    Abstract: Provided is an electronic device for stabilizing a 360-degree video, the electronic device including a memory storing one or more instructions, and a processor for executing the one or more instructions stored in the memory, wherein the processor is configured to execute the one or more instructions to: when a 360-degree video is reproduced, allocate probability values to a plurality of pixels included in a frame of the 360-degree video, based on a possibility that each of the plurality of pixels is included in a user's field of view (FOV), determine a three-dimensional (3D) rotation for the 360-degree video, based on the allocated probability values, and generate a stabilized 360-degree video by applying the 3D rotation to the 360-degree video.

    Abstract: Apparatus and methods are provided. The method includes receiving content that comprises at least one 360 degree image. The method also includes applying a rotation to the at least one 360 degree image to increase a compression ratio, when a compression algorithm compresses the at least one 360 degree image that is rotated, relative to another compression ratio achieved when the compression algorithm compresses the content without the applied rotation to the at least one 360 degree image. The method also includes compressing the content including the at least one 360 degree image that is rotated based on the compression algorithm. The method further includes outputting the compressed content and a rotation parameter that defines the applied rotation.

    Abstract: An image processing method is disclosed, comprising comparing a first image and a modified second image, the modified second image comprising a copy of the first image in which at least one pixel value of one or more pixels have been modified, and based on the result of the comparison, generating first image reconstruction information which can be combined with the modified second image to reconstruct the first image. A corresponding image reconstruction method comprises combining the image reconstruction information with the modified second image to reconstruct the first image. Apparatus for implementing the methods is also disclosed.
