好的,以下是一个C++实现的8链码描述和循环首差链码计算的代码:
```c++
#include <iostream>
#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;
// 8链码
const int CHAIN_CODE[] = {0, 1, 2, 3, 4, 5, 6, 7};
// 找到图像的起始点
Point get_start_point(Mat img) {
for (int i = 0; i < img.rows; i++) {
for (int j = 0; j < img.cols; j++) {
if (img.at<uchar>(i, j) > 0) {
return Point(j, i);
}
}
}
return Point(0, 0);
}
// 计算图像的8链码
vector<int> get_chain_code(Mat img) {
Point current_point = get_start_point(img);
vector<int> chain_code;
int last_code = 0;
while (true) {
int x = current_point.x;
int y = current_point.y;
for (int i = 0; i < 8; i++) {
int j = (last_code + i) % 8;
int new_x = x + round(sin(M_PI * j / 4));
int new_y = y + round(cos(M_PI * j / 4));
if (new_x >= 0 && new_x < img.cols && new_y >= 0 && new_y < img.rows && img.at<uchar>(new_y, new_x) > 0) {
chain_code.push_back(j);
current_point = Point(new_x, new_y);
last_code = j;
break;
}
}
if (current_point == get_start_point(img) && last_code == chain_code[0]) {
break;
}
}
return chain_code;
}
// 计算循环首差链码
vector<int> get_circular_shifted_chain_code(vector<int> chain_code) {
vector<int> circular_shifted_chain_code;
for (int i = 0; i < chain_code.size(); i++) {
circular_shifted_chain_code.push_back((chain_code[i] - chain_code[0] + 8) % 8);
}
return circular_shifted_chain_code;
}
int main() {
// 读取二值图像
Mat img = imread("binary_image.png", IMREAD_GRAYSCALE);
threshold(img, img, 127, 255, THRESH_BINARY);
// 计算8链码
vector<int> chain_code = get_chain_code(img);
cout << "8链码:";
for (int i = 0; i < chain_code.size(); i++) {
cout << chain_code[i] << " ";
}
cout << endl;
// 计算循环首差链码
vector<int> circular_shifted_chain_code = get_circular_shifted_chain_code(chain_code);
cout << "循环首差链码:";
for (int i = 0; i < circular_shifted_chain_code.size(); i++) {
cout << circular_shifted_chain_code[i] << " ";
}
cout << endl;
return 0;
}
```
在运行代码之前,请先将名为“binary_image.png”的二值图像文件放在代码所在的目录中。运行后,程序将输出8链码和循环首差链码的结果。
