motion blur appears near moving object in depth image when using filters

Camera : D435i
for example, inside the red box is a person moving from right to left, and the blur? appears

it only appears when using temporal, threshold or spatial filters

Hi @ysj2009 A blur like this would be likely to appear if the Temporal filter has been applied and a low value is set for the filter's 'Filter Smooth Alpha' parameter. A low value for this parameter causes the depth image to update less frequently and so leave a trail behind when capturing motion. You could test whether the Temporal filter is responsible by commenting out its .process line so that the filter is not applied.
