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)

inexact_alm_rpca
RPCA (Robust Principal Component Analysis)是目前用于矩阵填充、图像去噪的最有效的优化方法。目前最有效的算法是ALM(Augmented Lagrange Multiplier)。ALM分为Exact ALM和Inexact ALM。 该代码是Inexact ALM,收敛速度比Exact ALM快!(RPCA (Robust Principal Component Analysis) is used for matrix filling, image denoising. It is currently the most effective optimization method. Currently the most effective method is ALM (Augmented Lagrange Multiplier). There re 2 kinds of ALM: Exact ALM and Inexact ALM. The code is Inexact ALM, faster convergence speed than the Exact ALM!)
