Faster compress image coding based on interpolatory orthonormal multiwavelets

Long coding time is the main problem in image compression based on Fractal at present, mainly due to its heavy computation of searching the best-match domain block for each range block. A fast compress image coding algorithm is proposed. At coding, the interpolation based on orthogonal multi-wavelets is used to compress the original image, and then use the basic fractal coding algorithm to compress; during decoding, the use of the basic fractal decoding algorithm to decode, and then use interpolation orthogonal multi-wavelet transform to restore the image. Experimental results show that compared to directly fractal code, this method reduces coding time, and signal to noise ratio, compression ratio, etc. have improved.
