    摘要: A method for tone mapping a high dynamic range image of a large terrestrial area into a lower dynamic range image uses a globally aware, locally adaptive approach whereby local tonal balancing parameter values are derived from known tone mapping parameters for a local 3×3 matrix of image tiles and used in turn to derive a local sigmoid transfer function for pixels in the tile in the middle of the matrix. A global sigmoid transfer function is derived based on values of the tone mapping parameters applicable to the entire image. A lower dynamic range image pixel will have a local tone mapped value and a globally tone mapped value, which are combined by giving each a weighted value to provide a final low dynamitic range pixel value.

    摘要: An expanded field of view visual display concept capable of conducting credible close-in or within visual range (WVR) air-to-air combat from a single computer graphics display screen. By use of the invention, the visual scene content that normally exists outside and around the cockpit of a fighter aircraft can be condensed onto a single CRT screen or video projection screen in such a manner that pilots have good situational awareness, even in close-in-combat, and can fly credible air combat. An expanded field of view visual display is created, referred to as target coordinate display (TCD), capable of conducting credible close-in simulated air combat from a single CRT display or video projection screen. The display handles multiple aircraft, shows friendly aircraft formations, is usable in real time, shows weapon release information, is easily adapted to by pilots, and yields credible air combat simulation results.

    摘要: When photographs are to be combined into a single image, haze correction and/or color balancing may be performed. The photographs may be analyzed and left-clipped in order to darken the photographs and to increase the density of pixels in the low-luminosity region, thereby decreasing the perception of haze. When the photographs are combined into one continuous image, tie points are selected that lie in regions where the photographs overlap. The tie points may be selected based on visual similarity of the photographs in the region around the tie point, using a variety of algorithms. Functions are then chosen to generate saturation and luminosity values that minimize, at the tie points, the cost of using the generated values as opposed to the actual saturation and luminosity values. These functions are then used to generate saturation and luminosity values for the full image.
