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

an image such that each description alone yields an acceptable

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 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)
