  • Patent number: 11212539
    Abstract: Systems and methods for efficient lossless compression of captured raw image information are presented. A method can comprise: receiving raw image data from an image capture device, segregating the pixel data into a base layer portion and an enhanced layer portion, reconfiguring the base layer portion expressed in the first color space values from a raw capture format into a pseudo second color space compression mechanism compatible format, and compressing the reconfigured base layer portion of first color space values. The raw image data can include pixel data are expressed in first color space values. The segregation can be based upon various factors, including a compression benefits analysis of a boundary location between the base layer portion and enhanced layer portion. The reconfiguring the base layer portion can include separating the base layer portion based upon multiple components within the raw data; and forming base layer video frames from the multiple components.

  • Patent number: 9150498
    Abstract: The present invention discloses high yielding enantioselective process for synthesis of Oseltamivir from readily available starting material, cis-1,4-butene diol. The process features incorporation of chirality using sharpless asymmetric epoxidation (AE) and diastereoselective Barbier allylation and construction of cyclohexene carboxylic acid ester core through a ring closing metathesis (RCM) reaction. Further also disclosed herein is synthesis of (?)-methyl 3-epi-shikimate.
