DeNoise Filter

The DeNoise filter reduces noise in the frames by averaging a number of frames.

Using the DeNoise Filter

The DeNoise filter is loaded by an application using the following code:

[C#]
FrameFilter DeNoiseFilter;
DeNoiseFilter = ICImagingControl1.FrameFilterCreate("DeNoise", "");
if( DeNoiseFilter == null )
    MessageBox.Show("Failed to create DeNoiseFilter");
else
    ICImagingControl1.DeviceFrameFilters.Add(DeNoiseFilter);

Parameters

The only parameter of the DeNoise filter is the DeNoise Level:

DeNoise Level

The parameter DeNoise Level determines the number of frames to be averaged.

Note: The actual number of frames that are averaged is 2^n, so when setting DeNoise Level to 2, 4 frames are averaged.

This parameter can only be set while the live video stream is stopped.

Property Dialog

The number of frames to be averaged can be adjusted in the filter's property dialog:

Programmatically Access the Parameter

The following source code can be used, if the parameter should be set by an application:

[C#]
// Retrieve the current denoise level.
int level = DeNoiseFilter.GetIntParameter("DeNoise Level");
// Set a new denoise level.
level = 3;
if( !ICImagingControl1.LiveVideoRunning )
{
    // A new denoise level can only be set, while the live video is stopped.
    DeNoiseFilter.SetIntParameter("DeNoise Level2", level);
}
