Efficient Delivery of Very High Dynamic Range Compressed Imagery by Dynamic-Range-of-Interest
JPEG 2000 allows scenes to be encoded in a highly scalable and accessible manner, so that only the content that is relevant to a region or resolution of interest need be transmitted and decoded. This paper extends this property to allow efficient access into compressed images that have a very high dynamic range, based on a dynamic-range-of-interest. Optimized re-prioritization of the encoded content is used to stream imagery based on a potentially dynamic set of viewing conditions that implicitly identify the visual significance of content. We propose and validate a framework for doing this, based on a single compressed representation, a sparse set of display-independent luminance statistics and a novel algorithm for inferring the display-dependent significance of code-block distortions.
