On the basis of active region model, a new region energy is proposed based on 2D entropy. In this new model, we describe region information using 2D entropy, which is robust to biggish noise regions . By listing non-parametric method .

• 本文提出了一种新型的主动区域模型(Active region model),构建基于二维熵的新型区域能量,并加入边缘信息,使模型在边缘和区域的共同作用下演变。
