# Detection settings for Behavior recognition

Prerequisites

▪You have the Rat/Mouse Behavior Recognition Module.

▪In the Experiment Settings, under Tracked Features, you have selected Center-point, Nose-point and tail-base tracking. Under Analysis Options, you have selected Behavior recognition.

▪See also Behavior Recognition: Requirements

Procedure

1.Put the animal in the arena or play the video. Optimize the camera setup, and lighting conditions. Try to reduce reflections on the walls of the arena as much as possible.

2.Select the image source and sample rate. In the Detection Settings pane, under Video, select a value of sample rate between 25 and 30 samples/second.

See Video file, image quality and sample rate

3.Use the Automated Setup as described in Detection settings: Automated setup.

4.When detection is good, open the Behavior Recognition section in the Detection Settings pane and follow Advanced detection settings: Behavior recognition.

Notes

▪If detection with the Automated Setup is not good, in the Detection Settings pane, click Detection and then Advanced. Under Method, select one of the following:

▪Rodents / Default. This is selected automatically when you use Behavior recognition, and should work in most cases.

▪Rodents / For occlusions. Choose this method only when Default does not give good results. This option is optimal when there are objects in the arena (for example a novel object) which create occlusions and make detection of the whole subject’s body difficult.

▪The quality and amount of light is very important when using Behavior recognition. See Subject exposure
