Due to high potential relativity of DCT coefficients and big compression performance of fractal, high compression rate of video data can be realized.

由于频域中dct系数的强相关性和分形的高压缩性能，能够实现视频数据的高压缩。

Then it introduces simply the present development of coding algorithms about arbitrary shape video object, and indicates the algorithms have a high compression rate.

然后简介了任意形状可视对象编码算法的研究现状，并指出此算法是一种产生高压缩比的图像压缩算法。

It has advantages of high compression rate, high compression speed, unchangeable signal and image characteristics after compression, and anti-interference under transmitting.

它的特点是压缩比高，压缩速度快，压缩后能保持信号与图像的特征不变，且在传递中可以抗干扰。
