How to apply a temporal filter to a stereoDepth node?

jarvis

According to the tutorial, a median filter can be applied by stereo.initialConfig.setMedianFilter(median), but the maximum disparity value exceeds the max value to apply a median filter. However the disparity has noise, and I want to try other filters. How to apply them?

Not really sure what this means. Any error you are getting?

The application should be the same as for the median filter. Just swap the filter for the desired one.

jakaskerl Great thanks, that helps. The error appears when activating the extended and the median filter at the same time of the stereo depth camera.

Hi jarvis
Using this example: https://docs.luxonis.com/projects/api/en/latest/samples/StereoDepth/depth_preview/
I modified the depth.setExtendedDisparity() to True. I am not facing any issues.
Make sure you are running the latest depthai version.

Can you confirm?

Thanks,
Jaka
