In this paper, we investigate the problem of channel bounding in wireless local area networks (WLANs). We propose a MAC protection mechanism to combat the hidden node problem on non-primary channels of a basic service set (BSS). Simulation results show that the proposed MAC protection mechanism is effective in combating hidden nodes and improving throughput of 80MHz stations. The proposed scheme has...
In this paper, a novel method for recognizing logos in natural images is presented. The difficulties lie in: (1) the logos in different images are highly variated in shape and location; (2) images will usually have several different kinds of logos; (3) the logo will be occluded by other objects, which traditional methods usually fail. Therefore, a learning-based logo recognition method is proposed...
