Abstract: An image processing method includes partitioning an image under test to form a plurality of contiguous image segments having similar image properties, deriving feature data from a subset including one or more of the image segments, and comparing the feature data from the subset of image segments with feature data derived from respective image segments of one or more other images so as to detect a similarity between the image under test and the one or more other images.

Abstract: A method and a system for generating image content. The method and system allow segments of a panoramic scene, to be generated with reduced distortion. The method and system reduce the amount of distortion by mapping pixel data onto a pseudo camera focal plane which is provided substantially perpendicularly to the focal location of the camera that captured the image. A camera arrangement can implement the method and system.

Abstract: A camera movement correction apparatus for use in a system which detects the position of a sporting projectile within a scene, the apparatus comprising: an interface operable to receive a first and second image of the scene captured by a camera; a reference marker determiner operable to determine the position of a reference marker within the first and second image of the scene, the reference marker being static within the scene; a difference determination device operable to determine the difference between the position of the reference marker in the first and second image of the scene; and a corrective transformer operable to apply a corrective transform to the second image on the basis of said determined difference.

Abstract: An apparatus for detecting the position of a sporting projectile within a scene, the apparatus comprising: an interface operable to receive a plurality of images of the scene, in which the plurality of images are captured substantially simultaneously by a plurality of cameras, each camera having a different field of view of the scene; asporting projectile pattern memory module comprising data indicative of a characteristic pattern of the sporting projectile's surface; a sporting projectile pattern detection unit operable to, for each of the images, use the data from the sporting projectile pattern memory module to identify at least a part of the sporting projectile within the image and produce position and orientation data for the sporting projectile within the image; asporting projectile position detection unit operable to determine the position of the ball within the scene on the basis of the position and orientation data for the sporting projectile within each of the images and the relative positions of t

Abstract: An apparatus for determining the position of a sporting projectile within a scene during a time interval in which the sporting projectile is hidden from the view of a camera, the apparatus comprising: an interface operable to receive a first sequence of images of the scene captured by the camera at a first predetermined frame rate before the time interval and a second sequence of images of the scene captured by the camera at a second predetermined image rate after the time interval; a sporting projectile detection device operable to detect the position of the sporting projectile within the scene for each image in the first and second sequence of images; a velocity detection unit operable to determine the velocity of the sporting projectile before the time interval on the basis of the detected position of the sporting projectile within the scene for each image in the first sequence of images and the first frame rate and the velocity of the sporting projectile immediately after the time interval on the basis o
