Embodiment Construction

[0036] Various details involved in the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that the described embodiments are only intended to facilitate the understanding of the present invention, rather than limiting it in any way.

[0037] Gender recognition based on gait plays an important role in improving the monitoring system's ability to understand the monitoring scene and improving the recognition ability of the gait recognition system. Utilize the gait average contour method, the present invention has realized a long-distance gender recognition system based on gait; as figure 1 A flowchart showing a gait-based gender recognition method, including two parts: training and recognition:

[0038] The training process includes the steps of: performing human body contour segmentation and normalization on gender-marked gait video sequences; gait cycle calculation and video sequ...

Abstract

The invention discloses a method for identifying sex based on walking, comprising two processes of training and identification. The walking video sequence marked with sex has characteristics picked up, and the characteristics picked up are trained for modeling so as to obtain sex classification model parameters; video data or camera data containing a walker have characteristics picked up, and the characteristics picked up are inputted in the model obtained by training so as to obtain the sex of the walker in the video. The sex identification based on walking is very important to improve the capability of the next generation intelligent monitoring control system in understanding monitoring scenes. When the invention is used for the intelligent vision monitoring control system, the invention can help the monitoring control system identify sexes of people in monitoring scenes, make the monitoring control system really understand what's going on in monitoring scenes and apply different safety levels according to different sexes of people in monitoring scenes; when the invention is used for the rough classification of people based on the walking identification, sexes of people can be judged, and the identification of a walker can be searched based on sex; the invention can also be used to analyze whether a customer is fond of specific products or specific entertainments.

Description

technical field [0001] The invention belongs to the field of pattern recognition, relates to technologies such as image processing and computer vision, and particularly relates to gender recognition based on gait. Background technique [0002] With the development of technology and the gradual reduction of the price of hardware equipment, a large number of surveillance cameras have been installed in various places, especially those places that are sensitive to security requirements, such as airports, communities, banks, parking lots, military bases, etc. Visual monitoring of dynamic scenes is a frontier research direction that has attracted much attention in recent years. It detects, recognizes, tracks targets and understands their behavior from image sequences captured by cameras. Although surveillance cameras, which are the extension of human vision, are widely used in commercial applications, the current surveillance systems can only record video for later evidence collec...
