Abstract:
An effective shape signature, namely multi-level included angle functions(MIAFs), is proposed to describe the hierarchy information ranging from global information to local variations of shape. Invariance to rotation, translation and scaling are the intrinsic properties of the MIAFs. For each contour point, the multi-level included angles are obtained based on the paired line segments derived from unequal-arc-length partitions of contour. And a Fourier descriptor derived from multi-level included angle functions(MIAFD)is presented for efficient shape retrieval. The proposed descriptor is evaluated with the standard performance evaluation method on three shape image databases, the MPEG-7 database, the Kimia-99 database and the Swedish leaf database. The experimental results of shape retrieval indicate that the MIAFD outperforms the existing Fourier descriptors, and has low computational complexity. And the comparison of the MIAFD with other shape description methods also shows that the proposed descriptor has the highest precision at the same recall value, which verifies its effectiveness.
