Texture animation by means of the generalized Fourier filtering process [Animation de texture grâce à un filtrage de Fourier généralisé].




Sixteen frames from the generalized filtering process. The "seed" picture (STAR, see figure "Four tool pictures") providing, after an appropriate rotation, the kernel picture (not displayed on this figure); denoting R the rotation operator, each frame of this picture can be defined as: 
                    GF(SCM1(GF(STAR,R(STAR,angle))),GAUSS)
where angle varies within [0,pi/2] with a step of pi/32.
