| Abstract(in English) | We propose a new measure for appearance matching by qualitative trinary representation (QTR) which is based on equivalence relation or magnitude relation of neighboring pixel values. For each image, QTR assigns two trinary images based on the sign of difference between neighboring pixel values concerning vertical and horizontal direction, and determines the similarity by matching the trinary images. The representation has robustness against partial occlusion, or some intensity conversion. In this paper, we describe properties of QTR and compare them with those of conventional methods through several experimental results. Since QTR is computed only by the operations of comparison, addition and subtraction, the matching cost can be kept very low. Moreover, a hybrid matching with sufficiently high speed and accuracy is feasible by applying QTR to a quantitative matching at the pre-processing stage. |
