Abstract: A method and system for accurate and precise representation of color for still and moving images, particularly sequences of digitized color images. Spectral and/or extended dynamic range information is retained as images are captured, processed, and presented during color adjustment. Using this extra spectral information, various methodologies for further presenting or processing the color within these images can be optimized. Presentation-device independence is achieved not by attempting to discover a device-independent intermediate representation, but rather by deferring the binding and mapping of color representation onto a presentation device until its actual use.

Abstract: Systems, methods, and computer programs for high quality wide-range multi-layer image compression coding, including consistent ubiquitous use of floating point values in essentially all computations; an adjustable floating-point deadband; use of an optimal hand-split filter; use of entire SNR layers at lower resolution levels; targeting of specific SNR layers to specific quality improvements; concentration of coding bits in regions of interest in targeted band-split and SNR layers; use of statically-assigned targets for high-pass and/or for SNR layers; improved SNR by using a lower quantization value for regions of an image showing a higher compression coding error; application of non-linear functions of color when computing difference values when creating an SNR layer; use of liner overall quantization at lower resolution levels with regional quantization scaling; removal of source image noise before motion-compensated compression or film steadying; use of one or more full-range low bands; use of alternate quantization control images for SNR bands and other high resolution enhancing bands; application of lossless variable-length coding using adaptive regions; use of a folder and file structure for layers of bits; and a method of inserting new intra frames by counting the number of bits needed for a motion compensated frame.

Abstract: Systems, methods, and processor executable code for high quality wide-range multi-layer image compression of a sequence of video images. A non-transient electronic storage media stores the processor executable code configured and is capable of causing one or more processors to compress a sequence of digitized video images. The method includes generating a hierarchy of processed images from a digitized video image, determining a plurality of regions within each processed image, each region being selected based on lossless coding efficiency; and applying a lossless variable-length coding independently to each such region.
