代码说明:

  图像的傅里叶变换。在代码中实现了将两幅图像的幅度谱和相位谱进行交换,进而理解两者在图像显示中的作用(Fourier transform of the image. Implemented in the code will be two images amplitude spectrum and phase spectrum of exchange, and thus to understand both the role of the image display)

  • BMP_pix_read_write
    实现BMP文件的基本功能。用C++实现一个Class,该Class具有读写BMP文件功能;该Class还具有对图像像素进行操作的功能(针对每个像素的读、写) (BMP files to achieve the basic functions. Using C++ implementation of a Class, the Class has read and write BMP file functions the Class also features the image pixel operation function (for each pixel of the read, write))

  • Key_Technology_for_Image_Mosaics-
    提出一种基于特征点的运动场景图像拼接算法。基于相似变换消除选取在运动物体上的特征点,并使用RANSAC算法进行外点的剔除。在融合阶段,根据齐次变换矩阵求得对2幅图像的差异图像,并执行区域增长算法。从而分割出运动区域。使用一种分段映射算法生成全景图像。实验证明了算法的有效性。(A feature-based algorithm for image mosaics of 8c宅Iles with moving objects is pI.oposcd.The algorithm eliminates the feature points which arc selected in moving objects using similarity transform,and the outliers are eliminated using RANSAC algorithm.In the image blend phase,a difference of two images is created using homogeneous transformation matrix,and a region growth algorithm is implemented SO as to segment the movmg object region.A piecewise mapping algorithm for generating panoramic images is used.Experimental results show the effectiveness of the algorithm.)
