Image compression is a method through which we can reduce the storage space of images, videos which will helpful to increase storage and transmission process’s performance, Images are compressed using lossy and Lossless compression schemes. In this paper Fractal image compression is discussed .Fractal image compression is a lossy compression method for digital images, based on fractals. The met...

In this paper, fractal monochrome image compression technique proposed by Jacquin is investigated for 24-bit true color image by encoding the RGB components' images independently. To exploit the spectral redundancy in RGB components, the root mean square error distortion measure in grayscale space is extended to 3-dimensional color space for fractal-based color image coding. Experimental result...

Fractal Video Compression (FVC) is of extensive interest for over 20 years. Instead of being implemented on square image structure, Spiral Architecture (SA) based fractal image compression is proposed in this paper to illustrate the great potential of FVC on SA. Conceptually, a new definition of range block and domain block is presented on this enhanced image structure. Compared with the conven...

Fractal approach is successfully implemented in many applications within 2D signal processing. Fractal synthetical concept is applied for image compression with high compression ratios while fractal and multifractal descriptors provide classification of textural images with high occuracy. Various multifractal models are presented in literature. This paper summarizes them and illustrates new mul...

In content-based image retrieval system, describing and extracting image’s feature is a key question. An image can be characterized by its fractal codes, and fractal codes can be used as the image’s feature to retrieve the images effectively. This paper proposes a novel image retrieval method using information entropy and fractal coding. First, each image in the database is classified by comput...

There is a considerable amount of literature about image denoising using wavelet-based methods. Some new ideas where also reported using fractal methods. In this paper we propose a hybrid wavelet-fractal denoising method. Using a non-subsampled overcomplete wavelet transform we present the image as a collection of translation invariant copies in different frequency subbands. Within this multipl...

In this paper, the basic theory of image fractal compression is briefly introduced; some typical fractal compression approaches are discussed. Based on this discussion, according to the problem of long encoding time which exists in the typical fractal compression approaches, we propose a fast image fractal compression approach based on the combination of adaptive quad tree compression approach ...
