Directional MAP to Adaptive Edge Detection by using Variograms

In this study, we suggest a new approach to the detection of edge orientation in order to guide a choice of the appropriate directional filter. This approach aims at analysing variograms properties such as the directionality, the renewal period of texture pattern and size of objet. The use of variograms enable to define directional MAP and to determine the edge orientation of the object in order to guide automatically and locally which optimal directional filter is used on area analysed.
