ABSTRACT Region of interest (ROI) coding has become a new challenge for low
bandwidth media channels. This paper presents an original method for low
bit rate compression using this concept. It is based on a new
progressive coding technique called LAR (Locally Adaptive Resolution)
combining a spatial nonuniform sampling and a variable block-size
spectral transform. Only little overhead is required for the ROI shape
description, and the data structure enabling the inner ROI enhancement
is totally correlated to this shape. This technique is also very fast,
allowing real-time and interactive multimedia applications
