- Abstract
- A multiple description (MD) coding scheme encodes
an image such that each description alone yields an acceptable
reconstruction quality, and the descriptions together render
increasingly better approximations of the image. Traditionally,
each description contributes equally to the reconstruction quality
throughout the image. This is inefficient from a coding perspective
since all descriptions largely represent similar source
information. We suggest a novel region of interest (ROI) based
MD coding scheme with two descriptions and two ROIs, such that
each ROI is coded into a separate description. The impact this
scheme has on visual reconstruction... (More) - A multiple description (MD) coding scheme encodes

scheme has on visual reconstruction quality and coding efficiency
is investigated. We argue that ROI based MD coding is beneficial
at low bit rates since it (i) introduces little redundancy between
the descriptions with practically no loss in quality at the central
decoder, and (ii) still produces useful side descriptions. Extensions
to video coding are discussed in the concluding section. (Less)
