An image registration matlab code

计算一副图像，或者加噪声后图像信噪比和峰值信噪比，代码非常简洁方便，效率很高。(Calculate the image SNR and PSNR)

说明：  计算视频或者图像中相邻两帧的光流场。 本光流场算法使用是 多项式展开的方法 配置好视频的路径之后，直接运行就可以了。(Calculation of video or image of two adjacent optical flow field. The optical flow algorithm using the polynomial method is a good video of the path configuration, the direct operation of it.)

车型识别图像处理MATLAB代码可运行适合新手入门只用(car recognization adapted rookie study playplay)

说明：  基于LBP纹理特征的运动目标检测算法.rar(Moving target detection algorithm based on LBP texture features. Rar)

实现了对误拍角度的矫正，基于轮廓提取以及旋转矩阵变换实现图像错误识别和矫正(It realizes the correction of misalignment angle, and realizes image error recognition and correction based on contour extraction and rotation matrix transformation.)

matlab编写Zernike多项式拟合横向剪切波前重建。(matlab write Zernike polynomial fitting transverse shear wave before reconstruction.)

按照夹角余弦距离计算待测样品与样品库的样品相似度(Cosine distance calculation in accordance with the test sample and the sample database sample similarity)

通过将三维图像投影成2维ddr图像来实现2D-3D图像配准(By three-dimensional image projection into 2-D images ddr to achieve 2D-3D Image Registration)

主动轮廓模型也就是snake模型进行图像分割，一种由图像高层信息的图像分割算法。(snake model，active contour model，image segmentation)
