Local Energy Diffusion Field for snake algorithm

In this paper, a new snake external force is proposed as the gradient of the image local energy diffusion potential. The local energy is computed using a bank of orthogonal log Gabor filters. The proposed Local Energy Diffusion Field (LEDF) is computed by energy diffusion Partial Differential Equation (PDE). The results of the LEDF snake were compared with the GVF snake in terms of capture range, and convergence to concavities. Experimental results showed that the LEDF field provided a wide capture range and smooth field in the object concavities.
