摘要： A method and apparatus for high-resolution 3D imaging ladar system which can penetrate foliage and camouflage to sample fragments of concealed surfaces of interest is disclosed. Samples collected while the ladar moves can be integrated into a coherent object shape. In one embodiment, a system and method for automatic data-driven registration of ladar frames, comprises a coarse search stage, a pairwise fine registration stage using an iterated closest points algorithm, and a multi-view registration strategy. After alignment and aggregation, it is often difficult for human observers to find, assess and recognize objects from a point cloud display. Basic display manipulations, surface fitting techniques, and clutter suppression to enhance visual exploitation of 3D imaging ladar data may be utilized.

摘要： A system and method for accurately mapping between camera coordinates and geo-coordinates, called geo-spatial registration, using a Euclidean model. The system utilizes the imagery and terrain information contained in the geo-spatial database to precisely align geographically calibrated reference imagery with an input image, e.g., dynamically generated video images, and thus achieve a high accuracy identification of locations within the scene. When a sensor, such as a video camera, images a scene contained in the geo-spatial database, the system recalls a reference image pertaining to the imaged scene. This reference image is aligned very accurately with the sensor's images using a parametric transformation produced by a Euclidean model. Thereafter, other information that is associated with the reference image can easily be overlaid upon or otherwise associated with the sensor imagery.

摘要： A method and apparatus that determines the topology of a sequence of images and then globally aligns the images with respect to each image's neighboring images. The apparatus includes a topology determination module, a local coarse registration module, a local fine registration module, a global consistency module, and a color matching/blending module. To accurately render a mosaic image from a sequence of images the topology determination and global alignment processes are iterated to progressively produce accurately aligned images. The apparatus efficiently and accurately combines a plurality of source images into a seamless panoramic mosaic representation of a scene, of arbitrarily wide spatial and angular extent, regardless of the order of image acquisition.

摘要： An exemplary method for simplifying a texture of a three-dimensional model includes simplifying a first three-dimensional model to determine a second three-dimensional model. The first three-dimensional model has a higher resolution than the second three-dimensional model. The method also includes allocating a texture atlas for the second three-dimensional model. The method further includes filling in the texture atlas for the second three-dimensional model. Filling in the texture atlas may include determining a location on the second three-dimensional model corresponding to a pixel in the texture atlas for the second three-dimensional model, determining a location on the first three-dimensional model corresponding to the determined location on the second three-dimensional model, determining a color value texture mapped to the first three-dimensional model at the determined location on the first three-dimensional model, and setting the determined color value to the pixel in the texture atlas for the second three-dimensional model.

摘要： Method and apparatus for processing a sequence of images to detect object movement within the sequence. Specifically, the method comprises the steps of: (a) supplying a sequence of image frames; (b) initializing a reference image that contains image information regarding stationary objects within a scene represented by the sequence of images; (c) supplying a next image frame which temporally follows the sequence of image frames; (d) comparing the next image to the reference image to produce a motion image representing motion information regarding movement of objects within the scene; (e) updating the reference image with information within the next image that represents stationary objects within the scene; and (f) repeating steps (c), (d), and (e) for each next image supplied. The method is implemented by image processing apparatus. A specific embodiment of the method and apparatus is a traffic monitoring system that identifies vehicles in varying illumination levels and eliminates erroneous identification of non-physical movement in the scene such as shadows and headlight reflections.

摘要： Iris recognition is achieved by (1) iris acquisition that permits a user to self-position his or her eye into an imager's field of view without the need for any physical contact, (2) spatially locating the data defining that portion of a digitized video image of the user's eye that defines solely the iris thereof without any initial spatial condition of the iris being provided, and (3) pattern matching the spatially located data defining the iris of the user's eye with stored data defining a model iris by employing normalized spatial correlation for first comparing, at each of a plurality of spatial scales, each of distinctive spatial characteristics of the respective irises that are spatially registered with one another to quantitatively determine, at each of the plurality of spatial scales, a goodness value of match at that spatial scale, and then judging whether or not the pattern which manifests solely the iris of the user's eye matches the digital data which manifests solely the model iris in accordance with a certain combination of the quantitatively-determined goodness values of match at each of said plurality of spatial scales.
