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.

Accordingly embodiments herein disclose a method for producing 360 degree image content on a rectangular projection. The method includes detecting whether at least one discontinuous boundary is present in the 360-degree image content, wherein the at least one discontinuous boundary is detected using the packing of one or more projection segments. Further, the method includes obtaining one or more reconstructed blocks from the 360-degree image content. The reconstructed blocks are generated from the 360 degree image content. Further, the method includes performing one of enabling at least one in-loop filtering function on the one or more reconstructed blocks of the 360 degree image content when the at least one of image content discontinuous boundary is not present and disabling at least one in-loop filtering function on the one or more reconstructed blocks of the 360 degree image content located around the at least one discontinuous boundary.

The present disclosure proposes an image processing method according to an embodiment. The image processing method includes the operations of obtaining a color component value from an input image, determining a dynamic range of the obtained color component value, determining a scaling factor for converting the dynamic range of the color component value, based on the determined dynamic range of the color component value and a permissible range of the color component value, and scaling the color component value, based on the determined scaling factor.
