Multi-Directional Image Projections with Fixed Resolution for Object Matching
Acta Polytechnica Hungarica · 2014
The matching of the visual representations of two objects is a very important task in most computer vision applications.In special cases, when all objects look alike and only small differences occur, the difficulty of the task increases.In this paper, a novel method for matching low-quality images of rear-viewed vehicles is proposed, using multi-directional image projection functions.For GPU-accelerated implementations, a data-parallel algorithm is introduced.It is concluded, that the use of multiple directions with a small fixed resolution number is the most efficient, and more precise than similar techniques with smaller projection dimensions.
