We also use estimators of circular dispersion to introduce edge detectors for angular signals.  ...  Particular emphasis is given to the circular median filter, for which some interesting properties are derived.  ...  An edge detector has good performance if is close to unity (and, therefore, close to zero) and tends to zero.  ...

In this paper, we describe a generic methodology for evaluating the labeling performance of feature detectors.  ...  We describe a method for generating a test set and apply the methodology to the performance assessment of three well-known corner detectors: the Kitchen-Rosenfeld, Paler et al., and Harris-Stephens corner  ...  Paler, Föglein, Illingworth, Kittler Detector [8] The Paler detector is based on the observation that median filtering does not greatly distort edges but does affect corners.  ...

The edge detection was applied by using sobel edge detector. Morphological algorithm, dilation, and erosion, opening, closing, hole filling and filtering algorithm were used [1] .  ...  The Canny operator was designed to be an optimal edge detector.  ...

The new feature detectors are based on the minimization of this local image region, and the noise reduction method uses this region as the smoothing neighbourhood.  ...  This paper describes a new approach to low level image processing; in particular, edge and corner detection and structure preserving noise reduction.  ...  This is a common approach, and indeed, only second order derivative detectors (including Noble's edge detector, but not including second order zero-crossing detectors) will give a response to the roof  ...
