Abstract: Implementations provide method that includes: accessing data encoding the one or more images sized and shaped for presentation on a square or rectangular surface; providing the first set of data for warping by one or more computer processors such that each of the one or more images is projected onto a respective trapezoidal surface having a first base and a second base that is longer than the first base, wherein the first base is arranged to be closer to a viewer than the second base, and wherein a first portion of each image is projected further away from the viewer than a second portion of each image; and presenting each of the projected one or more images on the respective trapezoidal surface, wherein the first portion of each projected image is presented by the first base and the second portion of each projected image is presented by the second base.

Abstract: A vector based mosaic design system has a graphical processing module, a display module, a plugin application module and memory, and it operates to receive an original input image and mosaic design information from an artist. The plugin module has logical instructions that operate on the information received from the artist to determine the position of curves that are offset from a mosaic design region boundary or feature curve, and the plugin also operates to determine the positions and dimensions of tiles in courses that are defined by the positions of feature curves and curves that are offset from them.

Abstract: A page turner apparatus includes a book holder assembly, one or more page turning assemblies and a driver. Each page turning assembly includes a rotator portion and a page retention portion and is laterally movable and rotatable. The page retention portion includes a page retaining arm which is rotated to the right of an axis of rotation when the page turning assembly is moved to the right and rotated to the left of the axis of rotation when the page turning assembly is moved to the left. The driver is adapted to laterally move the at least one page turning assembly and, at the same time, rotate each page retaining arm.

Abstract: A system and related method for automatically aligning a plurality of 2D images of a scene to a first 3D model of the scene. The method includes providing a plurality of 2D images of the scene, generating a second 3D model of the scene based on the plurality of 2D images, generating a transformation between the second 3D model and the first 3D model based on a comparison of at least one of the plurality of 2D images to the first 3D model, and using the transformation to automatically align the plurality of 2D images to the first 3D model.

Abstract: An efficient way to perform rendering operations in an image processing environment includes a warping engine having a warping module and a domain of definition (DOD) module. When an object is warped, a new DOD for the image is determined by the warping engine by comparing the location of certain pixels in the warped image with their corresponding locations in the original image. By maintaining a DOD for the warped images, only that portion of the DOD that intersects with a region of interest is computed, thus resulting in optimized performance.

Abstract: An improved automatic page turner for turning selected bound pages, in which the automatic page turner has a frame and one or more pickup arms rotatably coupled to the frame which are capable of intermittently exerting a pressure against the selected bound pages, wherein a page ledge is connected to the frame suitable for separating the selected bound pages from remaining bound pages, together with means for biasing the remaining bound pages against the page ledge, such as one or more helical springs.

Abstract: An apparatus for turning bound pages, the apparatus having a support assembly for holding the bound pages; a lifting assembly coupled to the support assembly and capable of lifting at least a portion of a page; a turnstile assembly, the turnstile assembly comprising a plurality of flippers; and a motor assembly secured to the support assembly and coupled to the turnstile assembly; wherein the turnstile assembly has a rest position in which one of the plurality of flippers is positioned across two opposed bound pages to hold the bound pages in an open condition; wherein the turnstile assembly is rotated by the motor assembly causing the lifting assembly to lift one of the pages and one of the plurality of flippers to rotate underneath the lifted page; and wherein the finger underneath the lifted page is rotated to turn the page and to place the turnstile in the rest position.

Abstract: An apparatus for turning bound pages, the apparatus having a frame; a book support assembly coupled to the frame; at least one pickup arm coupled to the frame; a motor assembly coupled to the frame; and a conveyor assembly coupled to the frame. The conveyor assembly has a belt; a plurality of fingers coupled to the belt; and at least one actuator coupled to the belt. A subset of the plurality of fingers hold the book in an open condition. Upon rotation of the belt by the motor assembly, the at least one actuator causes the at least one pickup arm to lift a portion of a page while a subset of the plurality of fingers hold the bound pages in an open condition and turn the lifted page.

Abstract: The present invention is a method and apparatus for restoring or correcting digital images scanned in the presence of mechanical vibration, thereby improving the quality of the output image. In a document scanner, a linear sensor moving relative to a document placed upon a platen is scanned in a manner wherein fluctuations in the nominal scanning velocity are observed. Recognizing that the output of a single photosensor in the linear sensor array is proportional to the integrated irradiance received by the sensor as it scans through an exposure region, when vibratory motion of the sensor array is considered, the actual size of the exposure region is time-varying. The fluctuations or vibrations introduce artifacts such as brightness fluctuation and geometric warping which are eliminated or significantly reduced in accordance with the method of the present invention.

Abstract: A two-dimensional image is subjected to a three-dimensional effect, such as folding, twisting or rotation, and transformed or warped into a modified output image. By successive one-dimensional resampling along two coordinates and parallel channel processing of transposed input image data with rejection of distorted pixel value data, bottleneck, shear and other distortions are addressed. Complete warping systems, resampling subsystems and related methods are disclosed.
