OpenCV之图像伪彩色增强

Posted 2021-08-13 MachineLP

python代码：

import cv2 as cv

src = cv.imread("test1.png")
cv.namedWindow("input", cv.WINDOW_AUTOSIZE)
cv.imshow("input", src)
dst = cv.applyColorMap(src, cv.COLORMAP_COOL)
cv.imshow("output", dst)

# 伪色彩
image = cv.imread("test0.jpg")
color_image = cv.applyColorMap(image, cv.COLORMAP_JET)
cv.imshow("image", image)
cv.imshow("color_image", color_image)
cv.waitKey(0)
cv.destroyAllWindows()

C++代码：

#include <opencv2/opencv.hpp>
#include <iostream>

using namespace cv;
using namespace std;
void customColorMap(Mat &image);
int main(int argc, const char *argv[])
{
	Mat src = imread("cos.jpg");
	if (src.empty())
	{
		printf("could not load image...\\n");
		return -1;
	}
	Mat gray, dst;
	// ʹ�&
