| Abstract: | A new image compression coding approach based on Walsh quad-subband dividing is developed by combing the merits of double three-cubed interpolation and improved fractal encode. Experimental results show thatcompared to basic automatic fractal coding method,the new approach needs less computation time and higher compression ratios are obtained with no apparent depression on the quality of the reconstructed image. |
