基于区域一致性测试的多尺度边缘检测方法
Multiscale Edge Detection Based on Region Homogeneity Measure

摘要: 在多尺度边缘检测方法中,滤波器的滤波尺度的选取非常重要,该文提出了区域一 致性测度的概念以度量当前像素点所处的区域是平滑区还是边缘区,并以此测度来自适应调 整滤波尺度.实验结果和分析表明,这种方法可以得到令人满意的结果,同时具有较好的抗噪 能力.Abstract: The most important thing in multiscale edge detection is the filter scale. Region homogeneity measure is defined to distinguish homogenous region from edge region. The cubic B spine wavelet whose scale is adjusted by the region homogeneity measure is used to detect edge. The experiment results and comparisons show that this method is effective and feasible.
