摘    要:阐述了JPEG2000图像压缩的实现过程,对其中的关键技术做了详细描述,并给出了在噪声环境下的试验结果。针对此过程,提出了一种基于小渡的消噪:采用二次平方损失函数,通过对待分析图像进行小波变换,在小渡变换域中,把小波系数进行闻值处理,即增强图像的小波系数,减弱或去除噪声的系数。计算机模拟实验结果表明:该方法能有效地消除噪声。

关 键 词:小波  图像压缩  消嗓

Abstract:The procedure of image compression and its key techniques are introduced; A detail experiment result is given. According to above, we put forward a denoising method based on wavelet: Quadratic Square Loss Function. Based on the wavelet transforming, we disposed the wavelet coefficient in the field of the wavelet transform that is strengthening the wavelet coefficient to the image and weakening the coefficient to the noise. After simulation experiment, it proved that this method is efficient to the image denoising.
Keywords:Wavelet  image compression  denoising
