action, and behavior recognition, human body re-identification has important research significance. [0003] The current human re-identification research mainly has two directions: (1) Method based on feature representation. Although this type of method can improve the accuracy of re-identification to a certain extent, it only considers the human target from the overall characteristics, and lacks the spatial constraint information on the human target.
