摘要： A method captures a video image frame of a book, estimates a position of at least a first endpoint of the book's spine, applies an edge detection operation to the video image frame to generate an edge image, applies a Hough transform to a first region in the edge image to obtain a plurality of line estimates, and rejects line estimates that do not substantially intersect with an estimated endpoint of the book's spine. For line estimates that are not rejected, detecting one or more clusters of angles of the line estimates with respect to an estimated endpoint of the book's spine, and generating an average angle from the cluster of angles. An average angle is selected, and an angular position of the turning leaf in the book's image responsive to the currently selected average angle is estimated.

摘要： A method of rendering an image based upon a first stereoscopic image comprising a pair of images is provided. The method includes generating a virtual three-dimensional model of the scene depicted in the first stereoscopic image responsive to distances derived from the first stereoscopic image, detecting one or more free edges in the three dimensional model, and generating one or more textures for the virtual three-dimensional model from at least one of the pair of images of the first stereoscopic image. The method also includes applying at least one texture to a respective part of the three dimensional model, and rendering the virtual three dimensional model from a different viewpoint to that of the first stereoscopic image. Rendering the virtual three dimensional model comprises modifying a transparency of rendered pixels of an applied texture as a function of the pixel's distance from that free edge.

摘要： A method of image reconstruction is provided. The method includes capturing a stereoscopic pair of images of a scene, generating a disparity map for the pair of images, and defining a series of value ranges corresponding to disparity with each value range in the series having an end point corresponding to a greater disparity than an end point of preceding value ranges in the series. For each value range in the series, and progressing in order through the series from the first value range in the series, the method includes selecting points in the disparity map falling within the respective value range and generating a mesh responsive to those selected points. The method also includes subsequently merging the series of generated meshes to form a 3D model of the scene.

摘要： An imaging system includes a video camera having a wide field of view lens, an imaging sensor operable to form a first image having a first pixel area, and an interface operable to receive commands from a host entertainment device. The video camera is operable to receive a command requesting at least one secondary image having a second pixel area for a 3D mapping of a portion of the first image. The system includes a graphics processor operable to perform the 3D mapping to generate the at least one each secondary image from the first image. The 3D mapping transforms a section of the first image depicting a surface having a normal in a first direction to form a secondary image in which the normal of that surface faces directly out of the secondary image.
