在C / C旋转图像++ [英] Rotating an image in C/C++

问题描述

我需要code旋转在C ++中的图像，功能和MATLAB的imrotate功能。
请提出一个很好的链接。或者，如果有人能提供code为imrotate。

I need code for rotating an image in C++ which functions like imrotate function of matlab. Please suggest a good link. Or if someone can provide the code for imrotate.

或者至少请解释的算法。

Or at least please explain the algorithm.

它不是一门功课。我需要这个code为我的项目。我们可以使用任何外部库或code。

Its not a homework. I need this code for my project. And we can use any external library or code.

推荐答案

<一个href=\"http://sourceforge.net/projects/opencvlibrary/files/opencv-win/2.0/OpenCV-2.0.0a-win32.exe/download\">OpenCV2.0有几个计算机视觉和图像处理工具。具体来说<一个href=\"http://opencv.willowgarage.com/documentation/cpp/geometric_image_transformations.html?highlight=warp#warpAffine\">warpAffine （通过定义旋转矩阵），将解决你的问题，旋转图像。

OpenCV2.0 has several computer vision and image processing tools. Specifically warpAffine (by defining the rotation matrix) will solve your problem with rotating an image.

在文档中提到的2×3变换矩阵如下：

The 2x3 transformation matrix mentioned in the documentation is as follows:

其中θ是旋转的角度和T _X 和T _是沿翻译的 X 的和的是分别轴。

where θ is the angle of rotation and t_x and t_y is the translation along the x and y axes respectively.

您可以在这里得到源$ C ​​$ C 。​​

You can get the source code here.

此外，OpenCV2.0拥有的许多的MATLAB式的功能，如 imread 等

Also, OpenCV2.0 has many MATLAB-esque functions like imread, etc.
