基于空间复杂度掩盖的边缘检测算法

An Edge-detection Algorithm Based on Spatial Activity Masking

通常边缘检测算法仅仅考虑到图像本身信息,而未考虑人眼对规则图像的感知能力比对非规则图像更强。结合人眼的视觉特性,本文提出了一种基于空间复杂度掩盖的边缘检测算法。给出了一种空间复杂度的测度以及双门限机制,利用图像空间复杂度来体现图像的规则程度,并根据图像的纹理信息矫正图像的梯度方向,确定边缘宽度,准确定位空间复杂度的计算区域。实验结果表明,本文提出的算法可以有效地检测规则图像的边缘,抑制复杂纹理区域的边缘。因此,该算法更符合人眼的视觉特性,有利于复杂情况中信息的提取。

Based on the characteristics of human vision, an edge-detection algorithm based on masking the image with the spatial activity is presented. Edge-detection algorithms usually deal with the image s original information without the characteristics of human eyes, more powerful perceiving ability on regular images than the other parts. In this paper, methods for measuring the spatial activity and a double-thresholds mechanism are proposed. The regular extent is represented using the spatial activity and the mas...
