A video system processes video frames from a wide angle camera to dewarp the video frames in a manner that preserves conformity of an object of interest. A crop region of a video frame corresponding to the object of interest is determined. An input parameter to a dewarping function is generated based on the detected crop region. The dewarping function is applied to the crop region using the input parameter to generate a dewarped video frame and the dewarped video frame is outputted. The input parameter may be generated in a manner that causes the dewarped video frame to have higher conformity and lower distortion in the region around the object of interest than in a region distant from the object of interest.

A video processing method includes: decoding apart of a bitstream to generate a decoded frame, where the decoded frame is a projection-based frame that includes projection faces in a projection layout; and remapping sample locations of the projection-based frame to locations on the sphere, where a sample location within the projection-based frame is converted into a local sample location within a projection face packed in the projection-based frame; in response to adjustment criteria being met, an adjusted local sample location within the projection face is generated by applying adjustment to at least one coordinate value of the local sample location within the projection face, and the adjusted local sample location within the projection face is remapped to a location on the sphere; and in response to the adjustment criteria not being met, the local sample location within the projection face is remapped to a location on the sphere.

A method and an electronic apparatus for stitching a three-dimensional spherical panorama are provided. The method includes: obtaining a first image and a second image; projecting the first and seconds image onto a virtual spherical plane to form a first equirectangular panorama and a second equirectangular panorama; duplicating the first equirectangular panorama to generate a third equirectangular panorama, and duplicating the second equirectangular panorama to generate a fourth equirectangular panorama; performing image enhancement on the third and fourth equirectangular panoramas to generate a first enhanced equirectangular panorama and a second enhanced equirectangular panorama; calculating an optical flow for the first and second enhanced equirectangular panoramas; generating the three-dimensional spherical panorama according to the first and second equirectangular panoramas and the optical flow. The method and the electronic apparatus for stitching the three-dimensional spherical panorama may stitch, into the three-dimensional spherical panorama, images output by a radially designed panoramic camera.

Examples are disclosed relating to applying an analytical geometric projection that has been modified by an amplitude function. One example provides a computing device comprising a logic subsystem and a storage subsystem holding instructions executable by the logic subsystem to receive an image of a scene as acquired by an image sensor, apply a mapping to the image of the scene that maps pixels of the image to projected pixels on an analytical projection that is modified by an amplitude function such that the analytical projection achieves a higher zoom effect on pixels closer to a center of the image compared to pixels closer to an edge of the image, thereby obtaining a corrected image, and output the corrected image.

An image capture device may capture two hemispherical views of a scene. The two hemispherical view of the scene may be stitched along a stitch line. The image capture device may be rotated to align the stitch line with a mid-line of a panoramic field of view of the scene. Separate exposure settings may be used to capture the two hemispherical views of the scene, with the exposure settings increasing the dynamic range of the scene depicted within the panoramic field of view of the scene. The panoramic field of view of the scene may be punched out as panoramic visual content.

Two image processing systems and an image processing method are provided. One of the image processing systems includes a first unit configured to output a portion of input image data, a second unit configured to transform a coordinate of input image data, and a third unit configured to output the image data processed by the first unit and the second unit as video data to be displayed on a display. The other one of the image processing system further includes a fourth unit configured to combine input image data of a plurality of images to output one piece of image data. The image processing method includes outputting a portion of input image data, transforming a coordinate of input image data, and outputting the image data as video data to be displayed on a display.

Disclosed is a system (100) for processing images related to a target region. The system comprises a memory (102) and a computing arrangement (104) in communication with the memory. The computing arrangement is configured to define one or more target buffers (106) in the memory of a size corresponding to one or more image parameters to be used as an input to a model implemented for the processing the images. The computing arrangement is further configured to receive at least one image (300, 400A, 400B, 400C, 400D) of the target region from a wide-angle camera (108, 202), define two or more virtual camera views (302, 304, 306, 412, 416, 418, 420, 422) and process the at least one image to generate two or more virtual images (308, 310, 312, 400E) based on the defined one or more target buffers and the defined two or more virtual camera views. The computing arrangement is further configured to implement the said model to analyse the generated two or more virtual images.

An image processing device includes: a determination means for determining an image capturing means used for capturing at least one particular portion in a combined image in which a first partial image captured using a first image capturing means and a second partial image captured using a second image capturing means are stitched together; and a correction means for applying image correction to the combined image based on a determination result of the determination means.

The information processing system obtains a plurality of images based on image capturing by a plurality of imaging devices; obtains viewpoint information for specifying a position of a virtual viewpoint and a view direction from the virtual viewpoint; and generates a plurality of virtual viewpoint contents each of which corresponds to one of a plurality of image formats based on the common plurality of obtained images and the obtained viewpoint information, and the plurality of image formats is image formats whose numbers of virtual viewpoints specified by the viewpoint information used for generation of the virtual viewpoint contents are different from one another.

A display control device includes a vehicle detection unit and an image processing unit, the image processing unit generating a rearward image of a vehicle, setting in the rear image a boundary region for blending the pixel values of two adjacent photographic images, and changing the position and width of the boundary region and/or a mixing ratio of the blend of the pixel values in accordance with the position and/or width of vehicles in the periphery.
