Techniques for projecting images onto fabricated surfaces. One or more electronic files containing an engineering diagram that describes a three-dimensional shape of the fabricated surface are retrieved. Warp transformation information for transforming images to be projected onto the fabricated surface is calculated, based on the engineering diagram, positional information defining a three-dimensional position of a projection device, relative to the fabricated surface, and positional information of an intended viewer relative to the fabricated surface. The warp transformation information is applied to one or more images to generate one or more transformed images. Embodiments project, using the projection device, the one or more transformed images onto the fabricated surface.

A panoramic video playback method is provided, and the method includes: determining, by a client, that a user chooses to jump to play a video corresponding to a jump time point in a panoramic video; matching, by the client, the time point and a time range of each of at least one interest point included in the panoramic video; determining, by the client, a user's field of view in which an area of the matched interest point in a panoramic area of the panoramic video can be viewed; and obtaining, by the client, a video corresponding to the time point in the panoramic video, and jumping to play the video corresponding to the time point when the user's field of view is used.

An encoding apparatus comprises: a network interface for receiving an image; a memory for storing a command for encoding the image; and a processor for encoding the image according to the command, wherein the processor performs padding to set pixel values of a padding area corresponding to one edge area of the image by referring to the other edge area of the image adjacent to the one edge area on a sphere on which the image is projected, seeks a motion vector by referring to the pixel values of the padding area and encodes the image by referring to the motion vector, wherein the image is a 360-degree image.

Provided is a method of acquiring an optimized closed curved surface image using multiple cameras, and more particularly, an image providing method that produces a single image using a plurality of cameras fixed to a rig and having different capturing viewpoints, the method including projection operation of acquiring a single image by projecting images acquired from the plurality of cameras on a projection surface of a closed curved surface based on parameter information, rendering operation of fitting the acquired single image in a quadrangular frame for each region through a non-uniform sampling process, and viewing operation of mapping the sampled image to a viewing sphere.

A video processing method includes obtaining projection face(s) from an omnidirectional content of a sphere, and obtaining a re-sampled projection face by re-sampling at least a portion of a projection face of the projection face(s) through non-uniform mapping. The omnidirectional content of the sphere is mapped onto the projection face(s) via a 360-degree Virtual Reality (360 VR) projection. The projection face has a first source region and a second source region. The re-sampled projection face has a first re-sampled region and a second re-sampled region. The first re-sampled region is derived from re-sampling the first source region with a first sampling density. The second re-sampled region is derived from re-sampling the second source region with a second sampling density that is different from the first sampling density.

Example implementations described herein are directed to systems and methods for providing a panoramic video connection between one location and another, or between one location and a number of distributed remote viewers, which provides reciprocity in terms of awareness of who is viewing and what they are looking at. In example implementations described herein, radial displays present panoramic video from remote locations, or synthesized views of face shots positioned to indicate the viewing direction of remote viewers.
