Image retrieval and indexing techniques are important for efficient management of visual database. Many techniques are generally developed based on the associated compression domain. In the fractal domain, a fractal code is a contractive affine mapping that represents a similarity relation between the range block and the domain block in an image. A new(More)
Digital image databases represent huge amount of data, automatic indexing and content base retrieval are crucial factors. IFS ( Iterated function system ) fractal code can be used to retrieve image and the position parameter of IFS code is replaced with the relative distance and direction parameter. A new algorithm of IFS fractal code for image retrieval on(More)
