Abstract

The invention discloses a neutral expression forward face picture method and device, wherein, the method comprises the following steps: the face picture in a data set is processed through the face three-dimensional reconstruction to obtain the face geometry and the reflection attribute of the face; The training input is a face image, and the output is a neutral face geometry and its complete reflection attribute depth neural network. A network of final positive neutral face images is generated by pre-training, and the neutral face geometry and complete reflection attributes extracted from theneutral forward face images in the training set are used as inputs, and the images are output as targets during pre-training. The depth neural network and the network generating the final positive neutral face image are cooperated and trained simultaneously in order to reduce the generation countermeasure error. This method can generate neutral forward face images with realistic sense, only need to input a single face image, and is not limited by the expression, face angle and orientation of the face image.

Description

technical field [0001] The present invention relates to the technical field of picture processing, in particular to a method and device for a positive face picture with a neutral expression. Background technique [0002] The concept of deep learning originated from the research of artificial neural networks, and the multi-layer perceptron with multiple hidden layers is a deep learning structure. Deep learning combines low-level features to form more abstract high-level representation attribute categories or features to discover distributed feature representations of data. [0003] The positive face picture with a neutral expression is a face portrait photo that is required for formal documents and occasions. In some application scenarios, when people only have a non-positive face picture with an expression, they need to obtain a positive face picture with a realistic neutral expression. In related technologies, the expression of the input face is limited, and the angle and...
