Resolution Enhancement of Images and Video

[an error occurred while processing this directive]

In many video imaging applications, it is of interest to enhance the resolution of the sensing device by resorting to software, rather than making expensive hardware modifications. This aim is realized in super-resolution processing, where an unaliased image (or sequence) is extracted from a sequence of lower resolution images. We have developed computationally efficient and statistically robust algorithms for performing this inversion. We have developed a comprehensive software package which implements our techniques and several other techniques.
