ILMVGhost Interface

Data Types

This filter has no specific data types, but offers the following enumeration for use with its programming interface:

REFERENCE_FRAME

enum REFERENCE_FRAME 
{ 
   REF_USEBUFFER, 
   REF_USENEXTFRAME, 
   REF_USECOLOR, 
}; 
Enumeration Description
REF_USEBUFFER only the pBuffer member is used.
REF_USENEXTFRAME the next frame in the movie is taken as the reference frame.
REF_USECOLOR the lRGBColor parameter is used.

Properties

Type Name Description
VARIANT_BOOL Enabled Enables or disables the effect. If set to VARIANT_FALSE, the filter will pass the video samples intact.
VARIANT_BOOL FirstFrameIsReference Enables or disables setting the first frame in every play session as the reference frame. Possible values are:
• VARIANT_TRUE - the first frame in every play session will be set as the reference frame (Usually the first frame in a movie).
• VARIANT_FALSE - then the reference frame should be set manually after a number of frames. Setting this property after the stream starts will have no effect.
long Threshold Value used to control an object's detection level. A lower threshold provides stronger object detection. Range : 1 to 100.

Methods

HRESULT SetReferenceFrame (byte *pBuffer, long lRGBColor, REFERENCE_FRAME opt)
