    摘要: The present invention is a method for presenting the fisheye-camera images. A calibration target with a concentric-and-symmetric pattern (PCT) is utilized to assist in parameterizing a fisheye camera (FIS) in order to ascertain the optical parameters comprising the principal point, the focal length constant and the projection function of the FIS. Hence, the position of an imaged point referring to the principal point on the image plane directly reflects its corresponding zenithal distance α and azimuthal distance β of the sight ray in space so as to normalize the imaged point onto a small sphere. Further according to the map projections in cartography capable of transforming the global geometry into flap maps, the interesting area in a field of view can be accordingly transformed by a proper projection method. The image transforming method disclosed in the invention is simple, low-cost, suitable to various FISs with different projection mechanisms and capable of transforming the fisheye-camera images for particular functions, such as the approach of normal human visual perception, video data encryption, and image compression/transformation with a high fidelity.

    摘要: A method for generating a presentation of a region-of-interest in an original image for display on a display surface, the method comprising: establishing a lens for the region-of-interest, the lens having a focal region with a magnification for the region-of-interest at least partially surrounded by a shoulder region across which the magnification varies to provide a continuous transition from the focal region to regions outside the lens; receiving a first signal for selecting the shoulder region; while receiving the first signal, receiving a second signal for selecting the focal region and for adjusting a position of the focal region relative to the shoulder region to define a degree and a direction of a folding of the focal region over the shoulder region for the lens; and, applying the lens to the original image to produce the presentation.

    摘要: A method is for inverting a distorted surface presentation into an undistorted surface presentation in a detail-in-context presentation system including the steps of: selecting an input point on the undistorted surface; calculating a vector from the input point to a reference viewpoint; locating a starting point lying above the distorted surface and on the vector; locating a first bracketing point for a first intersection point of the vector and the distorted surface lying above the distorted surface and on the vector; locating a second bracketing point for the first intersection point lying below the distorted surface, and below the first intersection point, but above any subsequent intersection points of the vector and the distorted surface; locating a midpoint between the first and second bracketing points; and, determining if the midpoint is an acceptable approximation for the first intersection point thus being an inversion point corresponding to the input point.

    摘要: A method is disclosed for displaying endoscopic images that includes three-dimensional surfaces, variable viewing points, directions, and orientations. A computer receives a captured endoscopic image. A virtual surface is defined in the computer with the captured image textured onto the virtual surface. A virtual viewing point, virtual viewing direction, and virtual viewing orientation are defined relative to the virtual surface. A rendered image of the virtual surface is then created. The rendered image is displayed to the user. Video is displayed on the virtual surface by updating the image texture with each new frame.

    摘要: This invention relates to a self diagnostic apparatus for a radiographic imaging system. The system includes a radiographic source and a camera, and the apparatus comprises: a scintillator positioned between the optical pathway of the radiographic source and the camera, and made of a material which fluoresces when struck by x-rays, including one in the group of terbium doped gadollineum oxysulfide or thallium doped cesium iodide; a resolution target located at the periphery of the scintillator and made of a material that passes at least shortwave ultraviolet light; an ultraviolet source positioned in line of sight of the scintillator and target; and, a control system for capturing a self-diagnostic reference image by activating the ultraviolet source, and activating the camera to take an image created by the visible light emitted by the scintillator material when illuminated by the UV light. A short wavelength UV light for example 254 nm excites the scintillator material to emit light from which can then be captured an image of the resolution targets.

    摘要: An image editing system uses a loupe cursor to magnify a selected area of a basic image displayed on a display device. The system generates basic image data representing the selected area of the basic image, and generates magnified image data by magnifying the selected basic image data. It displays within the loupe cursor a loupe image based on the magnified image data. When a user editing signal is received for editing the loupe image, the system generates modified image data, and dynamically modifies the loupe image displayed within the loupe cursor based on the modified image data.
