摘　　要：提出了一个通过保留全部频带信息来保留色彩细节的多义图像合成系统。系统依据两个用户给定的视距或视角将不同含义的两个目标图像合成一幅多义图像。首先,通过视距和图像高度的函数来选择小波分解级,从而对目标图像进行小波分解;其次,根据可选的融合规则和权值变量融合并重构出在两个视角下的多义图像;最后,采取均值降噪的方法滤除结果图像噪波。实验证明,该系统能高效合成视觉效果醒目的图像并充分保留原目标图像的色彩和细节特征,有利于满足商用需求。A multi-meanings image synthesis system with reserved color detail was proposed.The multi-meanings image was produced by two target images with different interpretations and two viewing distances or viewing angles presented by user.Firstly,the target images were decomposed by wavelet transform with the scale which was a function of viewing distance and image height.Secondly,the multi-meanings image viewed in two angles was reconstructed by elective fusion algorithms and variable power.Finally,the result images were averaged for denoising.Experimental results show that the system is efficient and commercially suitable to produce multi-meanings image with compelling visible effect and containing sufficient color and details of original images.
