Overview of external readers and the Altair Binary Format, the generic ASCII reader, running applications in batch mode, using Tcl/Tk commands, translators, and result math.
- Extensions
  Extensions are programs integrated with the application to enhance or extend the user experience.
- External Readers and Altair Binary Format
  Altair Binary Format (ABF) is the standard binary format read by the program. A library called abflib allows you to create files in ABF.
- Generic ASCII Reader
  A generic ASCII reader is now available which allows you to bring custom results directly into HyperView. The Altair ASCII format is useful for reading the results of any in-house or propriety codes which are saved in a generic format.
- Batch Mode
  Batch mode allows you perform a series of operations outside the program interface.
- External Resources
  External resources can be registered in preference files, session files, or Templex files. If an external resource is registered in a program session, it is automatically registered in the session file when the session is saved.
- Python API
  The Python API documentation for HyperMesh applications.
- Tcl/Tk Commands
  The application's scripting interface is a set of Tcl/Tk commands that follow a simple and consistent syntax.
  - Program with APIs for Beginners
    APIs can be used to perform various actions in an application. For example, the AddPage API can be used to add a page within the project.
  - Object Hierarchy
    Overview of object hierarchy for HyperView, HyperGraph, HyperMesh, MotionView, MediaView and TextView.

amfIMovie CalculateTrackingData

Calculates the tracking data, using the OpenCV tracking functionality, for the markers.

Syntax

movie_handle CalculateTrackingData speedup

Description

Invokes the OpenCV tracking functionality and runs tracking calculations for all the markers specified as needing recalculation.

Inputs

speedup

The speedup parameter is optional, and has the following acceptable values:

0 (Default Value): This will result in the value set by amfIMovie::SetSpeedupTracking being used. See section 9.17 for more information on the SetSpeedupTracking API.
1-10: The video resolution will be divided by this number before calculating. A value of 1 will result in no speedup, while a value of 2 will yield the greatest speedup benefit with the safest results. A value which is too high will result in inaccurate tracking results, and higher values yield only marginally better speed.

Example

movie_handle CalculateTrackingData 2

Error

Standard hwResult error codes:

1 = HW_Error
3 = HW_InvalidHandle
4 = HW_InvalidArgs
