Human face-based living body detection method and device, electronic equipment and medium

The invention discloses a human face-based living body detection method, relates to the technical field of human face recognition, and is used for solving the problem of low living body detection efficiency caused by long time consumption of matching actions. The method specifically comprises the following steps: acquiring an infrared human face image and a color human face image at the same moment; adjusting the infrared human face image/color human face image to a preset size to correspondingly obtain a first infrared image/first color image; converting the first infrared image into a Gray matrix, converting the first color image into an RGB matrix, and fusing the Gray matrix and the RGB matrix to obtain a fusion matrix; and inputting the fusion matrix into an image processing model to obtain a detection result of determination of whether a living body exists or not. The invention further discloses a human face-based living body detection device, electronic equipment and a computer readable medium. 本发明公开了一种
