Abstract
This paper explores several encoder-side techniques aimed at improving the compression performance of encoding for the draft JPEG XR standard. Though the syntax and decoding process are fixed by the standard, significant variation in encoder design and some variation in decoder design are possible. For a variety of selected quality metrics, the paper discusses techniques for achieving better compression performance according to each metric. As a basic reference encoder and decoder for the discussion and modifications, the publically available Microsoft HD Photo DPK (Device Porting Kit) 1.0, on which the draft JPEG XR standard was based, was used. The quality metrics considered include simple mathematical objective metrics (PSNR and L∞) as well as pseudo-perceptual metrics (single-scale and multi-scale MSSIM).
