Abstract

Complexity reduction in video coding and data size compression in stereoscopic video has been achieved with the use of mixed resolution formats. The high resolution frames within mixed resolution formats may also be used to enhance the low resolution frames. This paper presents a super-resolution technique for usage within a multiview video plus depth setup with mixed resolution. Available depth information is used to project high resolution views onto the view points of low resolution images. A transform domain technique is introduced to up-sample the low resolution image and to aggregate high frequency content from the projected view. The DCT is the adopted transform and results demonstrate objective quality gains for various sequences.
