Abstract
Methods and apparatus of processing cube face images are disclosed. According to embodiments of the present invention, one or more discontinuous boundaries within each assembled cubic frame are determined and used for selective filtering, where the filtering process is skipped at said one or more discontinuous boundaries within each assembled cubic frame when the filtering process is enabled. Furthermore, the filtering process is applied to one or more continuous areas in each assembled cubic frame.

A method of processing cube face images, the method comprising:
- receiving sets of six cubic faces converted from spherical images in a 360-degree panoramic video sequence, wherein each set of six cubic faces corresponds to one spherical image projected onto a cube for rendering 360-degree virtual reality;
- assembling each set of cubic faces into one assembled cubic frame according to a selected cubic face format;
- determining one or more discontinuous boundaries within each assembled cubic frame;
- and
- processing the assembled cubic frames according to information related to said one or more discontinuous boundaries, wherein said processing the assembled cubic frames comprises:
- skipping filtering process at said one or more discontinuous boundaries within each assembled cubic frame when the filtering process is enabled.
An apparatus for processing cube faces, the apparatus comprising one or more electronic circuits or processor arranged to:
- receive sets of six cubic faces converted from spherical images in a 360-degree panoramic video sequence, wherein each set of six cubic faces corresponds to one spherical image projected onto a cube for rendering 360-degree virtual reality;
- assemble each set of cubic faces into one assembled cubic frame according to a selected cubic face format;
- determine one or more discontinuous boundaries within each assembled cubic frame;
- and
- process the assembled cubic frames according to information related to said one or more discontinuous boundaries, wherein said processing the assembled cubic frames comprises:
- apply filtering process to one or more continuous areas in each assembled cubic frame and skipping the filtering process at said one or more discontinuous boundaries within each assembled cubic frame.
