摘要： Magnetic source imaging (MSI) involves the reconstruction of the current sources in a portion of a body, such as an organ, from measured magnetic field data. The measured magnetic field data may be from one-dimensional or three-dimensional sensors. Aspects of the present invention include systems and methods for reconstructing the electrical current of an organ given magnetic data. In embodiments, reconstruction of three-dimensional current sources is accomplished knowing or estimating the position, or offset, of the sensor plane with respect to the patient in order to form a set of linear equations. Alternatively, reconstruction of three-dimensional current sources is accomplished without knowing the offset of the sensor plane with respect to the patient. In embodiments, the linear and nonlinear systems of equations are iteratively used to obtain the current source information. In embodiments, multi-scale strategies are employed.

摘要： An image created by a first projector is recreated using a second projector by relating the two projectors to a common point of view, preferably as viewed from a camera. A first transport matrix T1 is captured to relate the first projector to the camera. A second transport matrix T2 is then capture to relate the second projector to the camera. To have a first image p1, as projected by the first projector, reproduced by the second projector, the second projector projects a distorted image defined as (T2−1)(T1)p1. The inverse of T2, as used in this equation is an estimation defined by first creating an intermediate matrix {hacek over (T)} of equal size as T2. If a column in T2 is denoted as Tr and a corresponding column in {hacek over (T)} is denoted as {hacek over (T)}r, then the construction and population of {hacek over (T)} is defined as {hacek over (T)}r=Tr/(∥Tr∥)2, and the inverse of T2 is estimated as the transpose of {hacek over (T)}.

摘要： Aspects of the present invention include systems and methods for obtaining a light transport between a projector and a camera. In embodiments, the light transport between the projector and the camera is represented as a matrix and is obtained assuming that the projector displays on a surface that is planar or at least substantially planar. The light transport matrix is obtained by finding a homography between the projector and the camera. Using the homography to correlate camera and projector pixels and using color values in a captured solid color image, the light transport matrix can be obtained. In embodiments, at least an approximation of an inverse light transport matrix can also be computed, which is useful for many applications, such as inferring unknown projector images.

摘要： Embodiments of the present invention enable compression and decompression of data. Applications of the present invention are its use in embodiments of systems for compression and decompression of GPS long-term Ephemeris (LTE) data, although the present invention is not limited to such applications. In embodiments, the LTE data may be grouped into a set of data values associated with a parameter. In embodiments, a data set may be compressed by using a multi-order differencing scheme. In such a scheme, a set of the differences between values may be compressed because the differences have smaller magnitudes than the values. In embodiments, a multi-order differencing scheme determines how many levels (orders) of differencing may be applied to an original data set before it is compressed. In embodiments, the original data may be recovered from a compressed data set based on the type of multi-order differencing scheme used to generate the compressed data.

摘要： Disclosed are embodiments of systems and methods to stitch two or more images together into a composite image. By finding matching point pairs for a pair of images, a homography transform may be obtained for the pair of images. The homography transform may be used to generate a composite image of the image pair. In an embodiment, the process of identifying a homography transform may be iterated. In an embodiment, when forming the composite image, the transformed foreground regions may be selected such that there is no intersection of foreground pixel regions. In an embodiment, foreground pixel regions on the border of an image may be removed. The resulting composite image is a larger image generated from the selected regions from the input images. In embodiments, the process may be repeated for sets of images with more than two images.

摘要： Systems and methods for developing and using adaptive threshold values for different input images for object detection are disclosed. In embodiments, detector response histogram-based systems and methods train models for predicting optimal threshold values for different images. In embodiments, when training the model, an optimal threshold value for an image is defined as the value that maximizes the reduction of false positive image patches while preserving as many true positive image patches as possible. Once trained, the model may be used to set different threshold values for different images by inputting a detector response histogram for the image patches of an image into the model to determine a threshold value for detection.
