摘要
以生物视觉同时对比现象为基础,提出一种用于图像边缘检测的各向异性感受野模型。并对模型中边缘与算子中心长轴之间的角度关系对边缘检测效果的影响进行研究。实验表明,相对于各向同性感受野模型和一些传统的同方向各向异性边缘检测算子,所提出的感受野模型能够获得更加优越的边缘检测性能。
Based on the famous phenomenon of simultaneous contrast in biological vision, a new model of anisotropic receptive field used in edges detection is proposed. The relation between the edges detection performance and the angle of the edges and the orientation of the model＇ s long axes is then proved. The following experiments indicate that the proposed anisotropic receptive field can obtain more ideal filtering performance compared with the sotropic receptive field model and several kinds of traditional edges detection operator.
