Subject: Fix resize bug
X-Git-Tag: submit/tizen/20220701.002357~1^2~9
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=52fe22d4125eb4d776f43cd17acb52e01d9d59c1;p=platform%2Fcore%2Fmultimedia%2Fdfs-opencv.git

Fix resize bug

When resized images are back to their original sizes,
cv::Size() should be used, not an integer scale value
to handle the case of odd number size.
