写一个图像处理阈值分割C++代码

Sure, here's a sample C code for threshold segmentation in image processing:
```
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#define IMG_SIZE 256 // image size
int main()
{
int image[IMG_SIZE][IMG_SIZE]; // input image
int threshold = 100; // threshold value
int i, j;
// read input image from file
FILE* fp = fopen("input_image.raw", "rb");
fread(image, sizeof(int), IMG_SIZE * IMG_SIZE, fp);
fclose(fp);
// threshold segmentation
for (i = 0; i < IMG_SIZE; i++) {
for (j = 0; j < IMG_SIZE; j++) {
if (image[i][j] > threshold) {
image[i][j] = 255;
} else {
image[i][j] = 0;
}
}
}
// save output image to file
fp = fopen("output_image.raw", "wb");
fwrite(image, sizeof(int), IMG_SIZE * IMG_SIZE, fp);
fclose(fp);
return 0;
}
```
Hope that helps!
