Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we propose a two dimensional (2D) nonseparable directional filter bank (DFB) based on the cosine modulated filter bank (CMFB). Although 2D CMFBs have been proposed, conventionally, the frequency shift method proposed in this paper is different from the conventional method. The proposed DFB has frequency partitions which can not be realized via the conventional ones. The cosine modulated system is well-known for its low complexity and low design cost. Therefore, we propose the DFB which is implemented with low complexity and low design cost. Through the simulation, we show that the proposed DFB have efficient frequency responses.
