<h5 dir="auto">Detailed description</h5>
<p dir="auto">cv::dnn::blobFromImage should support aspect-ratio resizing.<br>
It currently warps the image by stretching it if you don't crop.<br>
Making use of cv::copyMakeBorder is a workaround, but IMHO it could be part of the integrated preprocessing. This is especially important if your data has to keep aspect ratio inside the NN.</p>
