说明: 边缘特征的提取就是求图像梯度的局部最大值和方向。实际计算中,以微分算子的形式表示,并采用快速卷积函数来实现。常用的算子有微分算子,拉普拉斯算子,Canny算子等。其中Canny边缘检测是一种较新的边缘检测算子,具有较好的边缘检测性能,得到越来越广泛的应用。Canny边缘检测法利用高斯函数的一阶微分,它能在噪声抑制和边缘检测之间取得较好的平衡(Edge feature extraction is to seek the local maximum of image gradient and orientation. The actual calculation to the form of differential operator representation, and using fast convolution function to achieve. Commonly used operators are differential operators, Laplace operator, Canny operator and so on. Canny edge detection which is a relatively new edge detection operator, and has good edge detection performance, get more and more widely used. Canny edge detection method using first derivative of Gaussian function, it can in the noise suppression and edge detection to achieve a better balance between)

提出了一种基于非下采样Contourlet 变换的自适应图像去噪方法 首先对噪声图像进行非下采样Contourlet 变换,得到各
个尺度各个方向子带的系数,再根据该系数的能量自适应地调整去噪阈值 实验表明,与Contourlet 多尺度阈值去噪 Contourlet 自
适应阈值去噪相比,该方法在保留图像边缘细节的同时,能提高图像的PSNR 值,减少了Gibbs 现象(A new adaptive method of image de-noising based on NonSubsampled Contourlet Transform (NSCT)is presented.Firstly,
the noisy image is decomposed into a set of multiscale and multidirectional frequency subbands by NSCT, and then the threshold
is adapted automatically according to the energy of subband coefficients.Compared with the multi-scale threshold using contourlet
transform and using adaptive threshold based on contourlet transform, the simulation results show that the performance of this
method is superior in PSNR, meanwhile it can maintain the image edge and reduce the Gibbs phenomen)
