Abstract

To solve the problem of vessel bifurcation and overlap

an adaptive tracking algorithm based on the constraint of directional information measure is proposed.In the heuristics tracking procedure

an edge measure function is defined to detect vessel edge.Simultaneously

some strategies are introduced to improve the detective precision

such as step adjustment

direction inertia and quadrangle modification.Experimental results show that the proposed algorithm can correctly track the vessel when bifurcate and overlap occurs.
