## Who invented fractal compression?

Michael Barnsley

Invented in the 1980s by Michael Barnsley and Alan Sloan, two mathematicians at Georgia Tech, fractal compression is based on the discovery by Benoit Mandelbrot, an IBM scientist, that a hidden geometry exists in apparently random patterns of nature.

**Who invented image compression?**

Nasir Ahmed

An important development in image data compression was the discrete cosine transform (DCT), a lossy compression technique first proposed by Nasir Ahmed in 1972. DCT compression became the basis for JPEG, which was introduced by the Joint Photographic Experts Group (JPEG) in 1992.

### What is the fundamental principle of fractal image compression?

Its beginnings date from the 1990s when Jacquin [17, 18] introduced the first method of image compression; its principle is partitioning the image into two tiling blocks: the range and domain blocks. The domain blocks are double the size of the range blocks and overlap such that a new domain block starts at each pixel.

**What is fractal image?**

Fractals are infinitely complex patterns that are self-similar across different scales. Driven by recursion, fractals are images of dynamic systems – the pictures of Chaos. Geometrically, they exist in between our familiar dimensions. Fractal patterns are extremely familiar, since nature is full of fractals.

#### Is fractal compression used?

Fractal image compression has been used in a number of commercial applications: onOne Software, developed under license from Iterated Systems Inc., Genuine Fractals 5 which is a Photoshop plugin capable of saving files in compressed FIF (Fractal Image Format).

**What are compressed images?**

Image compression is minimizing the size in bytes of a graphics file without degrading the quality of the image to an unacceptable level. The reduction in file size allows more images to be stored in a given amount of disk or memory space.

## Why is image compression used?

Image compression is an application of data compression that encodes the original image with few bits. The objective of image compression is to reduce the redundancy of the image and to store or transmit data in an efficient form.

**What are the two types of image compression?**

There are two main types of compression: lossy and lossless.

### How are fractals used in image compression?

Fractal compression is a lossy compression method for digital images, based on fractals. Fractal algorithms convert these parts into mathematical data called “fractal codes” which are used to recreate the encoded image.

**How does fractal compression work?**

To do fractal compression , the image is divided into sub-blocks. Then for each block , the most similiar block if found in a half size version of the image and stored. This is done for each block. Then during decompression, the opposite is done iteratively to recover the original image.

#### What is meant by fractal compression?

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.

**Why shall we do image compression at all?**

The objective of image compression is to reduce irrelevance and redundancy of the image data to be able to store or transmit data in an efficient form. It is concerned with minimizing the number of bits required to represent an image. Image compression may be lossy or lossless.

## What is fractal compression used for?

Fractal compression. 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.

**Who invented the fractal compression algorithm?**

Michael Barnsley led development of fractal compression in 1987, and was granted several patents on the technology. The most widely known practical fractal compression algorithm was invented by Barnsley and Alan Sloan.

### What happened to the fractal image format?

Iterated Systems Inc. supplied a shareware encoder (Fractal Imager), a stand-alone decoder, a Netscape plug-in decoder and a development package for use under Windows. As wavelet-based methods of image compression improved and were more easily licensed by commercial software vendors the adoption of the Fractal Image Format failed to evolve.

**Where can I use fiffractal image compression?**

Fractal image compression has been used in a number of commercial applications: onOne Software, developed under license from Iterated Systems Inc., Genuine Fractals 5 which is a Photoshop plugin capable of saving files in compressed FIF (Fractal Image Format).
