Application:track-video-features

Description:

The program track-video-features demonstrates live detection and tracking of features in a video stream. 

To invoke it, just type from the console:

$ track-video-features

and a GUI dialog will ask you to pick the video source (among video files, rawlogs, live firewire or USB cameras, a Kinect sensor, etc.). Alternatively, use:

$ track-video-features  <DATASET.rawlog>
$ track-video-features  <video_file.{avi/mpg/mp4/flv}>

to directly run it with a robotic dataset or a video file.

 

Source code:

 
The program is located at <MRPT>/apps/track-video-features/: http://browse-code.mrpt.org/stable/apps/track-video-features/track-video-feats_main.cpp
 
See this tutorial on the related data structures and classes.
 
 

Demo videos:

 

1. A short sequence in a typical office scenario: Test with a sample video sequence published by Andrew Davison among his MonoSLAM works.

 

2. An unmodified music video: This kind of videos are really challenging for computer-vision methods for the quick sequence changes, and for blurred and unfocused shots. Notice how features are hardly detected in those blurred images; the reason is that at present (sept-2011) only the first image pyramid is searched for FAST features in the program.
