[0024] see figure 1 , which is a schematic flowchart of a face recognition method provided in the first embodiment of the present invention, the face recognition method includes, for example:

[0025] Step S10, using a three-frame difference method to obtain a face image from a plurality of consecutive frame images;

[0026] Step S20, making a difference between the face image and the average face image, and then using the level set segmentation method to obtain the contour line of the occluded area;

[0027] Step S30, locating the position of the contour line in the face image to obtain an unoccluded area and a corresponding unoccluded type;

[0028] Step S40, performing feature extraction on the image information of the unoccluded area to obtain local ternary pattern features and directional gradient histogram features;

[0029] Step S50, fusing the local ternary pattern feature and the directional gradient histogram feature to obtain a fusion feature; and

Abstract

The embodiment of the invention discloses a face recognition method, device and system and a readable storage medium. The face recognition method comprises the following steps: acquiring a frame imagecontaining a face image; dividing a face image region in the frame image based on Haar features, and obtaining a plurality of different regions of interest; extracting a heart rate signal of each region of interest; and performing frequency domain calculation on the plurality of heart rate signals corresponding to the plurality of regions of interest to obtain a heart rate value. The heart rate value with high accuracy can be detected and acquired in real time.

Description

technical field [0001] The present invention relates to the technical field of face recognition, in particular to a face recognition method, a face recognition device, a face recognition system and a readable storage medium. Background technique [0002] At present, face recognition technology is used in many public or private places, and it is used as a key link in the identification of entering public or private places, and it is also an important security measure in public or private places. [0003] Face recognition technology usually detects and recognizes the entire face as a whole feature. At present, this face recognition algorithm that uses the complete face as the detection and recognition object already has high accuracy and recognition speed; however, when When the face is partially occluded, the existing face recognition algorithm cannot detect and recognize the partial area of ​​the face, or the occluder on the face is also used as a part of the feature of the ...
