Description

Hi!
I have found that in all new-style *.xml files at (i.e.):

...
<opencv_storage>
<cascade type_id="opencv-cascade-classifier"><stageType>BOOST</stageType>
<featureType>HAAR</featureType>
<height>25</height>
<width>15</width>
...

height and width values are reversed. So, detection works in wrong way. If i swap this values then all stuff becomes correct. (Btw, for frontal face detection all works fine because of square area :) )

Besides fixing it, we should look also if the creation of models is wrong or if the conversion of models was wrong in order to evade these problems in the future.

PR for 2.4 https://github.com/Itseez/opencv/pull/3662

my guess probably something went wrong when switching from old model structure to new model structure.
