hi
thanks greg for ur help we have done some testing using open cv in native python
can u sugguest some filter examples to remove granual noise
some problems we have noted:
1)problems in detecting very dark colour cars
2)unable to maintain a threshold due change in sun direction
Erode also Blurring can
Erode also Blurring can remove granular noise. As I mentioned before PyramidDown is under utilized. It also can reduce noise - the reason being is your shrinking your domain problem data.
Not only does it reduce noise, but its also quicker.
