    摘要: Described is a method and system for fast three-dimensional imaging using defocusing and feature recognition is disclosed. The method comprises acts of capturing a plurality of defocused images of an object on a sensor, identifying segments of interest in each of the plurality of images using a feature recognition algorithm, and matching the segments with three-dimensional coordinates according to the positions of the images of the segments on the sensor to produce a three-dimensional position of each segment of interest. The disclosed imaging method is “aware” in that it uses a priori knowledge of a small number of object features to reduce computation time as compared with “dumb” methods known in the art which exhaustively calculate positions of a large number of marker points.

    摘要: A system and method for improving resolution of a 3-D image by pattern inversion is disclosed. An image of a marker pattern transmitted from the surface of a 3-D object is captured with a sensor and analyzed using a 3-D image analysis method. The respective light and dark areas in the image are then inverted. The inverted image is then analyzed using a 3-D image analysis method, whereby the inversion allows for analysis of a greater portion of the image, resulting in a higher resolution 3-D image than without inversion.

    摘要: Traumatic brain injury (TBI) in a patient is assessed. A TBI diagnosis for the patient is determined based on features from MRI data, such as anatomical features, functional features, diffusion features, connectivity features from functional MRI, connectivity features from diffusion MRI, and/or network features from the connectivity features. The TBI diagnosis is determined using a trained classifier. The classifier synthesizes the features into a single number (e.g., a confidence in the prediction of the diagnosis) and indicates the features most responsible for the diagnosis. The disease trajectory for a given patient may be predicted using the trained classifier.
