A system of this invention is an all-around moving image distribution system for viewing an all-around moving image with realism. This all-around moving image distribution system includes an all-around camera, an all-around image generator that acquires an all-around moving image captured by the all-around camera, and generates time-series all-around frame image data, an all-around moving image data generator that encodes the time-series all-around frame image data, and generates all-around moving image data in a format reproducible in real time in a communication terminal apparatus, a distribution server that distributes, to the communication terminal apparatus, the all-around moving image data uploaded from the all-around moving image data generator, and an all-around moving image reproducer that reproduces, in real time, the all-around moving image data distributed from the distribution server, and displays a moving image of a range corresponding to a line-of-sight instruction by a user.

Embodiments of the present disclosure disclose a method and a device for adjusting a panoramic video 1. The method comprises: obtaining a gravity sensing parameter of an electronic device; calculating an included angle between a direction of the gravity sensing parameter and a negative axis of an x-axis, of the electronic device, wherein the included angle is an angle of which the direction of the gravity sensing parameter clockwise rotates to the negative axis of the x-axis: a panoramic model of a panoramic video is anticlockwise rotated by the angle relative to the negative axis of the x-axis to keep images of the panoramic video horizontal. By means of the method, the images of the panoramic video can be always kept horizontal.

A computing device, method and computer program product are provided to identify a feature. In a method, images are captured at different points in time and space and a reference plane is defined in a reference frame. The method includes applying image warping to map a plurality of reference points of a respective image in a sensor plane to corresponding reference points of the reference plane and mapping pixel coordinates for a plurality of pixels of the reference plane to the respective image based upon a positional relationship between the reference plane and a representation of the respective image established by having applied image warping to the respective image. The method further includes interpolating from pixels of the respective image to pixels at the pixel coordinates of the reference plane to generate an interpolated representation of the respective image that is then used to identify the feature within the scene.

Disclosed is an image display device or an image signal output device. The image display device or the image signal output device according to an exemplary embodiment of the present disclosure includes: a receiver for receiving an image; an input unit for receiving a user input to select a display mode or an image signal output mode; a determiner for determining the selected display mode; a depth map generator for generating a depth map for the received image having depth information corresponding to a predefined curvature if the result of determination indicates that the selected display mode is a 3D curved image mode; a 3D image frame generator for generating a left-eye image frame and a right-eye image frame from the received image on the basis of the generated depth map; and an output unit for outputting the generated left-eye image and right-eye image frames.

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.

The present technique provides a method of capturing a multi-viewpoint image of an object with a rotation axis of the object optionally changed by a user and an image display method. The present technique is a multi-viewpoint image capturing method including shooting an object from a plurality of different viewpoints, and capturing a plurality of still images, wherein the object is placed at a center of a virtually set ICO sphere, and during the shooting of the object, the images of the object are captured from a vertex of the virtually set ICO sphere toward the center of the ICO sphere such that the plurality of still images are generated.

The invention relates to a method of determining the sagittal rotation of a patient's pelvis based on a standard anterior posterior X-ray-image with known image parameters and a calibration of the image, for example by using at least one King-Mark calibration object. The angle of the pelvic rotation is determined between a pelvic plane which is orthogonal to the midsagittal plane of the pelvis, and the image plane of the X-ray-image. Assuming the patient's position shown on the X-ray-image represents a standard neutral position, the X-ray-image plane can be used as a functional reference plane for further calculations, for example during hip-replacement surgery. The present invention further relates to a corresponding computer program and system.
