The goal is to simplify the neural-computing of biovision process modeled inthe Boundary Contour System of FACADE theory, and to extract subjective contour in.a new way. The procedure consists of DOG filtering, cooperative filtering,post-processing of cooperative cues and regrouping of endpoints, corresponding to theoriented edge filtering by simple cells, cooperative filtering by bipole cells and end-stopeffect formulated by hypercomplex cells in biovision system respectively. The last oneis an algorithm based on connection relation graph, which judges whether two keypoints should be connected according to their positions and orientations and thenconnect the key points that Should be connected to complete the subjective contour.

本文主要完成了以下工作：一是针对张量投票方法处理主观轮廓时出现的问题进行了改进，并依据矩阵的特征值摄动理论分析了该方法误差产生的原因以及迭代对其影响；二是用图像处理方法代替FACADE理论中复杂的细胞动力学方程，提出了一种基于视觉竞争合作机制的轮廓组织及缺口修复算法，该方法通过DOG滤波器组、合作滤波器组和张量投票等方法分别模拟视觉系统中的简单细胞有向滤波、双极细胞合作滤波和终端截断后端点重组等主观轮廓形成过程；三是提出了一种基于可连接关系图的算法解决轮廓组织及缺口修复问题，该方法在轮廓特征提取的基础上，根据关键点的位置和取向信息判断其可连接关系，进而连接具有可连接关系但没有实际连接的关键点，最终完成轮廓缺口的修复。

Based on Digital Elevation Model Data Space Analysis Technique, Yarlung Zangbo River drainage area is selected to be analyzed quantitatively to its landform and physiognomy by new obtained high precision SRTM DEM data. Typical physiognomy parameter of Yarlung Zangbo River drainage area is picked up economically, and a series of physiognomy analysis theme figures such as physiognomy highness, landform grade, slope direction and hypsography have been generated, which have been discussed and analyzed primarily. Profitable supplement has been made to new construction study of physiognomy boundary strap in the south of Tibetan Plateau.
