SPECTRUM-ADAPTIVE BAND-LIMITING TECHNIQUE FOR 3-D NONORTHOGONAL SAMPLING

This paper proposes a three-dimensional (3-D) band-limiting technique for a conversion of Simple Cubic Sampling into Body-Centered Cubic Sam pling. Based on spectral distribution of the original signal, the prop osed method adaptively varies the passband shape of a band-limiting fi lter in order to preserve informations of the original picture. By app lying this method to 3-D moving pictures, we can preserve resolution o n each axis without introducing heavy aliasing error and avoid degrada tion of picture quality such as ringing in still pictures or blurring in moving pictures. The examples given in this paper demonstrate these advantages.
