Image-retrieval

检测道路边缘，利用道路的平行线特性，来检测道路所在直线。(Detect edges of the road, the road parallel to the line features to detect the road where the straight line.)

标定投影仪与摄像机之间的透视变换矩阵，将摄像机图像转换成投影仪视角下的图像(calibration and transformation between camera and projector)

1.DCT变换，对整个图像的直接DCT变换和分块为8*8做DCT变换，并设定阈值。 2.汉明编码（7，4），译码以及找出错误图样和纠错。并在不同的转移概率的BSC道下进行传输。(DCT:Direct DCT and IDCT,blocking. hamming coding:decoding and picking up errors.)

形态学成分分析，该方法的基本思想是利用信号组成成分的形态差异，将图像分割为纹理和分片光滑部分。(Morphological Component Analysis，The basic point is that an image can be divided into texture and piecewise smooth parts by the morphological diversity among signal components.)

通过数字图像相关的方法计算两幅图像之间的位移，计算时间较长，是最基础的DIC，没有优化。(Digital image correlation method to calculate the displacement between the two images, the time is longer, is the most basic DIC, no optimization.)

对遥感图像进行无监督分类，形成决策树，实现地物的标定(Unsupervised classification of remote sensing images to form a decision tree, the calibration of surface features)

希尔伯特变换的matlab程序，用于在matlab中实现希尔伯特变换。(Hilbert transform matlab program )

图像融合程序，用以提取图像的高分辨率部分，实现图像的清晰化(image fusion procedure to extract high-resolution images, the images clearer)

说明：  Z源逆变器开路三相SVPWM调制，注入了三次谐波分量。(Open-circuit Three-phase SVPWM Modulation of Z-source Inverter)

sobel segmentation, this algorithme has a great effect for segmenting
