Abstract(in English) | A change of illumination makes it difficult to recognize objects in the real world. Though many methods have tackled this problem, most of them have a weakness for geometrical transformations. In this paper, we treat the case of translation by using Higher-order Local AutoCorrelation (HLAC) features which is invariant under translation. First, we prove the set of HLAC feature vectors of an object with a lambertian surface forms a 3D manifold and is constrained in a linear subspace. Second, we consider such a property and propose a method which is robust to the change of illumination and position by applying a subspace method to HLAC feature vectors. |
