该算法实现字母个数的统计,希望对大家有用!()

level set分割算法的matlab实现,by Chunming Li(image segmentation based on level sets algorithm.composed by Chunming Li)

说明：  包含多个函数，可直接调用（需按注释输入参数），对ppm和pgm文件，读、写和多种图像处理。(Ppm and pgm file for reading and writing, and various image processing)

完成了对光伏发电并网控制的设计及仿真。系统采用了两级式拓扑结构：前级用直流变换器进行最大功率跟踪及直流母线电压调整；后级用逆变器将直流电能逆变送入电网。(Completed the design and simulation of photovoltaic grid-connected control. The system adopts a two-stage topology: the front stage uses a DC converter for maximum power tracking and DC bus voltage adjustment; the latter stage uses an inverter to send DC power into the grid.)

本文件中代码使用前馈卷积神经网络对图像进行去噪(In this paper, we use the feedforward convolution neural network to denoise the image.)

本代码主要给出了激光粒度仪颗粒散射光强分布以及4种粒度反演算法，以及4种算法之间的比较。四种反演算法为：TSVD、Chaine、Tikhonov和l1正则化。(The code gives the Zetasizer particle scattering intensity distribution, and four kinds of particle inversion algorithm, as well as a comparison between the four algorithms. Four kinds of inversion algorithm is: TSVD, Chaine, Tikhonov and l1 regularization.)

Matlab图像处理中的Harris角点提取算法， 代码中有详细的解说，方便阅读。 (Matlab Image Processing of Harris corner extraction algorithm, the code has a detailed explanation, easy reading.)

利用matlab，对图像进行高斯滤波，然后通过非极大值抑制，设置双阈值，实现图像边缘检测(Image edge detection)

实现了geodesic active contour图像分割算法，用到AOS scheme and level set method(Realize the geodesic active contour image segmentation algorithm, using AOS scheme and level set method)

说明：  两种基于非下采样变换图像去噪方法，效果比contourlet变换要好(Two transform based image denoising nonsubsampled method, the effect is better than contourlet transform)
