摘要
根据一维方向数组的小波变换消噪较好地保留方向性边缘细节的特性,提出从水平、垂直、对角线四个方向将二维图像转化为一维数组进行去噪研究的算法。实验结果表明,该算法同文献[5]及二维图像软阈值消噪处理相比,具有更好的去噪和保留边缘细节能力。
According to the character of the 1D wavelet transform which has good edge preservation ability, a de-noise algorithm is proposed,which changes the 2D image into 1D array to remove noise from horizontal , vertical ,and diagonal direction .The experiment results show that this method is superior to the reference^([5]) and De-noising by soft thresholding in the respect of noise removal and edge preservation .
