Abstract:
In this paper, we propose TextTrail, a robust new
algorithm dedicated to text tracking in uncontrolled
environments (strong motion of camera and objects, partial
occlusions, blur, etc.). It is based on a particle filter
framework whose correction step has been improved. First,
we compare some likelihood functions and introduce a new
one that integrates tangent distance. We show that the
likelihood function has a strong influence on the text
tracking performances. Secondly, we compare our tracker
with another and finally present an example of application.
TextTrail has been tested on real video sequences and has
proven its efficiency. In particular, it can track texts in
complex situations starting from only one detection step
without needing another one to reinitialize the tracking
model.
