#FRACTAL IMAGE COMPRESSION SOFTWARE FULL#
Download your Full Reports for Fractal Image Compression 1.1 A Brief History of Fractal Image Compression Jacquin, was the first to publish a similar fractal image compression scheme. The first public scheme was due to E.Jacobs and R.Boss of the Naval Ocean Systems Center in San Diego who used regular partitioning and classification of curve segments in order to compress random fractal curves (such as political boundaries) in two dimensions. This method is used on JPEG (still images), MPEG (motion video images), H.261 (Video Telephony on ISDN lines), and H.263 (Video Telephony on PSTN lines) compression algorithms.įractal Compression was first promoted by M.Barnsley, who founded a company based on fractal image compression technology but who has not released details of his scheme. The current most popular method relies on eliminating high frequency components of the signal by storing only the low frequency components (Discrete Cosine Transform Algorithm). The standard methods of image compression come in several varieties. An image can be changed in many ways that are either not detectable by the human eye or do not contribute to the degradation of the image. Most data contains some amount of redundancy, which can sometimes be removed for storage and replaced for recovery, but this redundancy does not lead to high compression ratios. These bits provide the ?yes? and ?no? answers to the 8 million questions that determine the image. Since the human eye can process large amounts of information (some 8 million bits), many pixels are required to store moderate quality images. Images are stored on computers as collections of bits (a bit is a binary unit of information which can answer ?yes? or ?no? questions) representing pixels or points forming the picture elements.

These facts justify the efforts, of private companies and universities, on new image compression algorithms. Storing images in less memory leads to a direct reduction in storage cost and faster data transmissions.
