smoothing mouse movement

问题:

I'm developing a software to move the mouse based on certain coordinates which i get from a depth image from kinect. but I have 30 frames/second(images/second) and those coordinates changes with every frame so the mouse keeps moving. My question is,Is there a way to smooth the movement of the mouse ?

回答1:

Yes you can start tracking with some parameters that allows you to make move smoother.
Below is an example code:

        var parameters = new TransformSmoothParameters
        {
            Smoothing = 0.2f,
            Correction = 0.0f,
            Prediction = 0.0f,
            JitterRadius = 1.0f,
            MaxDeviationRadius = 0.5f
        };

        this._sensor.SkeletonStream.Enable(parameters);

You can change Smoothing, Correction, Prediction, JitterRadius, and MaxDeviationRadius to whatever numbers you want.

Since you wanted to know about "mapping depth coordinates to skeleton points", you can use the DepthImageFrame's MapToSkeletonPoint() which takes the X and Y values of the depth data and then create a SkeletonPoint. Example:

 SkeletonPoint point = depthFrame.MapToSkeletonPoint(x, y);

Hope this helps!
