摘　　要：针对传统边缘检测算法的不足,提出一种以组织型P系统为框架的梯度边缘检测算法。采用一个两层膜结构,即表层膜与基本膜,使用转运规则实现各基本膜间的对象交换与共享。该算法逼近强度函数的梯度方向,基于梯度进行边缘的检测,并通过经典边缘检测算子的对比实验,实验结果表明所提出的边缘检测方法具有较好的有效性。Aiming at the shortcomings of traditional edge detection algorithms, this paper presents a gradient edge detection algorithm using tissue P system as the framework. The system adopts a two-level structure, i. el the outermost membrane and the elementary membrane. The communication rules are employed to realise the exchange and share of the objects among elementary membranes. This algorithm approaches the gradient direction of intensity function, and detects edges based on gradient. By contrast experiment using classic edge detection operator, the experimental results illustrate that the proposed edge detection method has good effectiveness.
