Abstract:Vertebrae tracking in videofluoroscopy is a challenging problem because of the low quality of image sequences, like poor image contrast, ambiguous geometry details, and vertebrae rotation. The aim of this article is to tackle this problem by proposing a method for rigid object tracking based on the fragmentation of the tracked object. The proposed method is based on the particle filter using the calculation of the similarity between the respective fragments of objects instead of the whole objects. T… Show more
