Image sparse representation data got by sparse decomposition method are compressed by quantization and coding.
在图像稀疏分解的基础上,对分解出的数据进行压缩。
Fractal Image-compressed is carried out after DWT or DCT to improve coding speed and get higher CR and PSNR, but quality of reconstructed-Image is not satisfactory.
运用小波域及DCT域下的分形压缩图像方法,提高了编码速度,得到较高的压缩比和信噪比,但重构图像质量还存在块状效应。
