Junctions Analysis on the Projected Image of 3D Objects
- Detecting Y-and arrow-Junctions from Local Image Derivatives -
Abstract:Analyzing projected images is important for interpreting 3D objects. In particular, it is necessary to analyze such junctions as the Y- and arrow-junctions which are composed of multiple edges. This paper proposes a one-shot algorithm for detecting the Y- and arrow-junctions of projected images. This algorithm includes a stage to detect orientations of triple edges and another stage to classify junctions by using information on local image derivatives. Experimental results obtained by using our algorithm show that Y- and arrow-junctions can now be detected easily.
