Title:
METHOD FOR DETERMINING VALIDNESS OF FACIAL FEATURE, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/248950
Kind Code:
A1
Abstract:
A method for determining the validness of the facial feature, and an electronic device, for use in solving the problem of high determination complexity of a machine learning-based method. The method comprises: determining attitude information and/or facial change information according to the facial feature of a first video image, the attitude information being used for representing a deflection angle of the character's head indicated by the facial feature in the first video image; the facial change information being used for representing the change in the position of the character's head in the first video image and a second video image; the second video image being the previous frame of image of the first video image in a video stream to which the first video image belongs; and then determining whether the facial feature is an invalid feature according to the attitude information and/or the facial change information, and thus determining whether to perform three-dimensional reconstruction processing on the character's face in the first video image. A pre-trained model is not required, the difficulty is low, and the processing time is short.
