[OpenCV] What do the "left" and "right" values mean in the haar cascade xml files?
- by user117046
In OpenCV's haar cascade files, what are the "left" and "right" values, and how does this refer to the "threshold" value? Thanks!
Just for reference, here's the structure of the files:
<haarcascade_frontalface_alt type_id="opencv-haar-classifier">
<size>20 20</size>
<stages>
<_>
<!-- stage 0 -->
<trees>
<_>
<!-- tree 0 -->
<_>
<!-- root node -->
<feature>
<rects>
<_>3 7 14 4 -1.</_>
<_>3 9 14 2 2.</_></rects>
<tilted>0</tilted></feature>
<threshold>4.0141958743333817e-003</threshold>
<left_val>0.0337941907346249</left_val>
<right_val>0.8378106951713562</right_val></_></_>
