Stereoscopic image interpolation using a spatially variant regularisation approach
Zhenyu Liu · International Journal of Electronics · 2014
This paper studies the problem of stereoscopic image interpolation, where a pair of images with mixed-resolution is given. Specifically, one image yields a low resolution, while the other one yields a higher resolution. The aim of the proposed approach is to reconstruct another pair of images with same high resolutions. To achieve this objective, the proposed approach imposes a regularisation on the reconstructed high-resolution image to perform image interpolation. Furthermore, the degree of regularisation is adaptively adjusted according to the local gradient of the reconstructed high-resolution image. Experiments are conducted to demonstrate that the proposed approach outperforms several conventional image interpolation approaches.
