Description

Hi there,
some time ago I added a bug report for the cv::remap function that seemed not to work with 16bit short arrays. It seems, that this is also the case for the cv::resize-function.

See this code:

cv::Mat_<short> img(120,160);
img.setTo(cv::Scalar(1));

cv::Mat reImg;
cv::resize(img,reImg,cv::Size(320,240),0,0,cv::INTER_CUBIC);

This code fails when using the OpenCV2.0-release as well as the actual svn trunk!

Regards
Matthias

Me again,
I just found out, that only signed short arrays aren't handled correctly. If you pass a unsigned short array to the resize function everything works out just fine. Hope you can fix this fast!

cv::Mat_<unsigned short> img(120,160);
img.setTo(cv::Scalar(1));

cv::Mat reImg;
cv::resize(img,reImg,cv::Size(320,240),0,0,cv::INTER_CUBIC);

This code works like charm...
