Description: 对于运动图像分析菜单的一点说明
该菜单为主框架里的一个菜单项，对应第九章运动分析内容，该菜单提供了两种分析方法，提供的两幅静态图像为随书光盘所带“各章测试图”中“第九章”文件夹内的“图9-5a.bmp”和“图9-5b.bmp”。
归一化相位相关方法和相位差方法是两种运动估计方法，根据算法原理的不同，其输出形式也不相同。
例如，对于所提供的128*128大小的一对测试图，相位差的方法输出形式为：“相对于第一幅图像，x方向移动1像素，y方向移动3像素” ，其含义是相对于第一幅图像，第二幅图像在x正方向有1个像素的位移，在y方向有3个像素的位移。
而相位相关方法以图像中心为基准。例如，相位相关输出为“相对于第一幅图像，x方向移动为63个像素，y方向移动为66个像素”，代表中心在x方向移动1个像素，在y方向移动了3个像素。其运动方向不能根据结果的正负号判断
-For the analysis of moving images that explain the menu
The menu-based framework of a menu item, the corresponding movement of the contents of Chapter IX, the menu offers two analysis methods, providing the two still images brought to CD with the book, "each chapter test pattern" in the "Ninth chapter "in the folder" Figure 9-5a.bmp "and" Figure 9-5b.bmp ".
Normalized phase correlation method and the phase difference of two motion estimation methods is, according to the principle of different algorithms, the output is not the same form.
For example, provide a 128* 128 size of the test chart, form the output phase approach: "relative to the first image, x 1 pixel direction, y direction by 3 pixels", its meaning is relative to the the first image, the second image in the x direction is 1 pixel displacement, in the y direction of the displacement of 3 pixels.
The phase correlation method to the image center as the base. For example, the phase correlation output is "relative to the Platform: |
