  • Patent number: 11042770
    Abstract: An image data processing method includes receiving first frame image data at a first resolution, reducing a resolution of the first frame image data to a second resolution, performing image recognition on the first frame image data to determine one or more regions of interest (ROI) and a priority level of each of the ROIs; receiving second frame image data, and extracting portions of the second frame image data corresponding to the one or more ROIs. The method further includes modifying a resolution of the portions of the second frame image data corresponding to the ROIs based on the priority level of the ROIs, reducing a resolution of the received second frame image data to the second resolution, and combining the resolution-modified portions of the second frame image data corresponding to the ROIs with the second frame image data at the second resolution to generate output frame image data.

  • Publication number: 20210042327
    Abstract: Disclosed herein is the creation of probabilistic data structures for container reclamation. One method involves retrieving a segment object list of a data container and creating a probabilistic data structure. The segment object list comprises a plurality of segment objects, the data container comprises the plurality of segment objects and a plurality of data objects, and each segment object of the plurality of segment objects comprises a hash value determined by performing a hashing function on a corresponding data object of the plurality of data objects. The creating includes, for each segment object in the segment object list, identifying an element of a plurality of elements of the probabilistic data structure using a hash value of the each segment object and setting the element to indicate the segment object references a corresponding data object of the plurality of data objects.

  • Patent number: 10846301
    Abstract: Disclosed herein are methods, systems, and processes to perform container reclamation using probabilistic data structures. A hash value associated with a data segment and stored in a data container is received. Elements in a probabilistic data structure are identified using one or more portions of the hash value and element values are determined for each element. In response to a determination that the element values indicate that the segment object should be maintained, the segment object is maintained during compaction of the data container.
