数组变换图片

这次先上效果图：

/*
图像感兴趣区域设置处理

#include<opencv2\opencv.hpp>
#include<iostream>
using namespace cv;
using namespace std;
int main() {
	double t = (double)getTickCount();

	Mat img = imread("D://图片//1.jpeg");
	Mat log = imread("D://图片//5.jpg");
	Mat result = img.clone();

	if (img.empty() || log.empty()) {
		cout << "加载失败！" << endl;
		return -1;
	}

	Mat imgroi = img(Rect(img.cols - log.cols, 0, log.cols, log.rows));

	log.copyTo(imgroi);   //直接复制到对应的区域

	//addWeighted(imgroi, 0.6, log, 0.5, 0, imgroi);   //三者的大小必须相同

	Mat imgX(img.rows, img.cols, CV_32F);
	Mat imgY(img.rows, img.cols, CV_32F);

	for (int i = 0; i < img.rows; i++) {
		for (int j = 0; j < img.cols; j++) {
			imgX.at<float>(i, j) = j;                 //保持在同一列
			imgY.at<float>(i, j) = i + 23*sin(j);
			/*
			imgX.at<float>(i, j) = j;         //竖直变换
			imgY.at<float>(i, j) = img.rows - i - 1;
			*/
		}
	}
	remap(result, result, imgX, imgY, INTER_LINEAR);

	//imshow("show_imgroi", imgroi);
	imshow("show_img", img);
	//imshow("show_log", log);
	imshow("show_result", result);
	
	double Time = ((double)getTickCount() - t) / getTickFrequency();
	cout << "Time = " << Time << endl;

	waitKey(0);
	destroyAllWindows;

	return 0;
}
