    Abstract: A system includes sensors and a tracking subsystem. The subsystem receives a first image feed from a first sensor and a second image feed from a second sensor. The field-of view of the second sensor at least partially overlaps with that of the first sensor. The subsystem detects, in a frame from the first feed, a first contour associated with an object. The subsystem determines, based on pixel coordinates of the first contour, a first pixel position of the object. The subsystem detects, in a frame from the second feed, a second contour associated with the same object. The subsystem determines, based on pixel coordinates of the second contour, a second pixel position of the object. Based on the first pixel position and the second pixel position, a global position for the object is determined in a space.

  • Patent number: 10771849
    Abstract: A method for multimedia playback and transmission to wireless clients is described. A host webserver transcodes a live digital or analog audio-visual or audio broadcast signal and splits the input stream into small multimedia objects of an efficient compression such as MPEG4/AAC, and then immediately deploys the objects to distributed content servers for a geographically dispersed population of wireless clients. A java applet object player, downloaded to wireless clients at the beginning of the multimedia on-demand session, interprets and decodes the multimedia objects as they are received, using multiple levels of optimization. The applet uses novel video and audio decoding optimizations which can be generically applied to many digital video and audio codecs, and specifically decodes Simple Profile MPEG4 video and Low Complexity AAC audio.

The SC block estimates an error in each category as difference between a deblocked pixel of the set of deblocked pixels and corresponding original pixel of the set of original pixels. The RDO block determines a set of candidate offsets associated with each category and selects a candidate offset with a minimum RD cost. The minimum RD cost is used by a SAO type block and a decision block to generate final offsets for the SAO encoder.

  • Patent number: 10504259
    Abstract: Video or graphics, received by a render engine within a graphics processing unit, may be segmented into a region of interest such as foreground and a region of less interest such as background. In other embodiments, an object of interest may be segmented from the rest of the depiction in a case of a video game or graphics processing workload. Each of the segmented portions of a frame may themselves make up a separate surface which is sent separately from the render engine to the display engine of a graphics processing unit. In one embodiment, the display engine combines the two surfaces and sends them over a display link to a display panel. The display controller in the display panel displays the combined frame. The combined frame is stored in a buffer and refreshed periodically.

  • Patent number: 10462494
    Abstract: Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.

  • Patent number: 10410408
    Abstract: Graphics processing systems can include lighting effects when rendering images. “Light probes” are directional representations of lighting at particular probe positions in the space of a scene which is being rendered. Light probes can be determined iteratively, which can allow them to be determined dynamically, in real-time over a sequence of frames. Once the light probes have been determined for a frame then the lighting at a pixel can be determined based on the lighting at the nearby light probe positions. Pixels can then be shaded based on the lighting determined for the pixel positions.
