A video processing method includes receiving a reconstructed frame, and applying in-loop filtering, by at least one in-loop filter, to the reconstructed frame. The step of in-loop filtering includes performing a sample adaptive offset (SAO) filtering operation. The step of performing the SAO filtering operation includes keeping a value of a current pixel unchanged by blocking the SAO filtering operation of the current pixel included in the reconstructed frame from being applied across a virtual boundary defined in the reconstructed frame.

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.

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.

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.
