说明：  Hu的七个不变矩在图像匹配检索中适用广泛。本代码仅计算图像间Hu的七个矩的D2大小，直观的了解Hu矩的应用(seven moment invariants in image retrieval in the application of broad match. Only the calculation of the code between the image of the seven Hu moments D2 size, intuitive understanding of the application of Hu Moment)

SIFT，即尺度不变特征变换（Scale-invariant feature transform，SIFT），是用于图像处理领域的一种描述。这种描述具有尺度不变性，可在图像中检测出关键点，是一种局部特征描述子。[1] 该方法于1999年由David Lowe[2] 首先发表于计算机视觉国际会议（International Conference on Computer Vision，ICCV），2004年再次经David Lowe整理完善后发表于International journal of computer vision（IJCV）。截止2014年8月，该论文单篇被引次数达25000余次。(SIFT, namely Scale Invariant Feature Transform (Scale-invariant feature transform, SIFT), it is a description for image processing. This description has scale invariance, can detect critical point in the image, it is a local feature descriptor. [1] The method in 1999 by David Lowe [2] First published in the International Conference on Computer Vision (International Conference on Computer Vision, ICCV), 2004 was again perfect finishing after David Lowe published in the International journal of computer vision (IJCV) . As of August 2014, the paper cited the number of times a single article of more than 25,000 times.)

说明：  用canny算子来检测图像边缘，VC++(Using canny operator to detect image edge)

用于图像分割，基于fcm算法的图像分割，实现模糊均值聚类的分割，更准却的实现分割。(For image segmentation, image segmentation based on FCM algorithm, the realization of fuzzy clustering segmentation, more accurate but to achieve segmentation.)

剪切波是小波变换的一种，常用于增强或者去噪，本代码用于去除图像噪声(The shear wave is a wavelet transform, often used to enhance or de-noising, the code is used to remove the image noise)

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.)

图像处理基础、图像运算、图像编码、图像变换、图像增强、图像复原、图像的分割、图像数学形态学处理和小波图像处理(The basis of image processing, image computing, image coding, image transformation, image enhancement, image restoration, image segmentation, image mathematical morphology and wavelet image processing)

hsv的空间量化，要求输入为hsv空间中的图像。分别对h、s、v三个分量进行量化。(hsv space quantization, for admission to hsv space images. Respectively h, s, v 3 components quantified.)

Ransac拟合直线和最小二乘法拟合的比较，对初次接触ransac的读者帮助很大(Ransac fitting straight line and the least-squares fitting of the comparison, the initial contact with the readers of great help to ransac)
