快速傅立叶变换的图像数据压缩算法

当今图像数据信息的海量化,使得图像压缩编码应用显得尤为重要,图像压缩的分类方法很多,限失真编码以其压缩比高而得到广泛应用。常见的限失真编码主要采用余弦变换,K-L变换,小波变换等。该文另辟蹊径采用快速傅里叶变换,及霍夫曼编码方式对标准lena图像数据进行限失真压缩编码压缩,得到了较好的压缩效果。

The Algorithm with Image Data Compression of FFT

On the current,the overwhelming amount information of the image data, making the application of image compression coding is becoming more and more particularly important. In the many classification of image compression Algorithms, compression ratio distortion coding has been widely used. Limited common distortion mainly cosine transform coding, K-L transform, wavelet transform and so on. In this paper, open a new path using fast Fourier transform, and Huffman encoding standard limited lena image data compre...
