A Study on Animating Picture with Flicker
Details
In this paper, we propose a new simple method of making animations that have motion like water surface and sunlight through foliage by adding flicker to a picture. In our method, we generate height data of surface from an original image, and, by oscillating them, make a sequence data. The luminance values are fluctuated based on these data by using bump mapping, and thus, the animations are generated. Various motion can be obtained by operating some variable numbers. For example, when we determine the amplitude by considering the initial height of near pixels, it is able to control a smoothness of motion. Additionally, when different frequencies are applied to each area of image, they move at different speed. It was revealed that it is effective in expressions like the perspective.
