Extract exact eye region (Region doesn't fit eye exactly) #1

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago
Currently the eye region is recognized by a cascade of Haar-based
classifiers...

When detecting the eye region, the eye ofton does not lie completely in the
region's rectangle. Sometimes a corner is cut away.

Maby try some other haarcascade (for instance the ones from Modesto
Castrillon-Santanaones) to fix it:

e_mcs_lefteye.xml
and

e_mcs_righteye.xml

and

e_mcs_lefteye.xml
and
http://code.google.com/p/klucv2/source/browse/trunk/data/haarcascades/haarcascad
e_mcs_lefteye.xml

I expect the detected eye rectangle to exactly fit the eye at least when
looking at the camera in frontal view.

Fixed in r14 and improved in later revisions. The solution was to take two 
distinct
MCS-Haar cascades for left and right eye.
