abstract = "The paper presents a new fractal color image compression method,
called Fractal Hierarchical Color Block Coding (FHCBC), which
transforms the three-color planes of a color image into a
one-component image by extracting correlation among them. It
hierarchically divides the three-color planes into homogeneous
blocks, and for each such block, the variance of pixels'
trichromatic coefficients is within a certain threshold value.
Then, each block is represented by its mean value of the pixels'
trichromatic coefficient ratios, and just a one-component image is
composed and compressed by fractal coding. In the decoding
process, the reconstruction is carried out by a fractal decoding
algorithm and the associated mean values of trichromatic
coefficient ratios. In comparison with the well known
three-component Separated Fractal Coding (SFC), the suggested
method generates performance gains in running time, high
compression ratio and equal level of reconstruction quality.",
