  • Patent number: 11265563
    Abstract: The disclosure lies in the field of coding image data, scalable in image resolution, such that one or more successive downsamplings are performed from a source signal of maximal image resolution to a minimal image resolution, in order to encode a base layer (L0) corresponding to this minimal resolution, the base layer (L0) serving as a reference for one or more enhancement layers (L1, L2) to be used for decoding at a terminal having a screen of higher image resolution than the minimal image resolution. From said successive downsamplings, the base layer (L0) and the one or more enhancement layers (L1, L2) are constructed, and then an encoded bit stream is prepared in order to be transmitted, comprising data of the base layer and of the enhancement layer or layers. In particular, the downsampling step comprises the application of an adaptive low-pass filter to the image data from the downsampling.

  • Patent number: 10402954
    Abstract: Disclosed systems and methods perform histogram-based shape mapping for propagating changes across similar shapes in multiple artboards. An image processing application executed by one or more processing devices accesses a first shape to be displayed in a master artboard and a second shape to be displayed in a child artboard. The image processing application computes a first histogram for the first shape and a second histogram for the second shape. The image processing application maps the first shape to the second shape based on a level of similarity between the first and second histograms. The image processing application detects a change to the first shape in the master artboard. The image processing application propagates the change to the second shape in the child artboard based on the first shape being mapped to the second shape.

  • Patent number: 10359518
    Abstract: Embodiments relate to methods for efficiently encoding sensor data captured by an autonomous vehicle and building a high definition map using the encoded sensor data. The sensor data can be LiDAR data which is expressed as multiple image representations. Image representations that include important LiDAR data undergo a lossless compression while image representations that include LiDAR data that is more error-tolerant undergo a lossy compression. Therefore, the compressed sensor data can be transmitted to an online system for building a high definition map. When building a high definition map, entities, such as road signs and road lines, are constructed such that when encoded and compressed, the high definition map consumes less storage space. The positions of entities are expressed in relation to a reference centerline in the high definition map. Therefore, each position of an entity can be expressed in fewer numerical digits in comparison to conventional methods.
