我正在尝试通过Opencv库将以下MATLAB代码转换为c ++代码
Matlab代码：
scale_x = 0.99951;
scale_y = 0.99951;
RsrcImg= imref2d(size(im1));
T=[scale_x 0 0;0 scale_y 0;0 0 1];
tformEstimate = affine2d(T);
destImg =imwarp(im1,tformEstimate,'Interp','cubic','OutputView',RsrcImg);
C ++代码：
double scale_x = 0.99951;
double scale_y = 0.99951;
Mat tformEstimate=Mat::zeros(2,3,CV_64FC1);
tformEstimate.at<double>(0,0)=scale_x;
tformEstimate.at<double>(1,1)=scale_y;
warpAffine(im1,destImg,tformEstimate,im1.size(),INTER_CUBIC);
但我的PSNR值完全不同！有没有办法让两个代码都能使用相同的结果？
INPUT：
im1=[19656,20452,21048,21020,20564;
20740,21332,21964,20932,20220;
21688,21832,20236,21520,21948;
19780,20572,21056,20748,20088;
20560,21188,20608,22136,20736]
Matlab输出：
[19656.4613056001,20452.8984647534,21048.6416903208,21019.5009522438,0;

我见过 MATLAB vs C++ vs OpenCV - imresize 没有成功。
感谢您的帮助。
