We introduce a new spectrum transform into the image fusion field and propose a novel fusion method based on discrete fractional random transform (DFRNT). In DFRNT domain, high amplitude spectrum (HAS) and low amplitude spectrum (LAS) components carry different information of original images. For different fusion goals, different fusion rules can be adopted in HAS and LAS components, respectively. The proposed method is applied to fuse real multi-spectral (MS) and panchromatic (Pan) images. The fused image is observed to preserve both spectral information of MS and spatial information of Pan. Spectrum distribution of DFRNT is random and uniform, which guarantees that good information is reserved. 相似文献

本文针对二维Mesh结构片上网络,在转弯模型的基础上提出一种新的路由算法——区域转弯算法,以获得更低的延迟时间和更高的吞吐率.该算法利用当前节点的X坐标,将整个Mesh网络划分为两个部分,目的节点X坐标小于当前节点X坐标的实行西优先算法,反之实行北最后算法.仿真结果表明,该算法相比于XY路由算法,平均延迟时间有所降低,当负载为40cycles/message时,延迟时间降低最大,为13.99%.吞吐率在负载为20cycles/message时最大提高13.56%. 相似文献
