用c语言改写import cv2 import numpy as np #读取原始图像 img = cv2.imread('scenery.png', 1) #获取图像的高度和宽度 height, width = img.shape[:2] #图像灰度处理 gray = cv2.cvtColor(img,cv2.COLOR_BGR2GRAY) #创建目标图像 dstImg = np.zeros((height,width,1),np.uint8) #浮雕特效算法：newPixel = grayCurrentPixel - grayNextPixel + 150 for i in range(0,height): for j in range(0,width-1): grayCurrentPixel = int(gray[i,j]) grayNextPixel = int(gray[i,j+1]) newPixel = grayCurrentPixel - grayNextPixel + 150 if newPixel > 255: newPixel = 255 if newPixel < 0: newPixel = 0 dstImg[i,j] = newPixel #显示图像 cv2.imshow('src', img) cv2.imshow('dst',dstImg) #等待显示 cv2.waitKey() cv2.destroyAllWindows()

以下是使用C语言改写后的代码：

#include <stdio.h>
#include <stdlib.h>
#include <opencv2/opencv.hpp>

using namespace cv;

int main(int argc, char** argv)
{
    //读取原始图像
    Mat img = imread("scenery.png", IMREAD_COLOR);
    if (img.empty())
    {
        printf("Could not read the image: %s\n", argv[1]);
        return -1;
    }

    //获取图像的高度和宽度
    int height = img.rows;
    int width = img.cols;

    //图像灰度处理
    Mat gray;
    cvtColor(img, gray, COLOR_BGR2GRAY);

    //创建目标图像
    Mat dstImg(height, width, CV_8UC1);

    //浮雕特效算法：newPixel = grayCurrentPixel - grayNextPixel + 150
    for (int i = 0; i < height; i++)
    {
        for (int j = 0; j < width - 1; j++)
        {
            int grayCurrentPixel = (int)gray.at<uchar>(i, j);
            int grayNextPixel = (int)gray.at<uchar>(i, j + 1);
            int newPixel = grayCurrentPixel - grayNextPixel + 150;
            if (newPixel > 255)
            {
                newPixel = 255;
            }
            if (newPixel < 0)
            {
                newPixel = 0;
            }
            dstImg.at<uchar>(i, j) = (uchar)newPixel;
        }
    }

    //显示图像
    namedWindow("src", WINDOW_AUTOSIZE);
    namedWindow("dst", WINDOW_AUTOSIZE);
    imshow("src", img);
    imshow("dst", dstImg);

    //等待显示
    waitKey(0);
    destroyAllWindows();

    return 0;
}

注意：在使用该代码之前，需要先安装OpenCV库，并确保编译器能够正确链接该库。
