SICE Annual Conference 2007
Preserved Fulltext
From this point of view, this paper treats the figure-ground separation problem in the random dot kinematogram. ...
The recognition process is described as the flag dynamics, which is given as the gradient system of the global potential functional. The performance is examined with computer simulations. ...
In other words, the figure-ground separation is a minimization process of the functional (4) in this system. ...
