摘要
利用lαβ域对颜色的控制力和图像位平面的嵌入策略特点,按照提出的组合位平面规则l、α、β分量图进行改变。在l中嵌入鲁棒参数,以RAID4方式在α和β中嵌入隐藏信息。应用混沌映射和遗传算法提高信息与载体一致性,并以骑士巡游路线在各位平面上进行遍历。实验表明,不可见性与鲁棒性平均提高8.94%和9.88%。
Based on controllability of lαβ domain to color and embedding strategy of image bit plane,l,α,β component images are changed according to proposed Combination Bit Plane（CBP） rule.Embed robustness parameter in l,hiding data in α and β by RAID4 and traverse all bit planes with Knight-tour route.Moreover,consistence of information and original image is improved with chaotic map and genetic algorithm.Experimental results show that imperceptibility and robustness are improved by 8.94% and 9.88% averagely.
