做暧暧视频网站日本seo是什么姓氏

1、说明

目标数据集合中有很多长条状图片，如果直接Resize 会严重拉伸，因此采用把长条图像裁剪成2段，然后将裁剪后的2段图片拼接在一起。

2、代码

2.1 C++ 代码 （部署，模型推理时C++ ）

#include <opencv2/core/core.hpp>  
using namespace std;
using namespace cv;
int main()
{cv::Mat img = cv::imread("_1.jpg", 1);cv::Mat dst;int src_h = img.rows;  int	src_w = img.cols;std::cout << "src_h " << img.rows << std::endl;std::cout << "src_w " << img.cols << std::endl;if (src_h > src_w && src_h > 600){int dst_h = int(src_h / 2) + 16;int dst_w = src_w * 2;cv::Mat blank(dst_h, dst_w, CV_8UC3, cv::Scalar(0, 0, 0));cv::Mat blank_1 = blank(cv::Rect(0, 0, src_w, dst_h));cv::Mat blank_2 = blank(cv::Rect(src_w - 1, 0, src_w, dst_h - 16));blank_1 += img(cv::Rect(0, 0, src_w, dst_h));blank_2 += img(cv::Rect(0, dst_h - 16 - 1, src_w, dst_h - 16));dst = blank.clone();}else if (src_w > 600 && src_h > 100){int dst_h = src_h * 2;                    // 566*2      = 1332int dst_w = int(src_w / 2) + 16;              // 1658/2 +16 = 845cv::Mat blank(dst_h, dst_w, CV_8UC3, cv::Scalar(0, 0, 0));cv::Mat blank_1 = blank(cv::Rect(0, 0, dst_w, src_h));cv::Mat blank_2 = blank(cv::Rect(0, src_h - 1, dst_w - 16, src_h));blank_1 += img(cv::Rect(0, 0, dst_w, src_h));blank_2 += img(cv::Rect(dst_w - 16 - 1, 0, dst_w - 16, src_h));dst = blank.clone();}std::cout << "dst_h " << img.rows << std::endl;std::cout << "dst_w " << img.cols << std::endl;cv::imshow("src", img);cv::imshow("dst", dst);cv::waitKey(0);
}
