Abstract: High level martial arts competition is very intense, and often winning or losing depends on score of 0.01. Based on the actual demand of Wushu routine training, this paper introduces the image filtering and interactive affine transformation technology into video feedback for the requirement of high-tech auxiliary training, and forms a video feedback system based on interactive pattern creation. The user can easily define image processing operations in the video feedback to generate a variable fractal pattern in a touchable interactive manner to feedback players’ action details. Completion of each difficulty movement by martial arts athletes is feedbacked by video feedback system （DARTFISH） to help the coach in guidance and correction.
