Define Documentation

#define IVIDANALYTICS_EOK   XDM_EOK

Success.

#define IVIDANALYTICS_EFAIL   XDM_EFAIL

General failure.

#define IVIDANALYTICS_EUNSUPPORTED   XDM_EUNSUPPORTED

Request is unsupported.

#define IVIDANALYTICS_SETRULE   XDM_CLASSCMDBASE

Set a new rule.

#define IVIDANALYTICS_CLEARRULE   XDM_CLASSCMDBASE + 1

Clear a rule.

#define IVIDANALYTICS_MAXTARGETS   128

Maximum targets that can be detected per process() call.

Todo:

This could be 64 if needed. Need to understand the size of structs that use this and whether they're "too big".

#define IVIDANALYTICS_MAXEVENTS   128

Maximum number of events that can be detected per process() call.

Todo:

Need to understand the size of structs that use this and whether they're "too big".

Typedef Documentation

typedef struct IVIDANALYTICS_Obj* IVIDANALYTICS_Handle

Opaque handle to an IVIDANALYTICS objects.

typedef IALG_Cmd IVIDANALYTICS_Cmd

Defines the control commands for the IVIDANALYTICS module.

Remarks:

This ID can be extended in IMOD interface for additional controls.

See also:

XDM_CmdId

IVIDANALYTICS_Fxns::control()

Enumeration Type Documentation

enum IVIDANALYTICS_AnalysisMask

Access modes used to declare how the algorithm accessed buffers.

Remarks:

The IVIDANALYTICS interface reserves bits 0-15. Bits 16-31 are available to the user.

See also:

IVIDANALYTICS_Mask::enableMask

Enumerator:

IVIDANALYTICS_MOTIONDETECT	Motion detection, bit 0
IVIDANALYTICS_OBJECTTRACKING	Object tracking, bit 1
IVIDANALYTICS_USERBASE	User supplied analysis begins at bit 16.

enum IVIDANALYTICS_ObjectType

Types of objects.

Remarks:

The IVIDANALYTICS interface reserves types 0-255. User-defined objects can be defined from 256 and larger.

Enumerator:

IVIDANALYTICS_OBJECTTYPE_VEHICLE	Object is a vehicle
IVIDANALYTICS_OBJECTTYPE_HUMAN	Object is a human
IVIDANALYTICS_OBJECTTYPE_USERBASE	User supplied objects begins at 256.

enum IVIDANALYTICS_ActionType

Types of objects.

Remarks:

The IVIDANALYTICS interface reserves types 0-255. User-defined actions can be defined from 256 and larger.

Enumerator:

IVIDANALYTICS_ACTIONTYPE_LOITER	Object is loitering
IVIDANALYTICS_ACTIONTYPE_ENTER	Object enters
IVIDANALYTICS_ACTIONTYPE_EXIT	Object exits
IVIDANALYTICS_ACTIONTYPE_APPEAR	Object appears
IVIDANALYTICS_ACTIONTYPE_DISAPPEAR	Object appears
IVIDANALYTICS_ACTIONTYPE_CROSSL2R	Object crosses left to right
IVIDANALYTICS_ACTIONTYPE_CROSSR2L	Object crosses right to left
IVIDANALYTICS_ACTIONTYPE_CROSSU2D	Object crosses up to down
IVIDANALYTICS_ACTIONTYPE_CROSSD2U	Object crosses down to up
IVIDANALYTICS_ACTIONTYPE_USERBASE	User supplied objects begins at 256.

enum IVIDANALYTICS_ViewState

View state of the analytics engine.

Remarks:

This enumeration data type should not be used for storage, but rather only for its constant values.

Todo:

Need to further review and define. Probably need hooks for user-defined states, in addition to some pre-defined ones.

See also:

IVIDANALYTICS_OutArgs::viewState

IVIDANALYTICS_Status::viewState

Enumerator:

IVIDANALYTICS_VIEWSTATE_BAD
IVIDANALYTICS_VIEWSTATE_GOOD
