九、OpenCV自带colormap

项目功能实现：每隔1500ms轮流自动播放不同风格图像显示，按下Esc键退出

按照之前的博文结构来，这里就不在赘述了

一、头文件

colormap.h

#pragma once
#include<opencv2/opencv.hpp>
using namespace cv;class ColorMap {
public:void color_map(Mat& image);
};

二、函数实现

colorsapces.cpp

#include"colormap.h"
#include<iostream>
#include<opencv2/opencv.hpp>void ColorMap::color_map(Mat& image) {int color_map[] = {COLORMAP_AUTUMN,COLORMAP_BONE,COLORMAP_CIVIDIS,COLORMAP_COOL,COLORMAP_DEEPGREEN,COLORMAP_HOT,COLORMAP_HSV,COLORMAP_INFERNO,COLORMAP_JET,COLORMAP_MAGMA,COLORMAP_OCEAN,COLORMAP_PARULA,COLORMAP_PINK,COLORMAP_PLASMA,COLORMAP_RAINBOW,COLORMAP_SPRING,COLORMAP_SUMMER,COLORMAP_TURBO,COLORMAP_TWILIGHT,COLORMAP_TWILIGHT_SHIFTED,COLORMAP_VIRIDIS,COLORMAP_WINTER};Mat result;int index = 0;while (true) {int key = waitKey(1500);if (key == 27) {//Escbreak;}applyColorMap(image, result, color_map[index % 21]);//这里有22种类型，循环播放index++;imshow("colormap", result);}}

三、主函数

yy_main.cpp

#include <opencv2/opencv.hpp>
#include <iostream>
#include "colormap.h"using namespace cv;
using namespace std;int main(int argc, char** argv) {Mat src = cv::imread("E:/C++_workspace/beyond.jpg", IMREAD_COLOR);if (src.empty()) {printf("load image is false...\n");return -1;}namedWindow("yanyu", WINDOW_FREERATIO);imshow("yanyu", src);ColorMap yy;yy.color_map(src);waitKey(0);destroyAllWindows();return 0;
}
