The LAR (Locally Adaptive Resolution) method is a multi-layers still image coding scheme, efficient from very low to high bit rates. The first stage is devoted to the representation and compression of the global information (low resolution image), and relies on an adaptive resolution in the image. This paper presents some improvements on the first layer through an original quad-tree like decomposition based on a predictive scheme, and the integration of a powerful interpolation post-processing. Comparative results with state of the art compression method are also presented and discussed.
