主 题：Hybrid image Contrast sensitivity Frequency filtering Scale-space
摘 要：A hybrid image allows multiple image interpretations to be modulated by the viewing ***,it can be constructed by combining the low and high spatial frequencies of two different *** original hybrid image synthesis was limited to similar shapes of source images that were aligned in the edges,e.g.,faces with a different expression,to produce an effective double image *** our previous work,we proposed a noiseinserted method for synthesizing a hybrid image from dissimilar shape images or unaligned *** this work,we propose a novel method for adding an image to be seen from a middle viewing *** middlefrequency(MF)image is extracted by a special bandpass filter,which generates ringing while extracting only specified frequency *** this method,the middle frequency should be perceived as a meaningless pattern when viewed from a far distance and close up.A parameter tuning experiment was performed to determine the suitable cutoff frequencies for designing the filter for the MF *** found that ringings of a suitable size could be used to make the middle frequency less noticeable when seen from far away.
