Patent Classification: ["382", "118000"]

Abstract:
The disclosure discloses an action unit (AU) feature recognition method, which includes: acquiring a real-time image shot by a photographic device and extracting a real-time facial image from the real-time image by use of a face recognition algorithm; inputting the real-time facial image into a pretrained facial mean shape and recognizing t facial feature points from the real-time facial image by use of the facial mean shape; determining feature regions matched with each AU in the real-time facial image according to positions of the t facial feature points, extracting local features from the feature regions and generating multiple feature vectors; and inputting the multiple feature vectors into pretrained AU classifiers matched with the feature regions respectively to obtain a prediction result of recognition of the corresponding AU features from the feature regions. The disclosure also discloses an electronic device and a computer-readable storage medium.

Claim (Index 5):
The electronic device of  claim 1 , wherein training steps for the predetermined AU classifier comprises:\n a sample preparation step: collecting a facial sample image, cropping an image region matched with each AU from the facial sample image as a positive sample image of the AU and preparing a negative sample image for each AU; a local feature extraction step: extracting local features of the positive sample image and negative sample image of each AU and generating corresponding feature vectors; and a model training step: performing learning training on a Support Vector Machine (SVM) by use of the local feature of the positive/negative sample image of each AU to obtain the corresponding AU classifier.
