Mosaicing
with Super Resolution
Assaf Zomet and Shmuel Peleg
Overview:
Given a video sequence scanning a static scene,
a panoramic image can be constructed whose field of view is the entire
scene. Since each region in the panorama is covered by many overlapping
image segments, its resolution can be enhanced. Since the alignment used
for mosaicing is usually not accurate enough at every overlapping pixel
for super-resolution, an additional alignment stage is performed after
the mosaicing stage.
1. A panorama is constructed.
2. for each strip in the panorama:
a. The location of the
strip in different frames is computed.
b. These strips are
aligned to the strip in the panorama.
c. A super resolution
algorithm (Such as Peleg
and Irani's) is applied on the aligned strips.
