Problems solved by technology

In the above prior art, if the analyzed expression feature α belongs to category C1, when k is much greater than 1 or very close to 0, kα is likely to exceed the range of category C1; and when kα exceeds the range of C1, its corresponding face facial expression image effect will become more unnatural

Abstract

The invention discloses a method and a device for synthesizing a facial expression image. The method comprises the steps that the expression features of at least two reference facial expression imagesare acquired; interpolation is performed on the expression features of at least two reference facial expression images so as to obtain new expression features; and the target facial expression imageis adjusted according to the new expression features so as to form the new facial expression image. According to the technical scheme, interpolation is performed on different expression features to obtain new expression features instead of directly amplifying or reducing the existing expression features, and the new facial expression image is obtained according to the new expression features. According to the technical scheme, the synthesized facial expression image effect is natural and the facial expression image is closer to the real expression image.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for synthesizing facial expression images. Background technique [0002] Facial expression recognition is widely used in fields such as entertainment, security, human-computer interaction and social network analysis. In order to recognize facial expressions, it is necessary to train an expression recognition model, which requires a large number of expression images as training data. However, the cost of collecting expression images is high and there are many limitations. In order to solve this problem, a large number of expression images are proposed to be synthesized to train the expression recognition model. [0003] Existing emoticon image synthesis methods are mainly divided into two categories. The first type of method directly operates the facial expression image, and modifies the facial expression image by moving the pixel position of the fa...
