Title:
AU DETECTION METHOD AND APPARATUS FOR IMAGE, AND ELECTRONIC DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/248841
Kind Code:
A1
Abstract:
An AU detection method and apparatus for an image, and an electronic device and a storage medium, wherein same relate to fields of image processing and predictive analysis such as artificial intelligence. The method comprises: acquiring a facial image (S201); carrying out detection processing on the acquired facial image to acquire a unified facial area (S202); by taking the facial image on which the detection processing has been carried out as an original image, inputting same into an optimized ResNet network to carry out feature value extraction, so as to output a facial feature vector (S203); and inputting the facial feature vector output by the ResNet network into an LSTM network for training to obtain an AU recognition result of the facial image (S204). According to the method, a training model can make full use of dynamic information of a facial AU change to automatically learn of a mapping relationship between AU features of a recognized object, such that the prediction precision and robustness of the training model are improved, and the performance of AU recognition of the facial image is thus improved.
