【Opencv&Cpp】08 滤镜也就这么简单：颜色表

colormap

applyColorMap

applyColorMap函数

 applyColorMap（输入，输出，风格）

 applyColorMap（image，dst，colormap_cool） 

遍历展示一下风格

//颜色表
	int colormap[] = {
		COLORMAP_AUTUMN,
		COLORMAP_BONE,
		COLORMAP_JET,
		COLORMAP_WINTER,
		COLORMAP_RAINBOW,
		COLORMAP_OCEAN,
		COLORMAP_SUMMER,
		COLORMAP_SPRING,
		COLORMAP_COOL,
		COLORMAP_PINK,
		COLORMAP_HOT,
		COLORMAP_PARULA,
		COLORMAP_MAGMA,
		COLORMAP_INFERNO,
		COLORMAP_PLASMA,
		COLORMAP_VIRIDIS,
		COLORMAP_CIVIDIS,
		COLORMAP_TWILIGHT,
		COLORMAP_TWILIGHT_SHIFTED
	};
	imshow("原图", image);
	Mat dst;
	int index = 0;
	while(1) {
		int c = waitKey(500);
		if (c == 27) { // 退出
			break;
		}
		applyColorMap(image, dst, colormap[index % 19]);
		cout << "目前为" << colormap[index % 19] <<"号风格" << endl;
		index++;
		imshow("颜色风格", dst);
	}
