Publication number: 20150117594Abstract: Multi-energy imaging is afforded with a single detector array by generating a first data set, indicative of a first radiation energy spectrum, using a first set of cells of the array, and by generating a second data set, indicative of a second radiation energy spectrum, using a second set of cells of the array (e.g., where substantially more cells are in the first set than the second). The first data set is comprised of measured data from the first set of cells and estimated data that would have been yielded from the second set of cells had the second set been configured to detect the first energy spectrum. The second data set is comprised of measured data yielded from the second set of cells and estimated data that would have been yielded from the first set of cells had the first set been configured to detect the second energy spectrum.Type: ApplicationFiled: June 29, 2012Publication date: April 30, 2015Inventors: Julia Pavlovich, Ram Naidu

Patent number: 9002113Abstract: Processing and analyzing hyper-spectral image data and information via dynamic database updating. (a) processing/analyzing representations of objects within a sub set of the hyper spectral image data and information, using a first reference database of hyper spectral image data, information, and parameters, and, a second reference database of biological, chemical, or/and physical data, information, and parameters. Identifying objects of non-interest, and objects of potential interest, from the data/information sub-set. (b) processing/analyzing identified objects of potential interest, by further using first and second reference databases. Determining absence or presence of objects of interest, additional objects of non-interest, and non-classifiable objects of potential interest, from the data/information sub set. (c) updating first and second reference databases, using results of (a) and (b), for forming updated first and second reference databases.Type: GrantFiled: March 1, 2007Date of Patent: April 7, 2015Assignee: Green Vision Systems Ltd.Inventor: Danny S.

Publication number: 20150086117Abstract: Hyperspectral detector systems and methods for spectrally analyzing a scene are disclosed. The methods include capturing a context image and a single-column spectral image that falls within the context image. The spectral image is panned over the scene and within the context image to capture spectral signatures within the scene. The spectral signatures are compared to reference spectral signatures, and the locations of the one or more spectral signatures are marked. The systems and methods obviate the need to store and process large amounts of spectral data and allow for real-time display of the fused context image and spectral image, along with the marked locations of matched spectral signatures.Type: ApplicationFiled: August 27, 2014Publication date: March 26, 2015Inventors: Lovell Elgin Comstock II, Leon J. Desmarais, Jeffry John Santman, Peter Gerard Wigley, Patrick W. Woodman

Patent number: 8977023Abstract: Methods, systems and computer program products for managing frequency domain optical coherence tomography (FDOCT) image resolution. A spectrum used to acquire an image of a subject is calibrated and default dispersion correction parameters are set. Default dispersion management parameters associated with a region of the image of the subject are also set. The image of the subject is acquires after setting the default dispersion correction parameters and the default dispersion management parameters. A quality of the acquired image is compared to a quality metric for the acquired image. The dispersion correction parameters are adjusted if the quality of the acquired image does not meet or exceed the quality metric for the acquired image. The acquired image is reprocesses based on the adjusted dispersion correction parameters. The steps of comparing, adjusting and reprocessing are repeated until the acquired image meets or exceeds the quality metric for the acquired image.Type: GrantFiled: January 23, 2014Date of Patent: March 10, 2015Assignee: Bioptigen, Inc.Inventor: Eric L. Buckland

Patent number: 8976231Abstract: A device for measuring three dimensional shape includes a first irradiation unit, a first grating control unit, a second irradiation unit, a second grating control unit, an imaging unit, and an image processing unit. After performance of a first imaging operation as imaging processing of a single operation among a multiplicity of imaging operations performed by irradiation of said first light pattern of multiply varied phases, a second imaging operation is performed as imaging processing of a single operation among a multiplicity of imaging operations performed by irradiation of said second light pattern of multiply varied phases. After completion of the first imaging operation and the second imaging operation, shifting or switching operation of the first grating and the second grating is performed simultaneously.Type: GrantFiled: July 30, 2012Date of Patent: March 10, 2015Assignee: CKD CorporationInventor: Hiroyuki Ishigaki

Patent number: 8897571Abstract: Provided is a process and system for detection of sparse or otherwise weak targets in a hyperspectral image. A hyperspectral image is received having a multitude of pixels, with each pixel having a respective spectrum. In some embodiments, multiple mean spectra are selectively determined for respective sub-regions of the hyperspectral image. The subset mean spectra can be selectively removed from respective pixels, thereby improving image fidelity due to sensor artifacts. Additionally, target detection of such an adjusted image can be determined by one or more of matched filter techniques or by partial un-mixing. In at least some embodiments target detection is enhanced by combining a measure of target match with a residual spectrum determined as a measure of un-match. Target detection can be further improved by application of rules, for example, related to target detection threshold.Type: GrantFiled: March 31, 2011Date of Patent: November 25, 2014Assignee: Raytheon CompanyInventors: Ian S.
