Patents by Inventor Zhiying Guo

Zhiying Guo has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10664980
    Abstract: Systems, methods, apparatuses, and software for vector graphics object handling in computing environments are provided herein. In one example, an object handling service for a user application is provided that identifies an object in a scalable vector graphics format for import into the user application, parses a description of the object in the scalable vector graphics format to determine shape components that comprise the object, and iterates through each of the shape components to generate freeform shape primitives that recreates the object into a native object description of the user application.
    Type: Grant

  • Patent number: 9135723
    Abstract: Systems, methods, and other embodiments associated with efficient visually lossless compression are described. According to one embodiment, an apparatus includes a transform logic configured to receive image data divided into segments and generate a matrix of transform coefficients corresponding to a segment. The apparatus also includes a rate control logic configured to select (i) a set of quantization levels from a plurality of sets of quantization levels and (ii) a quantization level from the selected set of quantization levels based, at least in part, on a desired visual quality. Each set of quantization levels corresponds to a different target compression ratio for the image data. The apparatus further includes a quantization logic configured to quantize the matrix of transform coefficients according to the selected quantization level to produce an array of integers. The apparatus also includes an encoding logic configured to encode the array of integers as a bit stream.
