    "abstract": "The author's previous paper “High Quality, Wide Dynamic Range, Compression System”, which was presented at SMPTE Pasadena in Oct 2004, described a highly layered precision lossy coding system. That paper introduced the concept that “visually lossless” lossy coding could be achieved by ensuring that the amplitude of quantization coding errors is always less than the inherent original image noise floor. In general, the original image noise floor is a function of brightness and color, and is sometimes a function of regions within a frame. This noise floor will also usually vary between shots and scenes.",
