Demos from ZIP file containing :
- Mode1low.AVI – 3.7 Mo : Experimental video data
- datamode1.txt – 51.2 ko : Results from KLT trackers
- out.avi – 51.4 Mo : Output video of the KLT algorithm
- lkdemoresonance2.cpp : KLT algorithm
- testmode1.m : matlab code to extract trackers signals
Using Ch/OpenCV
just launch the lkdemoresonance2.cpp then
Hot keys :
- ESC - quit the program
- r - auto-initialize tracking
- c - delete all the points
- n - switch the \"night\" mode on/off
- Left click (To add/remove a feature point click )
- Right click (run KLT)
