Abstract:

To classify the features into the rigid and non-rigid ones, a low dimension matrix constraint method for non-rigid feature classification is proposed. All the non-rigid features are put into a matrix and an error function is introduced based on the fact that the matrix which consists of rigid features spans a 3D subspace. The feature which has a max error is regarded as the non-rigid one and moved from the matrix one by one. Experimental results with both simulated and real data show that the method can efficiently classify the features into two sets.

Key words: low dimension matrix, feature classified, non-rigid
