Detailed Description

An interface to the C language library implementation of the.

Kanade-Lucas-Tomasi (KLT) feature point tracker by Birchfield, which is included.

The Birchfield library was last seen at http://vision.stanford.edu/~birch/klt/klt1.1.5.tar.gz

The KLT algorithm is described in:

Shi, Jianbo and Tomasi, Carlo, "Good Features to Track", IEEE Conf. on Computer Vision and Pattern Recognition, 1994.
