摘要

多年来,对多媒体应用程序的需求不断增加。由于这个问题,图像和视频压缩成为减少时间和数据存储的关键问题。分形图像压缩(FIC)是一种产生损失的压缩技术,可以进行大量的压缩。该方案通过将图像分类为块并使用压缩映射来工作。FICs的一些优点可以表现为:与其他标准压缩技术相比,它在PNSR和压缩比之间有很好的互换性,并且由于其与分辨率无关的特性,它可以在不降低图像质量的情况下对图像进行缩放。FICs的主要缺点是编码复杂,速度慢。

Optimal Management of the Multimedia Application
The need for multimedia applications has increased over the years. Due to this issue, image and video compression becoming an essential problem in reducing time and data storage. Fractal Image Compression (FIC) is a compression technique which results in loss, and we can have large amounts of compression. This scheme works by classifying an image into blocks and uses Contractive Mapping. Some of FICs advantages can be expressed as follows: comparing with other standard compression techniques, it has a good interchange between PNSR and compression ratio and it zooms the image without reducing the quality due to its resolution independent nature. The main FICs drawback, is its complexity in encoding and lack of speed.
