| 摘 要： | 针对含有噪声的数字图像去除相关性差的问题，鉴于数字图像的噪声模型，对图像作去噪处理后再用静态图像压缩标准JPEG基本系统作图像压缩编码。实验表明，该压缩方案具有较高信噪比、压缩比的良好性能。并且该方案具有推广的意义，可以应用到其他编码算法。用VC 6．0实现了该算法。

| Abstract: | It is aimed at the problem of impairing dependency of noised digital image, the paper gives an improvement of JPEG encoding compression: whereas noise model of dital image, coding the image with JPEGs basic system after weakening noise process of image. The experimental result shows that this compresion concept provides impressive performance: high signal-to-noise-ratio and compression-ratio. And also this scheme -noise elimination arithmetic based on noise model can be extended to other compression algorithm. |
