论文摘要
本文涉及四元素强函数的局部特征的应用。该特征信息可以通过二聚型强度函数的极性形式（例如局部衰减和局部相位向量）提供。通过使用局部特征的广义Cauchy-Riemann方程，新开发了四种各种边缘检测器。实验结果表明，基于振幅的边缘检测器执行测试图像的包膜，而基于阶段的边缘检测器给出了测试图像的细节。我们提出的算法大大优于现有方案。
This paper is concerned with the applications of local features of the quaternion Hardy function. The feature information can be provided by the polar form of the quaternion Hardy function, such as the local attenuation and local phase vector. By using the generalized Cauchy-Riemann equations of local features, four various kinds of edge detectors are newly developed. The experiment results show that the amplitude-based edge detectors perform the envelope of test images while the phase-based edge detectors give the detail of the test images. Our proposed algorithms greatly outperform existing schemes.
