Abstract: Methods and apparatus of coding a video sequence, wherein pictures from the video sequence contain one or more discontinuous edges are disclosed. The loop filtering process associated with the loop filter is then applied to the current reconstructed pixel to generate a filtered reconstructed pixel, where if the loop filtering process is across a virtual boundary of the current picture, one or more alternative reference pixels are used to replace unexpected reference pixels located in a different side of the virtual boundary from the current reconstructed pixel, and said one or more alternative reference pixels are generated from second reconstructed pixels in a same side of the virtual boundary as the current reconstructed pixel. According to another method, reference pixels are derived from spherical neighbouring reference pixels for the loop filtering process.

Abstract: A mesh rendering system, a mesh rendering method and a non-transitory computer readable medium are provided. The mesh rendering system includes a database, a user device and a server. The server obtains preprocessing data of a cloth and a rigidbody according to initial mesh state of the cloth, initial mesh state of the rigidbody and motion of the rigidbody, wherein the cloth and the rigidbody are deformable and motion of the cloth corresponding to the motion of the rigidbody is a small deformation. The server stores the preprocessing data in the database. A finite state machine of the server receives a real-time input data from the user device through a web service and the preprocessing data, and the finite state machine outputs a deformation result of the cloth and the rigidbody to the user device through a handshake mechanism.

Abstract: A sample adaptive offset (SAO) filtering method for a reconstructed projection-based frame includes: obtaining at least one padding pixel in a padding area that acts as an extension of a face boundary of a first projection face, and applying SAO filtering to a block that has at least one pixel included in the first projection face. In the reconstructed projection-based frame, there is image content discontinuity between the face boundary of the first projection face and a face boundary of a second projection face. The at least one padding pixel is involved in the SAO filtering of the block.

Abstract: Methods and apparatus of processing 360-degree virtual reality (VR360) pictures are disclosed. A target reconstructed VR picture in a reconstructed VR picture sequence is divided into multiple processing units and whether a target processing unit contains any discontinuous edge corresponding to a face boundary in the target reconstructed VR picture is determined. If the target processing unit contains any discontinuous edge: the target processing unit is split into two or more sub-processing units along the discontinuous edges; and NN processing is applied to each of the sub-processing units to generate a filtered processing unit. If the target processing unit contains no discontinuous edge, the NN processing is applied to the target processing unit to generate the filtered processing unit. A method and apparatus for CNN training process are also disclosed. The input reconstructed VR pictures and original pictures are divided into sub-frames along discontinuous boundaries for the training process.

Abstract: A de-blocking method is applied to a reconstructed projection-based frame having a first projection face and a second projection face, and includes obtaining a first spherical neighboring block for a first block with a block edge to be de-blocking filtered, and selectively applying de-blocking to the block edge of the first block for at least updating a portion of pixels of the first block. There is image content discontinuity between a face boundary of the first projection face and a face boundary of the second projection face. The first block is a part of the first projection face, and the block edge of the first block is a part of the face boundary of the first projection face. A region on a sphere to which the first spherical neighboring block corresponds is adjacent to a region on the sphere from which the first projection face is obtained.

Abstract: An adaptive loop filtering (ALF) method for a reconstructed projection-based frame includes: obtaining at least one spherical neighboring pixel in a padding area that acts as an extension of a face boundary of a first projection face, and applying adaptive loop filtering to a block in the first projection face. In the reconstructed projection-based frame, there is image content discontinuity between the face boundary of the first projection face and a face boundary of a second projection face. A region on the sphere to which the padding area corresponds is adjacent to a region on the sphere from which the first projection face is obtained. The at least one spherical neighboring pixel is involved in the adaptive loop filtering of the block.

Abstract: A pharmacological composition for use in inhibiting differentiation, functional activities, and population of granulo-cytic myeloid-derived suppressor cells (gMDSCs) and/or suppressing, tumor metastasis in a subject in need thereof is disclosed. The composition comprises a therapeutically effective amount of Bidens pilosa extract, or more than one polyacetylenic compounds purified or isolated from the B. pilosa extract, and a pharmaceutically acceptable carrier.

Abstract: An anti-disassembly protection structure includes a cover, a base, and a moving member. The cover includes a circuit board. The moving member includes a connecting part and at least one conducting part. The connecting part defines a plurality of receiving holes to receive the at least one conducting part.

When the cover is moved out of the base, the moving member moves towards a second direction opposite to the first direction. The at least one conducting part is moved away from the circuit board and is out of the plurality of receiving holes.

Abstract: An anti-tamper device for preventing data from being tampered with by an unauthorized person includes a top cover, a bottom cover, a printed circuit board (PCB), and a signal connector. The bottom cover is assembled to the top cover. The PCB has a plurality of terminal couplers.

When the terminals are not connected to the corresponding terminal couplers, a second relation signal different from the first relation signal is generated by the PCB to make the anti-tamper device unable to work.

Abstract: An exemplary electronic device includes a front wall and a protecting member. The font wall includes a socket used to engagingly receive a plug and a fixing member used to fix the front wall to a side wall associated with the electronic device. The protecting member is located between the socket and the fixing member and slidably attached to the front wall to selectively shield at least part of the socket or shield the fixing member. When the protecting member shields at least part of the socket, the fixing member is exposed to allow the front wall to be disassembled from the side wall. When the protecting member shields the fixing member, the socket is entirely exposed to allow the plug to be inserted into the socket.
