Abstract
The invention discloses a method and a system for generating a loop animation, which belong to the field of image generation. An artistic image is generated by constructing a program model, an inner spliced frame image is observed through an outer mask grid image, and a moire loop animation effect is generated based on a visual persistence principle. The method comprises of steps of inputting a pre-processed mask image and a pre-processed frame sequence image, or automatically extracting a key frame image from a video clip or a moving picture; determining image processing precision and the viewing distance according to a presentation effect demand, and completing the calculation and construction of a program mathematical model; a straight stripe-shaped mask raster image being automatically generated, extraction and staggered splicing of frame sequence image content being automatically completed, and a spliced frame image of an inner layer being generated. According to the method, an automatic digital process from image or animation segment input to art generation design to effect simulation and image export is realized, and the experimental property, high efficiency and art expressive force of a digital generation art method are exerted.
