摘要：This paper presents a novel circular effect generation approach. In general, pixel location in an image can be represented with i and j coordinate. To manipulate (i,j) coordinate system easier, we transform (i,j) coordinate system into (ρ,θ) coordinate system. Two parameters are used for generating circular effect: R and T. After applying selected R and T in (ρ,θ) coordinate system, (ρ 2 ,θ 2 ) are obtained. Finally, (ρ 2 ,θ 2 ) signals are inverse-transformed into (i,j) coordinate system and (i 2 ,j 2 ) is obtained. Experimental results introduce performance comparison.
