【摘要】 小波图象去噪是目前图象去噪的主要方法之一,它可以在很好去除噪声的前提下保持图象的细节特征。近年来基于偏微分方程的图象去噪方法得到了广泛的关注。在一定的约束条件下,求解方程的最优解可以达到比较好的去噪的目的。实验结果表明,该方法在图象去噪的效果上要比小波去噪好,去噪后图象的信噪比高。更多还原

【Abstract】 Wavelet image denoising is regarded as an important method of image denosing,which can preserve the image features.Presently,the image denoising method based on partial differential equations attracts people’s attentin.The optimization result of equation with some constrains can denoise perfectly.Compared with wavelet denoising,the paper concludes that the method based on partial differential equations is more better,and with high SNR.更多还原
