Method and apparatus for providing 360 stitching workflow and parameter

An image stitching workflow creation apparatus for creating an image stitching workflow, the image stitching workflow apparatus comprising one or more processors and one or more memory devices,

• wherein the one or more processors perform one or more instructions of a program for creating the image stitching workflow stored in the one or more memory devices,
• wherein the one or more memory devices stores the program for creating the image stitching workflow, and
• wherein the one or more instructions include:
• acquiring 360-degree virtual reality (VR) image workflow descriptors necessary to make a request for image stitching and create the image stitching workflow;
• acquiring function descriptors applicable to the image stitching workflow from a function registry;
• creating the image stitching workflow based on the function descriptors selected from the function registry;
• determining configurations of media processing entities necessary to perform tasks for the image stitching workflow based on the 360-degree VR image workflow descriptors;
• configuring a plurality of media processing entities according to the configurations of media processing entities;
• and
• allocating the tasks configuring the image stitching workflow to the plurality of media processing entities,
• wherein the function descriptors include configuration parameters, and
• wherein the configuration parameters include a feature parameter, a camera parameter, a projection parameter, and a stitching parameter,
• wherein the feature parameter includes a feature extraction method parameter indicating a method to extract features,
• wherein the camera parameter includes at least one of a focal length parameter, a principal point parameter, a camera skew value parameter, or a camera transformation parameter,
• wherein the projection parameter includes a projection type parameter, and
• wherein the stitching parameter includes at least one of a seam position parameter or a seam mask parameter.
