In this paper, we present a method of creating domain-based multiple descriptions of images and video. These descriptions are created by partitioning the transform domain of the signal into sets whose points are maximally separated from each other. This property enables simple error concealment methods to produce good estimates of lost signal samples. We present the approach in the context of Internet transmission of subband/wavelet-coded images and scalable motion compensated three-dimensional (3D) subband/wavelet-coded video, but applications are not limited to these scenarios. The results indicate that the proposed methods offer improvements over similar competing methods by up to 1 dB for images, and several decibels for video. Visual quality is also improved.
