IWR1443: Gesture Swipe recognition: Gesture_findNumDetections function

Varsha Vanga

Part Number: IWR1443

Hi,

I am working on IWR1443 gesture swipe recognition. I want to understand Gesture_findNumDetections function.

There is one input argument to this function detThresh its value is 8000. 

while Computing statistics for positive dopplers and  negative dopplers there is a line  rangeAvgPos+=(wt+4000)*i 

I want to understand why the value is 4000.

Is there any relation between detThresh  and this 4000 value?

Regards,

Varsha

    Hello,

    This is an empirically determined weighting factor and threshold. If you adjust one it may have an affect on the other. The lab has only been tested for the default values. Modifying the hand crafted classifier for your use case may require redetermining appropriate weighting and thresholds based off of data collection and testing.
