The proposed approach (CICMFCSA), firstly, compose the one-plane image using the pixel’s
trichromatic coefficients. One-plane image in traditional square structure is represented in Spiral
Architecture for compression. On this Spiral Architecture image, proposed modified Fractal grey
level image coding algorithm (MFCSA) is applied to get encoded image. In this modified Fractal
coding, the numbers of domain blocks are optimized from 343 to 10 using local search. Extensive
experiments are carried out on UCID - An Uncompressed Color Image Database. The proposed
approach minimizes the encoding process time because of optimized domain blocks and one
dimensional structure of Spiral Architecture and falls in the lossy compression category. The results
of SFC and our approach are compared with respect to the time.
