Abstract

It has been shown, that high resolution images can be acquired using a
low resolution sensor with non-regular sampling. Therefore,
post-processing is necessary. In terms of video data, not only the
spatial neighborhood can be used to assist the reconstruction, but also
the temporal neighbor-hood. A popular and well performing algorithm for
this kind of problem is the three-dimensional frequency selective
extrapolation (3D-FSE) for which a motion adapted version is introduced
in this paper. This proposed extension solves the problem of changing
content within the area considered by the 3D-FSE, which is caused by
motion within the sequence. Because of this motion, it may happen that
regions are em-phasized during the reconstruction that are not present
in the original signal within the considered area. By that, false
content is introduced into the extrapolated sequence, which affects the
resulting image quality negatively. The novel extension, presented in
the following, incorporates motion data of the sequence in order to
adapt the algorithm accordingly, and compensates changing content,
resulting in gains of up to 1.75 dB compared to the existing 3D-FSE.
