Aspects of the present disclosure provide mechanisms for fast hyper frame number (HFN) resynchronization of Packet Data Convergence Protocol (PDCP) Protocol Data Units (PDUs). A wireless communication device (e.g., a PDCP entity at a wireless communication device) can calculate a current PDCP count of a current PDCP PDU of a plurality of PDCP PDUs received from a radio link control (RLC) sublayer based on a PDCP sequence number (SN) of the current PDCP PDU and an HFN of a first missing PDCP PDU after a successfully received PDCP PDU. The PDCP count may be calculated using the HFN of the first missing PDCP PDU in response to a gap between the PDCP count of the first missing PDCP PDU and the actual PDCP count of the current PDCP PDU being greater than a PDCP window size.

A power network includes a plurality of power switch units disposed in a first semiconductor layer, arranged in a plurality of columns along a first direction and a plurality of rows along a second direction. The power switch units in even rows are aligned with a center point of a horizontal space between adjacent two of the power switch units in the same row of the odd rows of the power switch units in the first direction. The power switch units in even columns are aligned with a center point of a vertical space between adjacent two of the power switch units in the same column of the odd columns of the power switch units in the second direction. The power network further includes a plurality of second connecting lines disposed in a fourth semiconductor layer and extending in the second direction.

Some embodiments of the present disclosure provide a method for generating video mask information, a method for preventing occlusion from barrage, a server and a client. The method for generating video mask information comprises: identifying, for any video frame in the video data to be parsed, an area where a target object is located in the video frame; selecting a plurality of geometric figures to fit the area where the target object is located, to allow a combination of the plurality of geometric figures to cover the area where the target object is located; and generating the mask information of the video frame according to a fitting parameter of the plurality of geometric figures, and sending the mask information and data of the video frame to a client synchronously. Some embodiments of the present disclosure are adopted to avoid occlusion caused by the barrage information on the video image while the vast majority of the barrage information remains and reducing a bandwidth consumption of the client.

Part of the present application provides a method, system and device for fitting a target object in a video frame. The method comprises: identifying a region where the target object is located in the video frame; selecting one or more geometric figures to fit the region where the target object is located, such that a combination of the one or more geometric figures covers the region where the target object is located; and generating a fitting parameter for each of the geometric figures according to a type of the geometric figure and a layout parameter of the geometric figure in the video frame, and taking a combination of the fitting parameters of respective geometric figures as a fitting parameter of the video frame. With the embodiments of the present application, the data amount after fitting is reduced, thereby improving efficiency of subsequent processes.

A video enhancement system provides automatic enhancement to video data that includes the presence of obscurations. The system provides near-field enhancement of the video data by detecting the presence of near-field obscurations such as snowflakes/raindrops and determining whether the detected obscurations are located over background pixels or foreground objects. The detected obscuration pixels are filled-in depending on whether they are located over the background or foreground to create an enhanced image. The system may also provide local/global adaptive contrast enhancement to enhance video in the presence of far-field obscurations.

System and method for video-quality enhancement

A video-based object recognition system and method provides selective, local enhancement of image data for improved object-based recognition. A frame of video data is analyzed to detect objects to receive further analysis, these local portions of the frame being referred to as a region of interest (ROI). A video quality metric (VQM) value is calculated locally for each ROI to assess the quality of the ROI. Based on the VQM value calculated with respect to the ROI, a particular video quality enhancement (VQE) function is selected and applied to the ROI to cure deficiencies in the quality of the ROI. Based on the enhanced ROI, objects within the defined region can be accurately identified.
