摘要：

Discusses the problem of how to evaluate various operators used for estimation of derivatives in images. Such operators are extremely commonly used, for instance to detect edges. The paper gives new insights in the interconnected concepts of edge detectors, line detectors, derivative operators, rotation invariance, and rotational symmetry. -after Authors
