Embodiment Construction

[0048] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The specific embodiments described here are only used to explain the present invention, and are not used to limit the protection scope of the present invention.

[0049] The principle of the present invention is: under normal illumination, or under the condition of auxiliary lighting at night or infrared supplementary light of the camera, the video signal of the analog or digital camera is collected, and the collected video image is processed to find the video signal in the current image. The position of the face is analyzed. If there are obvious occluders on the face features, such as sunglasses or masks, the system will give an alarm signal. Most of the current mainstream video surveillance systems only have simple image acquisition and compression storage functions. This product can add the intelligent alarm function of face occlusio...

Abstract

The invention discloses a face occluder identification method. The method comprises the following steps of: acquiring a plurality of images from a video camera system, and determining the region wherein the face is positioned in each image of the plurality of images; counting coordinate values of the central position of each organ and the number of the coordinate values in the plurality of images having the face image region; determining the coordinate value, in accordance with the central position of each organ in a normal face image, of the coordinate values as the position of an organ; and determining the occlusion situation of the position of the organ according to the number of the coordinate values of a certain organ, and determining the abnormal characteristics of the position of each organ in the face image. According to another aspect, the invention also discloses a face occluder identification device. The face occluder identification device is used for acquiring image data from the video camera system to determine the abnormal characteristics of the position of each organ in the face image. By the method and the device, abnormal situations such as an occluder and the like at the positions of main organs of the face can be identified efficiently, and the method and the device are particularly applicable for video systems, needing vigilance and surveillance, of banks, jewelry shop and the like.

Description

technical field [0001] The present invention relates to a facial feature recognition method and a corresponding device, in particular to a face occlusion recognition method and a device thereof. Background technique [0002] Most of the current video surveillance systems are composed of front-end cameras and back-end image acquisition and compression storage functions, which are called "digital image recorders" or "DVR", and mainly include the following features: [0003] This kind of video surveillance system can collect the analog signal of the camera in real time, convert it into a digital signal, and compress the digital signal by the processor, and store it in the local hard disk or CD. [0004] This kind of video surveillance system can usually transmit the video information of the scene to the main control room in real time through the network, and the staff can monitor the situation on the spot in real time. [0005] This type of video surveillance system usually pr...
