An Improved Robust Fractal Image Compression Based on M-Estimator
In this paper, a robust fractal image compression method based on M-estimator is presented. The proposed method applies the M-estimator to the parameter estimation in the fractal encoding procedure using Huber and Tukey’s robust statistics.

Digital Video Compression Using DCT-Based Iterated Function System (IFS)
Large video files processing involves a huge volume of data. The codec, storage systems and network needs resource utilization, so it becomes important to minimize the used memory space and time to distribute these videos over the Internet using ...

Region-based fractal image compression [PDF]
A fractal coder partitions an image into blocks that are coded via self-references to other parts of the image itself. We present a fractal coder that derives highly image-adaptive partitions and corresponding fractal codes in a time-efficient manner using a region-merging approach.

Fractal-Based Image Encoding and Compression Techniques
In computer science and information theory, data compression, source coding, or bit-rate reduction is the process of encoding digital information using fewer bits than the original representation.

Evolutionary fractal image compression [PDF]
This paper introduces evolutionary computing to fractal image compression. In fractal image compression a partitioning of the image into ranges is required. We propose to use evolutionary computing to find good partitionings. Here ranges are connected sets of small square image blocks.

FRACTAL COMPRESSION TECHNIQUE FOR COLOR IMAGES USING VARIABLE BLOCK
The main intention of Fractal Image Compression is to reduce the size of image and maintain good level of their reconstructed image. A major issue in Fractal Image Compression is decrease in image quality, compression ratio and PSNR.

Fractals: An Eclectic Survey, Part II
Fractals are geometric shapes and patterns that can describe the roughness (or irregularity) present in almost every object in nature. Many fractals may repeat their geometry at smaller or larger scales.

Fractal image compression algorithm is known for allowing very high compression rates (the best examples – up to 1 000 times with acceptable visual quality) for real photos of natural objects, which is not possible for other lossy compression methods ...

A Review on Block Matching Motion Estimation and Automata Theory based Approaches for Fractal Coding
Fractal compression is the lossy compression technique in the field of gray/color image and video compression. It gives high compression ratio, better image quality with fast decoding time but improvement in encoding time is a challenge.
