Paper Abstract

Compared with unimodal wavelet packet subbands, multimodal subbands have strong texture discriminatory power. The existence of mulitimodal subbands in dual-tree complex wavelet packet transform is proved. Similar to the multimodal subbands in real wavelet packet transform, there are shift-modal subbands in complex transform to capture the periodicities running through the texture images. Furthermore, the stability of multimodal subbands in real transform is investigated through a classification experiment. It is concluded that, to the textures with small and very regular periodicities, stable multimodal subbands can be obtained.
