OpenCV之边缘保留滤波算法 – 均值迁移模糊(mean-shift blur)

Posted 2021-08-16 MachineLP

python代码：

import cv2 as cv
import numpy as np

src = cv.imread("./test.png")
cv.namedWindow("input", cv.WINDOW_AUTOSIZE)
cv.imshow("input", src)

h, w = src.shape[:2]
dst = cv.pyrMeanShiftFiltering(src, 15, 30, termcrit=(cv.TERM_CRITERIA_MAX_ITER+cv.TERM_CRITERIA_EPS, 5, 1))
result = np.zeros([h, w*2, 3], dtype=src.dtype)
result[0:h,0:w,:] = src
result[0:h,w:2*w,:] = dst
result = cv.resize(result,(w, h//2))
cv.imshow("result", result)
# cv.imwrite("result.png", result)

cv.waitKey(0)
cv.destroyAllWindows()

C++代码：

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

using namespace cv;
using namespace std;

int main(int artc, char** argv) {
	Mat src = imread("./test.png");
	if (src.empty
