The parameter is calibrated by calculating a gradient of one characteristic curve of the light barrier and readjusting the parameter to a target value calculated based on the gradient. |

A unified channel contention scheme is proposed such that spatial reuse can be enabled by a wireless station (STA) when a basic service set (BSS) color of a received signal cannot be resolved.

Detection of motion activity saliency in a video sequence
A streaming video or a stored video is analyzed to identify salient features. The salient features are the more interesting portions of the video because salient features include the most motion. A motion vector field including a motion vector for multiple pixels in the video is generated. The motion vector field is partitioned into grid blocks, and each of the grid blocks is divided into a set of orientation ranges. The vectors of the motion vector field for each grid block are binned into the orientation ranges. A motion score is calculated based on a count of motion vectors for the orientation ranges. The section of the video having higher or the highest motion score is designated as a salient feature. Among other applications, salient features may be used for thumbnail images, highlight reels, or video editing. |

Residual colour transform signalled at sequence level for specific coding modes
The present invention is related to video coding and decoding, in particular HEVC RExt that define the adaptive residual color transform, Adaptive RCT, of a residue of pixels. Compared to HEVC RExt where Adaptive RCT is signalled at Coding Unit level, embodiments of the invention propose to signal it in the bitstream in association with two or more coding units forming the image. In other words, it is signalled at a level higher than the CU level, for instance at sequence or frame or slice or tile or coding tree block level. In addition, various flags at this higher level make it possible to generically define the applying or not of RCT for various respective coding modes, for instance Inter coding mode, Intra Block Copy coding mode or Intra coding mode where Chroma and Luma modes are the same. Such approach makes it possible to reduce the amount of evaluations to be performed. |

Decorrelated channel sampling for digital imaging
In association with an imaging device which generates a portion of an image from a plurality of channels within a first row by sampling each channel during a sampling time corresponding to the channel, circuitry offsets sampling times of at least first and second channels within the first row, thereby reducing noise correlation between the first and second channels in the first row. Pixel sampling times may be defined by start times of the channels within a row, end times or both. Offsetting may be accomplished using a predetermined set of sampling time values or by randomizing sampling time values. Offsetting pixel sampling times of channels within a row relative to each other decorrelates channel sampling because different phases of the noise signal are sampled on each channel, effectively blurring or dithering the channel noise within each row. Random sampling within the channel, such as by varying a channel sampling time between rows, further dithers the noise within each channel. Undesirable correlated noise effects are reduced as a result. |

Electronic mail data modeling for efficient indexing
Techniques are herein described for creating a scalable IMAP4 compliant email system using a NoSQL database and a distributed full text search engine. Data for each email message is stored in multiple tables to avoid storing redundant data unnecessarily. However, a full text search index is created based on a single table as if the index refers to a single table. In embodiments herein described, the single index is created on the fields of a message metadata table with virtual fields added to the table that are derived from the message content. During this process, data is pulled from a message table in “blob” format and broken down into corresponding fields and data items, so the data items may be converted and placed in the proper virtual fields for index creation. Each blob section that is converted is cached, so the same blob section does not need to be converted multiple times. After index creation, the index may be used to search for emails based on metadata and data within the body of the email. |
