NVeiler Video Filter

Plug-in for VirtualDub that hides faces and objects

The NVeiler Video Filter is a plug-in for VirtualDub video processing software. The plug-in automatically detects faces in a frame and hides them by using pixelation effect. Also it is capable to track the moving faces in subsequent frames and hide them, as well as detect new faces without user intervention.

Users can choose to hide selected faces or parts of the faces, as well as use the plug-in for hiding other objects.
