The
aim of this lecture is to describe the basis
of image and video coding and compression, with a
special emphasis on the latest developments. We will
see how to encode and compress this particular type
of data using lossy algorithms that take
advantage of the limitations of the human visual
system.
We
will focus on scalable image and video coding,
which is a cutting-edge area of research, an area
were few fully recognized standards have emerged
yet.
Sometimes, specialized
developers
need to design systems which require an image or
video (de)coder. Understanding the internals of some
coding systems may help them in to select the
most appropriate approach (streaming systems,
pattern recognition systems, etc.) and
algorithm (JPEG, JPEG2000, MPEG-2, MPEG-4, WMV,
etc.).
We
will present techniques used in well-known
algorithms and the audience will have the
opportunity to learn the fundamentals through
practical examples.
