Title:
SAMPLE ADAPTIVE OFFSET FILTERING METHOD FOR RECONSTRUCTED PROJECTION-BASED FRAME THAT EMPLOYS PROJECTION LAYOUT OF 360-DEGREE VIRTUAL REALITY PROJECTION
Document Type and Number:
WIPO Patent Application WO/2019/179489
Kind Code:
A1
Abstract:
A sample adaptive offset (SAO) filtering method for a reconstructed projection-based frame includes: obtaining at least one padding pixel (D0, D1, D2) in a padding area that acts as an extension of a face boundary (FB1) of a first projection face, and applying the SAO filtering to a block that has at least one pixel (PC) included in the first projection face. In the reconstructed projection-based frame, there is image content discontinuity between the face boundary (FB1) of the first projection face and a face boundary (FB2) of a second projection face. The at least one padding pixel (D0, D1, D2) is involved in the SAO filtering of the block.
