Disclosed herein are systems and methods for correcting distortion in a camera lens. The methods can include receiving at least one image of a calibration object, in which the image is captured via the camera lens and the lens has lens distortion. The methods can further include fitting a plurality of geodesics in the image; determining at least one connection equation for the plurality of geodesics; and determining a metric based on the connection equation, the metric comprising a first distorted radial coordinate. The methods can further include determining an undistorted radial coordinate based on the first distorted radial coordinate; determining a second distorted radial coordinate as a function of the undistorted radial coordinate; inverting the undistorted radial coordinate; and generating an undistorted image based on the inverted undistorted radial coordinate.

Hyper-hemispherical images may be combined to generate a rectangular projection of a spherical image having an equatorial stitch line along of a line of lowest distortion in the two images. First and second circular images are received representing respective hyper-hemispherical fields of view. A video processing device may project each circular image to a respective rectangular image by mapping an outer edge of the circular image to a first edge of the rectangular image and mapping a center point of the circular image to a second edge of the first rectangular image. The rectangular images may be stitched together along the edges corresponding to the outer edge of the original circular image.

Methods and devices are provided to encode points of a sphere onto an image by projecting them as a function of an isotropic region guided mapping operator and/or to decode pixels of an image onto a sphere by de-projected them according to the same parametrized mapping operator. A region of interest is determined on the sphere and the angular resolution of pixels of the image is modulated as a function of their distance to the reference pixel corresponding to the center of the region of interest. Chosen angular resolutions and size of the region of interest are associated with the image and encoded in a stream.

A method of and an apparatus for processing a 360 degree video are provided. The method includes determining an interest object in the 360 degree video, based on user information indicating the interest object, determining a target viewing area around the interest object, in the 360 degree video, and processing the target viewing area while refraining from processing a remaining viewing area excluding the target viewing area, in the 360 degree video.

A video may include a capture of a scene, such as a wide-field of view capture of the scene. A punchout of the video may provide a framing of the captured scene. The punchout may be determined based on the context of the video, such as the type of captured scene within the video, the motion of the image capture device that captured the video, and/or the motion of one or more things within the captured scene.
