多帧图像融合一般需要以下步骤:
1. 读取多张图片并将它们转换成相同大小的矩阵
2. 对每个像素点进行颜色值的加权平均
3. 将所有像素点的平均值组成新的矩阵
以下是一个简单的多帧图像融合的 C 代码实现:
```c
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define MAX_NUM_IMAGES 10
#define MAX_FILENAME_LENGTH 256
int main(int argc, char* argv[])
{
int num_images;
char filenames[MAX_NUM_IMAGES][MAX_FILENAME_LENGTH];
int width, height;
// 读取命令行参数
if (argc < 4) {
printf("Usage: %s <num_images> <width> <height> <filename1> <filename2> ...\n", argv[0]);
return 1;
}
num_images = atoi(argv[1]);
width = atoi(argv[2]);
height = atoi(argv[3]);
if (num_images > MAX_NUM_IMAGES) {
printf("Maximum number of images allowed is %d\n", MAX_NUM_IMAGES);
return 1;
}
if (argc != num_images + 4) {
printf("Number of filenames doesn't match the specified number of images\n");
return 1;
}
for (int i = 0; i < num_images; i++) {
strncpy(filenames[i], argv[i + 4], MAX_FILENAME_LENGTH);
}
// 分配内存空间
unsigned char* image_data = (unsigned char*) malloc(num_images * width * height);
// 读取图像数据
for (int i = 0; i < num_images; i++) {
FILE* fp = fopen(filenames[i], "rb");
fread(image_data + i * width * height, 1, width * height, fp);
fclose(fp);
}
// 计算平均值
unsigned char* average_image_data = (unsigned char*) malloc(width * height);
memset(average_image_data, 0, width * height);
for (int i = 0; i < num_images; i++) {
for (int j = 0; j < width * height; j++) {
average_image_data[j] += image_data[i * width * height + j] / num_images;
}
}
// 保存结果
FILE* fp = fopen("average_image.raw", "wb");
fwrite(average_image_data, 1, width * height, fp);
fclose(fp);
// 释放内存空间
free(image_data);
free(average_image_data);
return 0;
}
```
这个代码可以从命令行接收多张图片的路径,并输出它们的平均值。它假设所有图像都是灰度图像,并且已经按照相同的大小调整过。如果需要处理彩色图像或者不同大小的图像,需要对代码进行修改。
