Boundary Extraction Using Poincare Map Method

Ruchita V. Indulkar, Sanjay D. Jondhale

Now a day’s active contours or snakes are used in many image processing applications, especially for locating the object boundaries and edge detection. But the problems of these models are initialization and poor convergence to deep concavities of the boundary and particularly equilibrium issues in the vector field. In the proposed method first the ISAF field is generated which is composed of swirling and attracting component (DETF & DEPF respectively). Then with the help of dynamical system limits cycles are set / located by Newton- Raphson algorithm in the Poincare section. And integral equations are used to connect these boundaries.
