  • Publication number: 20170300505
    Abstract: In one example an updated snapshot delta value is computed upon occurrence of a new transaction. The new transaction is a data modification operation performed on data blocks of the storage device. Further, the delta value indicates at least one of volume of data modified since creation of a reference snapshot and number of transactions performed since the creation. Subsequently, the updated snapshot delta value is compared with a corresponding threshold value. The threshold value is at least one of a predetermined volume of data modified and a predetermined number of transactions. A snapshot action is subsequently performed based on the comparison.

  • Patent number: 9734588
    Abstract: A method and system is provided for the compression of a video captured from a static camera. A background image and an original image is captured from the static camera. A foreground object is extracted by taking the difference between the transformed original image and the transformed background image. The foreground object is represented as a sparse vector using wavelets. The method revolves around the compressive sensing framework by ingeniously using the complex field BCH codes and the syndrome as measurements to achieve robust background subtraction using reduced number of measurements. The reconstruction is carried out by a Complex-field BCH decoder coupled with block based implementation. According to another embodiment, an adaptive techniques has also been proposed for acquiring the measurements required for recovering the images.

  • Patent number: 9116827
    Abstract: A system(s), method(s) and computer program product to optimize Luby Transform codes to facilitate a transmission of data over a communication network are disclosed. Demands from various sinks are received and a demand vector is calculated. Various sources are employed with LT codes to encode the data. A Generalized LT code (GLT) is generated for an objective function determined for a given demand vector irrespective of the LT codes employed at the sources. Morphing rules are designed by optimizing a degree distribution of the data and mapping LT codes to the generalized LT codes. The GLT is optimized by using a linear transformation to obtain optimal morphing rules. The LT codes are retargeted by re-encoding an LT encoded data to further obtain an LT re-encoded data. The LT re-encoded data is then transmitted by a relay device to plurality of sinks.
