Introduction

THIS PROJECT IS MOVED TO http://wiki.blender.org/index.php/BlenderDev/ReconstructionAndMotionTracking AND MANAGED BY Keir.

• http://mediawiki.blender.org/index.php/Competitive_Analysis/Matchmovers_and_Camera_Trackers

Two options to solve a match-move and a camera track:

• A motion tracking to animate bodies or faces, set a interested points to track and asign to controls of blender.
• An estimation of camera parameters and reconstructs a 3D scene. It useful to make postproduction and a model integration.

Project Goals

• Make a good motion tracking
• Interact with videos and cameras.
• Insert/delete keys points.
• Asign keys points to empties to animate anything.
• Moving things that can be garbage matted (poly mask). Or detect this point with some optical flow algorithm.
• More to define...

We have a first simple tracker. I paint over image editor the track points.

ToDo:
* The points will store in permanent array data with ipo anim.
* Make a hide/show points with sima on drawimage.c
* After we cvCalcOpticalFlowPyrLK we need make a call to cvGoodFeaturesToTrack 
to find new points, we must remove the duplicate points
* more...

• Look for best software to work
• Look for doc and papers

2007/01/21

• We go to use opencv and see the bazar tools
• Use image editor to make the tracking interface

Personal Notes

* Revisar Documentacion proyectiva 3d ...
* Find info about EGOMOTION
* don't forget to edit write.c/read.c to set the void* as NULL on fileload (to struct TrackData) Thanks Genscher
