Provided are a method and an apparatus for determining an optimal rotation angle during compression of a spherical multimedia content where the processor may receive first multimedia content corresponding to the spherical multimedia content, generate a plurality of second multimedia contents based on the first multimedia content by rotating the first multimedia content to a plurality of rotation angles, perform an edge analysis on each of the plurality of the second multimedia contents, identify the number of edges aligned to one of a vertical axis or a horizontal axis based on the edge analysis, select second multimedia content with the maximum number of edges, and determine an optimal rotation angle.

Methods and apparatus for determining rotation angle for spherical multimedia content

Provided are methods and apparatus for determining an adjustment parameter during encoding of a spherical multimedia content which comprises finding the region of maximum concentrated energy is concentrated in the generated energy map of the spherical multimedia content, measuring the width of the maximum concentrated energy region in the generated energy map, and deriving optimal adjustment parameter from the width of the maximum concentrated energy region in the generated energy map.
