70 results about "C-value" patented technology

C-value is the amount, in picograms, of DNA contained within a haploid nucleus (e.g. a gamete) or one half the amount in a diploid somatic cell of a eukaryotic organism. In some cases (notably among diploid organisms), the terms C-value and genome size are used interchangeably; however, in polyploids the C-value may represent two or more genomes contained within the same nucleus. Greilhuber et al. have suggested some new layers of terminology and associated abbreviations to clarify this issue, but these somewhat complex additions are yet to be used by other authors.

Color image compression via spectral decorrelation and elimination of spatial redundancy

ActiveUS6944333B2High spatial redundancyLess coloringTelephonic communicationCode conversionData setColor Cell Compression
A method of compressing a color image is provided. The color image comprises color data for a plurality of pixels. The method includes the step of obtaining red, green and blue pixel values of an object of interest in the image. A calculation is made of the complement of the red, green and blue values of the object of interest. Transformation coefficients are calculated which transform the complements of red, green and blue values of the object of interest into representations in a transformation color space. The transformation coefficients are applied to all the pixels in the image to thereby obtain a transformed data set representing the image having components along three mutually orthogonal axes (A, B and C herein) in a three-dimensional transformed color space. The transformed data set is scaled in accordance with the color quantization used in the system; e.g., the A, B and C values are between 0 and 255 for an 8 bit quantization. A compression algorithm, e.g., a loss less algorithm such as WINZip or LZW is applied to at least two components of the transformed data set to thereby produce output data representing a compression of the image.
