setLearningTime() in RunningBackground.cpp

[stephanschulz]

I was hoping someone could shine some light on setLearningTime()

• i taking an initial background reference

• the threshold image is all black (that's good)

• then people enter the room and cause white blobs in the threshold image (that's good)

• if they stay there too long and walk out they leave white white blobs behind (makes sense because they became part of the background and now create a new disturbance)

• BUT this new white blob takes much longer to disappear. longer than it took to learn it in the first place.

• if a person was present for 15 min and became part of the background, it should also only take a maximum of 15 min for the left-behind white blob to disappear. right?

• In an attempt to temporally disable learning i set the learning time to 5000x30. But still it learns in less than 5000x30 = 150,000 seconds. (but un-learning take longer. not sure how long)
