Super-resolution mosaicing from MPEG compressed video

In this paper, we describe a method for the construction of super-resolution (SR) mosaics. The low-resolution (LR) input sequence of the SR algorithm consists of DC images of I-frames (DCI-frames) extracted from MPEG compressed streams. For the registration of the LR sequence, the motion information from P-frames is used. The novelty of this approach is the determination of the optical transfer function (OTF) of the blur for the image restoration in the SR algorithm. First results are promising.
