Description
I run gentexdata on the same image twice, once on the original image and once on a copy of the image.
The first time i select 4, which is the highest value for extraction of tracking features, 3 the highest for initializing features and 10 for mindpi 80 for maxdpi. The second time i select 0 (lowest) for tracking features and 0 (lowest) for initializing features, mindpi 10 and maxdpi 80.
when i run dispfeatureset on the two fsets i get the following:
Extraction level for tracking features 4
Extraction level for initializing features 3
Min_dpi 10
Max_dpi 80
Size = (1000,563) Zoom = 1.000000

Why is the number for initializing features the same?
fset contains the features for continuous tracking and fset3 the features for the recognition in the first place, right?
