Public bug reported:

Sometimes I get these errors:

org.opencv.core.CvException: CvException [org.opencv.core.CvException:
cv::Exception: OpenCV(3.4.2) C:\build\3_4_winpack-bindings-
win64-vc14-static\opencv\modules\imgproc\src\templmatch.cpp:1107: error:
(-215:Assertion failed) _img.size().height <= _templ.size().height &&
_img.size().width <= _templ.size().width in function 'cv::matchTemplate'

Am I right in assuming they are to do with the region being too small or
not fitting the image/pattern I am searching for when it is found? I
think I am able to work around by extending/recapturing the region after
which these errors stop. But I am not 100% certain.
