Fractal compression algorithm

Web3. Fractal Compression: This approach is based on the similarity of specific sections of a picture to other parts of the same image. This method transforms these elements into numerical data. Fractal codes are the data that is utilised to rebuild the encoded image. The image becomes resolution independent as it is turned into fractal code. 4. WebOct 1, 2013 · In this study, the performance of fractal-based coding algorithms such as standard fractal coding, quasi-lossless fractal coding and improved quasi-lossless fractal coding are evaluated by investigating their ability to compress magnetic resonance images (MRIs) based on compression ratio, peak signal-to-noise ratio and encoding time.

Fractal Image Compression and Its Techniques: A Review

Fractal compression is a lossy compression method for digital images, based on fractals. The method is best suited for textures and natural images, relying on the fact that parts of an image often resemble other parts of the same image.
