Fractal Image Coding: A New Approach with Block Merging
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2012, Vol 2, Issue 4
Abstract
The most of the fractal coding schemes proposed so far are based on Iterated Function Systems, Range block and domain blocks partition. In this paper, a scheme is proposed which is based on searching the blocks in image that have some common information and then after finding such block we make major block to hold or store a large amount of data in small space. In this scheme, the range blocks are made by searching and merging method. Here we define two types of major blocks, dark blocks and non-dark blocks, according to the different brightness level inside blocks. These major blocks of different types are extracted from the input image. These major blocks leads to the reduction in smaller primary blocks and making larger major blocks and also result in reduction of encoded bits.
