A system and method for improving the quality of video for virtual reality systems uses several different techniques to improve the quality of the video. The different techniques may include quantization parameter maps, gradient scaling, using analytics to identify most view scenes and encode the most viewed scenes with better quality and adaptively shaping the field of view.

Video quality improvements system and method for virtual reality

A low-complexity method and apparatus for frame accurate field of view switching for virtual reality systems may be used principally for streaming virtual reality data systems, allowing optimal and consistent quality for field of view based VR streaming engines. The method and apparatus may also be used for other virtual reality data systems.

Method and apparatus for frame accurate field of view switching for virtual reality

An apparatus and method for improving the quality of user experience and reducing bandwidth consumption in Virtual Reality systems that optimize bandwidth by restricting the transmitted stream to only what is in the field of view of a virtual reality headset are disclosed. The actual content streamed may vary from interactive games to pre-recorded or live video.

Method and apparatus for improving quality of experience and bandwidth in virtual reality streaming systems

A partial evaluator system and method are disclosed. The disclosure may be particularly applicable to partial evaluation in image and video signal processing. The partial evaluation system and method also may be used for other signal processing methods and may be used, more generally, for other complicated processing operations.

Partial evaluator system and method

A system and method for frequency reduction and restoration. The system and method may be used to reduce the visual redundancy in digital data, such as in video data and image data.

Frequency reduction and restoration system and method in video and image compression

Transform system and method in video and image compression

A system and method that reduce or eliminate step-contouring generated by compression algorithms are provided because many types of compression algorithms introduce a step-contoured artifact for images and video with slow gradients. The system and method restores the gradient to a piece of content by detecting a start and end of the step contour in each row and column of the piece of content and increments a pixel in certain regions of the row or the column to restore the gradient in the piece of content.

Artifact removal method and system for contoured images and video

A system and method that reduce or eliminate the compression artifact of step-contouring in a piece of content having a gradient are provided because many types of compression algorithms introduce a step-contoured artifact for images and video with slow gradients. An artifact removal unit detects the start and end of a step contour, determines a gradient of the step contour and increments a pixel in certain regions to restore the gradient.

A bidirectional radio frequency identification (RFID) network system and method are presented. The system allows users to configure, monitor, and manage different sensor devices by using a graphical user interface real-time. The reconfiguration is done through a network management computer at the top system level that receives user input, generates code images according to the user input, and appropriately routes the code images to sensor routers that directly control the sensors. If the system is multi-layered, some code images are also sent to the intermediate-level network management computers. The system allows users to not only monitor a business flow but react to problematic situations quickly by adjusting the workflow. The aspect-oriented nature of the system allows users to reconfigure the system based only the Functionality aspects without worrying about the Partitioning aspects (e.g., how the network and the sensors are physically connected).

Radio frequency identification (RFID) network system and method

To generate computationally efficient computer program code for carrying out computer computations on matrix organized input data, a program first is written in a relatively high-level language which includes programmer specifiable constructs for manipulating matrices and parts thereof; and which permits certain of the constructs to be annotated to specify programmer selected data structures and programmer selected operations on those data structures. This high-level program then is translated into a relatively high-level program into a relatively low-level language using low-level language routines that provide a compilable representation of the program, including all programmer selected data structures and all programmer selected operations on said data structures then the low-level representation of the program is compiled to generate computer executable code for implementing the program, including all programmer selected data structures and all programmer selected operations on said data structures.
