             abstract = "This paper presents a novel methodology to perform consistent 
                         matching between visual features of a pair of images, particularly 
                         in the case of point-of-view changes between shots. Traditionally, 
                         such correspondences are determined by computing the similarity 
                         between descriptor vectors associated with each point which are 
                         obtained by invariant descriptors. Our methodology first obtains a 
                         coarse global registration among images, which constrains the 
                         correspondence space. Then, it analyzes the similarity among 
                         descriptors, thus reducing both the number and the severity of 
                         mismatches. The approach is sufficiently generic to be used with 
                         many feature descriptor methods. We present several experimental 
                         results that show significant increase both in accuracy and the 
                         number of successful matches.",
