otsu
OTSU Gray-level image segmentation using Otsu s method.
Iseg = OTSU(I,n) computes a segmented image (Iseg) containing n classes
by means of Otsu s n-thresholding method (Otsu N, A Threshold Selection
Method from Gray-Level Histograms, IEEE Trans. Syst. Man Cybern.
9:62-66 1979). Thresholds are computed to maximize a separability
criterion of the resultant classes in gray levels.
OTSU(I) is equivalent to OTSU(I,2). By default, n=2 and the
corresponding Iseg is therefore a binary image. The pixel values for
Iseg are [0 1] if n=2, [0 0.5 1] if n=3, [0 0.333 0.666 1] if n=4, ...
[Iseg,sep] = OTSU(I,n) returns the value (sep) of the separability
criterion within the range [0 1]. Zero is obtained only with images
having less than n gray level, whereas one (optimal value) is obtained
only with n-valued images.

说明: 模型以永磁直驱同步发电机组为研究对象,对包括风力机、发电机及其控制系统等各部分进行控制建模与仿真,接着通过坐标变换,分析并网逆变器在d/q坐标系下的模型,采用基于d轴电网电压定向矢量控制,并通过前馈补偿,实现有功、无功的解藕独立控制.(The model takes the permanent magnet direct drive synchronous generator set as the research object, and carries on the control modeling and simulation to each part, including wind turbine, generator and its control system, and then analyzes the model of grid-connected inverter in d coordinate system through coordinate transformation. The voltage oriented vector control based on d-axis power network and feedforward compensation are adopted to realize the decoupling independent control of active and reactive power.)
