Abstract: A joint expression coding system based on static and dynamic expression images is disclosed, including an image preprocessing module, a dynamic expression image generation module, a dynamic weight image generation module, and a joint expression coding image generation module. A joint expression coding method based on the joint expression coding system is also disclosed. A static expression image and a dynamic expression image are combined into one image according to the coding method by adopting the joint expression coding system and method based on the static and dynamic expression images, whereby static expression information and dynamic expression information can be represented at the same time, thus improving the emotion recognition capability based on facial expressions.
