Abstract

In video coding at high compression rate, fractal compression schemes in spatial domain have outstanding blocking artifacts and compression schemes in wavelet transform domain have ringing artifacts at edges. In order to compensate these disadvantages, we propose a fractal video coding in wavelet transform domain which leads to clear edges without blocking artifacts even at high compression rate. The proposed method performs variable block sized motion estimation by using correlation among different subbands. Then the wavelet coefficients which are not encoded effectively by the motion estimation are compressed by inter-frame fractal coding which predicts fine scale subbands hierarchically from the next coarser scale subbands. Computer simulations with several test images sequences show that the proposed method shows better performance than the conventional video coding methods using fractal and wavelet.
