写一段Web前端配置图像处理参数代码与后端Cpp图像处理交互的代码

Web前端配置图像处理参数代码:
```javascript
let config = {
resize: {
width: 800,
height: 600
},
grayscale: true,
blur: 5
};
let params = new URLSearchParams(config);
fetch('/image-process', {
method: 'POST',
body: params.toString(),
headers: {
'Content-Type': 'application/x-www-form-urlencoded'
}
}).then(response => {
// 处理返回的图像
});
```
后端Cpp图像处理交互的代码:
```cpp
#include <iostream>
#include <cstdlib>
#include <cstdio>
#include <cstring>
#include <string>
#include <cstdint>
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;
int main(int argc, char** argv)
{
// 解析参数
int width = 0, height = 0, blur = 0;
bool grayscale = false;
for (int i = 1; i < argc; i += 2) {
if (strcmp(argv[i], "--resize") == 0) {
sscanf(argv[i+1], "%dx%d", &width, &height);
} else if (strcmp(argv[i], "--grayscale") == 0) {
grayscale = true;
} else if (strcmp(argv[i], "--blur") == 0) {
blur = atoi(argv[i+1]);
}
}
// 读取图像
Mat image = imread("image.jpg");
// 处理图像
if (grayscale) {
cvtColor(image, image, COLOR_BGR2GRAY);
}
if (width > 0 && height > 0) {
resize(image, image, Size(width, height));
}
if (blur > 0) {
GaussianBlur(image, image, Size(blur, blur), 0);
}
// 输出图像
imwrite("processed_image.jpg", image);
return 0;
}
```
通过解析前端传来的参数,后端根据参数对图像进行处理,最终将处理后的图像输出。
