摘要： A versioning system determines an amount by which a first collection and a second collection of data objects overlap. The system divides the first collection of data objects into m possibly overlapping groups of average size s and computes one combined hash result for each group. The system then constructs a first sketch vector with n elements based on the combined hash results. A respective element of the first sketch vector is selected, using a selection function, from the combined hash results that are computed with the hash function corresponding to the element's index. Next, the system receives a second sketch vector for the second collection of data objects, and determines a sketch-vector overlap between the first and second sketch vectors. The system then computes a data-object overlap between the first and second collections of data objects based on the sketch-vector overlap.

摘要： A method for matching an original document image with a copy image is disclosed. The original document image is defined as an ensemble of blocks, each of the blocks having neighboring blocks. A mask is formed for each of the blocks by dilating foreground pixels included in the block. A best match is searched in the copy image, for each of the blocks, using a search window, by correlating pixels in the mask with pixels in a corresponding portion in the copy image. Each of the best matches has a matching score. Each of the blocks is indicated as “unmatched” when the corresponding matching score is less than a matching threshold. A displacement vector is computed for each of the matched blocks.

摘要： Systems and methods are provided for automatically determining the font of text in a captured document image. Sequences of turns (left, right, straight) around the boundaries of connected components of black pixels in the captured document image are determined. The probabilities of the sequences of turns have come from a particular font within a library of known fonts can be determined using training set statistics. Using these probabilities, the most probable source font is selected.

摘要： The disclosed technology relates to the analysis of dissociation spectrum data that includes spectral peaks that represent fragments of a parent ion. The parent ion includes molecular subunits that are connected at cleavage sites. The technology accesses the dissociation spectrum data and determines a reference mass of one of the fragments where at least one of the molecular subunits in the fragment is unknown. The technology also selects a candidate parent ion description from a database of molecule descriptions where a computed ion mass of the candidate parent ion description matches the reference mass and scores the candidate parent ion description.

摘要： Systems and methods for verifying a document. A document having an encoded document data portion that includes assist information and at least one digitally-signed appended one-way hash is inputted. The encoded document data file is decoded and a representation is recovered using the assist information. A verification one-way hash is generated from the recovered representation. The verification one-way hash is then compared to the appended one way hash and the authenticity of the document is verified based on the results of the comparison.

摘要： Connected components of dark pixels are clustered from across the image. A “most likely” representative image for each cluster of images is determined, with likelihood determined by a probabilistic model of the image capturing process. An a priori (prior) probability distributions on bitmaps may be used to determine the most likely representative images. For example, a priori probability distributions based on so-called chain codes are implemented. The representative images are used to cluster connected components. Clustering may be repeated. The output page is assembled by replacing each member of a cluster of images by that cluster's representative image.

摘要： Traffic monitors based on non-imaging radiation detectors are described. A traffic monitor includes a non-imaging radiation detector that senses spatially patterned radiation emanating from objects moving in a traffic pattern. The detector generates a time varying output signal based on the sensed radiation. Signal processing circuitry is used to analyze the time varying output signal using time domain analysis to provide the traffic information.

摘要： A filter arrangement can transmit and/or reflect light emanating from a moving object so that the emanating light has time variation, and the time variation can include information about the object, such as its type. For example, emanating light from segments of a path can be transmitted/reflected through positions of a filter assembly, and the transmission functions of the positions can be sufficiently different that time variation occurs in the emanating light between segments. Or emanating light from a segment can be transmitted/reflected through a filter component in which simpler transmission functions are superimposed, so that time variation occurs in the emanating light in accordance with superposition of two simpler non-uniform transmission functions. Many filter arrangements could be used, e.g. the filter component could include the filter assembly, which can have one of the simpler non-uniform transmission functions. Time-varying waveforms from sensing results can be compared to obtain spectral differences.
