图像分割，二维图像分割，ostu算法，阈值分割(Segmentation, two-dimensional image segmentation, ostu algorithm, thresholding)

用经验模式分解分解出固有模式函数，从而得出瞬时频率和包络，适合进行特征提取(using empirical mode decomposition decomposition patterns inherent function, thereby reaching and instantaneous frequency envelope, suitable for feature extraction)

压缩感知中利用增广拉格朗日方程解最小稀疏正则化的恢复算法(DAL solves the dual problem of (1) via the augmented Lagrangian method (see Bertsekas 82). It uses the analytic expression (and its derivatives) of the following soft-thresholding operation， which can be computed for L1 and grouped L1 (and many other) sparsity inducing regularizers. If you are interested in our algorithm please find more details in our technical report or in my talk at Optimization for Machine Learning Workshop (NIPS 2009).)
