摘要
提出一种基于Shannon熵标准的最优小波包基的图像去噪算法,并通过仿真验证其去噪效果要优于小波变换的去噪算法。
A new algorithm for denoising images based on optimal wavelet packet basis which adopts Shannon entropy is discussed. The simulation results show that this algorithm is better than algorithm for denoising images based on wavelet transform in denoising effect.
