  • Patent number: 10524733
    Abstract: A method for improving the signal to noise ratio of an EEG signal in which a wavelet packet decomposition having a plurality of levels is first applied to a time slice of the EEG signal. A default signal is set to the first wavelet packet and a default peak response is then calculated for the first wavelet node. An update signal is set to the default signal combined with another of the wavelet nodes and an update peak response signal is then calculated of the update signal. If the update peak response signal exceeds the default peak response, the default peak response is set equal to the update peak response and the default signal is set equal to the update signal. Otherwise, the value of the current node is set to zero which effectively eliminates the signal data of the current wavelet node. These steps are reiterated for all of the wavelet nodes and, thereafter, a composite waveform of the EEG signal is reconstructed from the non-zero wavelet nodes.

  • Patent number: 9959587
    Abstract: Signal processing devices and methods estimate a geometric transform of an image signal. From a seed set of transform candidates, a method applies a seed transform candidate to a reference signal. For each candidate, update coordinates of reference signal features are identified in the image signal and provided as input to a least squares method to compute an update to the transform candidate. At the end of the process, the method identifies a geometric transform or set of top transforms based on a further analysis of correlation, as well as other results. Phase characteristics are exploited in the process of updating coordinates. The geometric transform is used to facilitate extracting embedded digital messages from the image.

  • Patent number: 8639038
    Abstract: The disclosure concerns hyperspectral and multispectral image. The disclosure concerns the computation of a descriptor for such an image. The descriptor can be used in a range of image post-processing applications, such as classification, recognition, tracking and localization. Aspects of the invention include a computer implemented method and a computer system. To computer the descriptor for a set of wavelength indexed bands, a band representation of the radiance measurements for that band based on a probability distribution function is computed 300. Then a wavelength-dependent cross-correlation between the band representations is computed 302. Finally, a descriptor based on the computed cross-correlation between the band representations is computed 304. It is an advantage that the descriptor captures a discriminative and descriptive representation of scene captured in the hyperspectral or multispectral image.

  • Patent number: 8055077
    Abstract: A realtime display compression for a waveform image uses a priority basis for combining groups of pixels when producing a compressed waveform image in order to preserve intensity information. As an example successive lines of data for the waveform image are demultiplexed into line buffers in a circulating manner, the number of line buffers being a function of the maximum desired integer compression ratio. The outputs from the line buffers are aligned and the corresponding pixels are combined according to a desired compression ratio, one output line for each integer compression ratio. The appropriate compressed line is selected as the output line according to the desired compression ratio, with the totality of the output lines forming the compressed waveform image.

  • Patent number: 8023718
    Abstract: A method for linking front and rear images in a document processing system involves linking the front and rear images by a magnetic ink character code line. The document processing system includes an imaging device and a magnetic ink character recognition (MICR) reader. The method comprises capturing a first image and first MICR waveform for the front side of the document, and capturing a second image and second MICR waveform for the rear side of the document. A forward recognition algorithm is applied to the first waveform to produce a first code line. A reverse recognition algorithm is applied to the second waveform to produce a second code line. The reverse recognition algorithm considers the second waveform as resulting from the document being read from the rear side of the document when processing the second waveform.

  • Patent number: 8023717
    Abstract: A method for processing backwards documents in a document processing system involves a reverse recognition algorithm. The document processing system includes a magnetic ink character recognition (MICR) reader. A waveform is determined for a magnetic ink character string on a document. A forward recognition algorithm is applied to compare the determined waveform to a set of known character profiles. In a case where the magnetic ink character string remains unrecognized after application of the forward recognition algorithm, a reverse recognition algorithm is applied to compare the determined waveform to the set of known character profiles. The reverse recognition algorithm considers the determined waveform as resulting from the document being oriented backwards when passing though the magnetic ink character recognition reader when comparing the waveform to the set of known character profiles.

  • Patent number: 8014609
    Abstract: A system allows greater dynamic range in fixed-width sample representations of waveforms. Known properties of the waveform are used to determine an unlikely, or impossible, data condition to be used as an exception condition. In a preferred embodiment that is directed to processing of audio waveforms, a first large value transitioning to a second large value of different sign is used to indicate an exception condition. Samples following the exception condition are assumed to be shifted by a predetermined amount so that their representation within the allowable dynamic range of the word results in an extended dynamic range. In a preferred embodiment, pre-processing of a waveform is used to create exception conditions and to perform “peak packing” to shift portions of the waveform that would otherwise become clipped, so that the waveform peaks reside in a shifted position within the digital representation.

  • Patent number: 7986321
    Abstract: A system and method for illuminating an object in preparation for three-dimensional rendering includes a projection device configured to project at least three two-dimensional structured light patterns onto a 3-dimensional object. At least two cameras detect light reflected by the object in response to the at least three structured light patterns. Each structured light pattern varies in intensity in a first dimension and is constant in a second dimension. A single line along the first dimension of a given structured light pattern is created from a superposition of three or more component triangular waveforms. Each component triangular waveform has an amplitude, a periodicity (frequency), and a phase shift which is implemented as a pixel shift. Each component triangular waveform may be subject to one or more waveshaping operations prior to being summed with the remaining component triangular waveforms. The summed waveform itself may also be subject to waveshaping operations.

  • Patent number: 7970212
    Abstract: The invention is a method of using Wavelet Transformation and Artificial Neural Network (ANN) systems for automatic detecting and classifying objects. To train the system in object recognition different images, which usually contain desired objects alongside other objects are used. These objects may appear at different angles. Different characteristics regarding the objects are extracted from the images and stored in a data bank. The system then determines the extent to which each inserted characteristic will be useful in future recognition and determines its relative weight. After the initial insertion of data, the operator tests the system with a set of new images, some of which contain the class objects and some of which contain similar and/or dissimilar objects of different classification.

  • Patent number: 7920743
    Abstract: A method of displaying a time sequence of 2-dimensional data represents each data set in the time sequence as a normalized figure based upon a reference set of data. The perimeter of the normalized figure is color coded to represent deviations from a data standard that corresponds to the 2-dimensional data. For subsequent data sets in the time sequence each normalized figure is sized to form a series of concentric figures for display representing all the data sets in the time sequence so that patterns of both rotational and magnitude changes are visually apparent.

  • Patent number: 7870574
    Abstract: A method and system for the automatic identification of audio, video, multimedia, and/or data recordings based on immutable characteristics of these works. The invention does not require the insertion of identifying codes or signals into the recording. This allows the system to be used to identify existing recordings that have not been through a coding process at the time that they were generated. Instead, each work to be recognized is “played” into the system where it is subjected to an automatic signal analysis process that locates salient features and computes a statistical representation of these properties. These features are then stored as patterns for later recognition of live input signal streams. A different set of features is derived for each audio or video work to be identified and stored. During real-time monitoring of a signal stream, a similar automatic signal analysis process is carried out, and many features are computed for comparison with the patterns stored in a large feature database.
