Method and system for generating loop animation

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.

Description

technical field [0001] The invention relates to a method and system for generating circular animation, belonging to the field of image generation. Background technique [0002] The moiré effect is a phenomenon in physics. It is often seen as an irregular stripe-like interference pattern that may be generated when the spatial frequency of the pixels of the photosensitive element is close to the spatial frequency of the stripes in the image. Further combining the visual effects of moiré with the art of frame animation produces an interactive still image with a dynamic looping effect. That is to say, a group of frame sequence patterns are stitched together into an image in the form of stripes one by one. When a group of evenly spaced black grid images are overlaid on the image and slide continuously, one of the frames will be displayed at a certain moment and the remaining frames will be blocked, and displayed in sequence Frame-by-frame content, and then based on the principle...

Problems solved by technology

[0003] The above technology has the conditions to be further expanded and applied to more scenarios, such as large-scale art landscape installations, building facades or interior decoration interfaces, etc., and its interest, symbolism, and appreciation can greatly increase the attractiveness and memory of the application object. Points and symbolic meanings, attracting more viewers to appreciate the charm of visual art while feeling the connotation of cultural atmosphere, highlighting creativity and publicity value; The method of manually drawing effect images is inefficient and difficult to meet the needs of use, and the simple striped grille will appear monotonous and rigid, lacking in artistry and expressiveness; traditional multimedia screens, water curtains or light shows have poor interaction with personnel, There is no sense of participation, and it is not easy to attract the attention of mobile people. The present invention discloses a method for generating a loop animation. When the viewer walks back and forth in front of the image or landscape device, it can be observed that the content of the image seems to follow the footsteps Moving and constantly changing activities, based on the principle of "visual residue", a circular animation effect is generated, and the audience is impressed and experienced through interactive participation
