The matter of Resolution Enhancement has become one of the
most important Electronic and Digital processing applications in
the last few decades. Super Resolution is one of the techniques
used for Resolution Enhancement. Super resolution techniques
are used to provide higher resolution of an image without
distorting an image. Super resolution can be done using two
ways: Single frame and Multi frame. For the former directly an
interpolation technique can be applied to get a high resolution
image from a low resolution image and for later multiple low
resolutions images can be combined to form a high resolution
image. Using this techniques resolution of any digital or
electronic system can be enhanced. This paper addresses the
matter of image super-resolution, which is the strategy by which
one or more low-resolution images are processed together to
create an image of high quality or set of images with a higher
spatial resolution. Multi-frame image super-resolution refers to
the particular case where multiple images of the spot are
available.
