算法描述
OpenCV 中应用类似于 GNU Octave 或 MATLAB 中的颜色映射虽然 OpenCV 中的颜色映射类型与 GNU Octave 或 MATLAB 中的颜色映射类型名称不完全相同但它们在功能上是类似的。
函数原型
void cv::applyColorMap
(InputArray src,OutputArray dst,int colormap
) 参数
参数src 源图像灰度或彩色类型为 CV_8UC1 或 CV_8UC3。参数dst 结果是带有颜色映射的源图像。注意Mat::create 会在 dst 上被调用。参数colormap T要应用的颜色映射参见颜色映射类型ColormapTypes。
代码示例 #include iostream
#include opencv2/opencv.hppint main( int argc, char** argv )
{// 加载灰度图像cv::Mat grayImage cv::imread( /media/dingxin/data/study/OpenCV/sources/images/qiu.jpg, cv::IMREAD_GRAYSCALE );if ( grayImage.empty() ){std::cerr Error: Image cannot be loaded! std::endl;return -1;}// 创建一个空的 Mat 对象来保存彩色图像cv::Mat colorImage;cv::imshow( Original Gray Image, grayImage );cv::applyColorMap( grayImage, colorImage, cv::COLORMAP_JET );cv::imshow( Colored Image COLORMAP_JET, colorImage );cv::applyColorMap( grayImage, colorImage, cv::COLORMAP_BONE );cv::imshow( Colored Image COLORMAP_BONE, colorImage );cv::applyColorMap( grayImage, colorImage, cv::COLORMAP_HOT );cv::imshow( Colored Image COLORMAP_HOT, colorImage );cv::applyColorMap( grayImage, colorImage, cv::COLORMAP_COOL );cv::imshow( Colored Image COLORMAP_COOL, colorImage );cv::applyColorMap( grayImage, colorImage, cv::COLORMAP_SPRING );cv::imshow( Colored Image COLORMAP_SPRING, colorImage );cv::applyColorMap( grayImage, colorImage, cv::COLORMAP_SUMMER );cv::imshow( Colored Image COLORMAP_SUMMER, colorImage );cv::applyColorMap( grayImage, colorImage, cv::COLORMAP_AUTUMN );cv::imshow( Colored Image COLORMAP_AUTUMN, colorImage );cv::applyColorMap( grayImage, colorImage, cv::COLORMAP_WINTER );cv::imshow( Colored Image COLORMAP_WINTER, colorImage );cv::waitKey( 0 );return 0;
}运行结果
