随机修复场模型的改进

Improvement on the Stochastic Completion Field

摘要: 主观轮廓是一种重要的视觉心理现象，体现了人类视觉惊人的感知修复能力，而随机修复场模型则是针对主观轮廓提出的一个比较有影响力的计算模型。针对随机修复场模型存在的问题提出了一个改进方案。该方案建立了一个根据图像边缘的位置和取向构成的几何关系提取主观轮廓的综合性解决方法。实验结果验证了算法的有效性。

Abstract: Recognizing subjective contour is an important visual psychological phenomena, which demonstrating remarkable capability of human vision. Among the related works on subjective contour extraction, the stochastic completion fields model stands out. However, there are still some computation problems of this model which are still unsolved. This paper presents a perceptual completion method for subjective contour to overcome these problems. The algorithms suggested use edge evidences and local orientations to constrain possible geometrical groupings and completions and experimental results show its superiorities.
