Patent number: 8526754Abstract: An electronic device may have a digital image sensor for capturing an image and may have storage and processing circuitry for processing the image to produce a corresponding enhanced depth-of-field image. Multiple image areas, within a given image may be processed. As each image area is processed, a signal-to-noise ratio may be computed. A kernel parameter characteristic curve may be used to select values to be used for kernel parameters for each image area based on the computed signal-to-noise ratio for that image area. Kernels may be generated for each image area and the generated kernels may be convolved with their respective image areas to modify the image areas. This allows each image area to be selectively sharpened or smoothed based on its signal-to-noise ratio. Image areas with low and high signal-to-noise ratios may be sharpened less those with moderate signal-to-noise ratios to enhance depth of field in the image.Type: GrantFiled: May 28, 2009Date of Patent: September 3, 2013Assignee: Aptina Imaging CorporationInventors: Brian Keelan, Dan Lelescu

Publication number: 20130208950Abstract: An analysis system automatically analyzes and counts fluorescence signals present in biopsy tissue marked using Fluorescence in situ Hybridization (FISH). The user of the system specifies classes of a class network and process steps of a process hierarchy. Then pixel values in image slices of biopsy tissue are acquired in three dimensions. A computer-implemented network structure is generated by linking pixel values to objects of a data network according to the class network and process hierarchy. Objects associated with pixel values at different depths of the biopsy tissue are used to determine the number, volume and distance between cell components. In one application, fluorescence signals that mark Her2/neural genes and centromeres of chromosome seventeen are counted to diagnose breast cancer. Her2/neural genes that overlap one another or that are covered by centromeres can be accurately counted. Signal artifacts that do not mark genes can be identified by their excessive volume.Type: ApplicationFiled: February 26, 2013Publication date: August 15, 2013Applicant: Definiens AGInventor: Definiens AG

Patent number: 8331723Abstract: Signal processing techniques are applied to digital image data to remove the distortion caused by motion of the camera, or the movement of the subject being photographed, or defective optics, or optical distortion from other sources. When the image is captured, the effect of relative motion between the camera and the subject is that it transforms the true image into a blurred image according to a 2-dimensional transfer function. The 2-dimensional transfer function representing the motion is derived using blind estimation techniques or by using information from sensors that detect the motion. The transfer function is inverted and used to define a corrective filter. The filter is applied to the image and the blur due to the motion is removed, restoring the correct image. Another embodiment uses the transfer function to avoid blur by combining multiple consecutive images taken at a fast shutter speed.Type: GrantFiled: March 24, 2005Date of Patent: December 11, 2012Inventor: Fatih M.

Patent number: 8233747Abstract: A method and apparatus for generating a super-resolution image are provided. The method may include obtaining a first set of RAW data representing a first image captured at a first resolution and obtaining, from the first set of RAW data, at least one first sample of data associated with the first image. The method may also include obtaining a second set of RAW data representing a second image captured at the first resolution, and performing image registration as a function of the first set of RAW data and the second set of RAW data so as to obtain at least one second sample of data associated with the second image. The first set of RAW data is used as a reference for the second set of RAW data. The method further includes combining the at least one first sample of data with at least one second sample of data to form a collection of samples, and interpolating the collection of samples to form the super-resolution image.Type: GrantFiled: April 3, 2009Date of Patent: July 31, 2012Assignees: Sony Corporation, Sony Electronics, Inc.Inventors: Gazi Ali, Ming-Chang Liu

Patent number: 8222040Abstract: Nucleic acid microparticles are sequenced by performing a sequencing reaction on the microparticles using one or more reagents, selectively exciting the microparticles in an excitation pattern, optically imaging the microparticles at a resolution insufficient to resolve individual microparticles, and processing the optical images of the microparticles using information on the excitation pattern to determine the presence or absence of the optical signature, which indicates the sequence information of the nucleic acid. An apparatus for optical excitation of the microparticles comprises an optical fiber delivering a first laser beam, and an interference pattern generation module coupled to the optical fiber. The interference pattern generation module splits the first laser beam into second and third laser beams and generates the excitation pattern for selectively exciting the microparticles by interference between the second and third laser beams.Type: GrantFiled: August 28, 2007Date of Patent: July 17, 2012Assignee: LightSpeed Genomics, Inc.Inventors: Stanley S.

Patent number: 8204287Abstract: A hemorrhage edge candidate area extraction section extracts a candidate area for the outline part of a hemorrhage area, based on an image signal of a medical image constituted by multiple color signals obtained by capturing an image of a living body. A feature quantity calculation section calculates a feature quantity of the hemorrhage area based on calculation of the amount of change in the image signal in a small area including the candidate area, among multiple small areas obtained by dividing the medical image. A hemorrhage edge determination section determines whether or not the candidate areas are the outline part of the hemorrhage area based on the feature quantity.Type: GrantFiled: August 19, 2010Date of Patent: June 19, 2012Assignee: Olympus Medical Systems Corp.Inventors: Ryoko Inoue, Tetsuo Nonami

Patent number: 8204288Abstract: There is provided a method of processing an ultrasound spectrum image. According to such method, a spectrum image is formed based on ultrasound data and then the noise is removed from the spectrum image. The noise-removed spectrum image is matched with one or more spectrum models representing specific spectrum types. Then, whether or not the noise-removed spectrum image contains an aliasing is checked. If the noise-removed spectrum image contains the aliasing, then the aliasing is removed from the noise-removed spectrum image to provide a noise-removed spectrum image without the aliasing. Thereafter, contour tracing is performed on the noise-removed spectrum image without the aliasing to detect contour points. Further, peak tracing is performed on the noise-removed spectrum image without the aliasing to detect peaks.Type: GrantFiled: November 17, 2010Date of Patent: June 19, 2012Assignee: Medison Co., Ltd.Inventors: Hye Jung Kim, Ki Jong Lee, Sung Ho Kim, Eun Ho Yang, Cheol An Kim

Patent number: 8189931Abstract: A method and system are disclosed for matching input character sequences in a set of input patterns. The method comprises the steps of analyzing the set of input patterns, creating a pattern cluster look-up table (PCLT) based on said input patterns, and defining an offset value k. The PCLT is used to find, for each sequence s and offset k, a set of candidate patterns that can possibly match s, the set of candidate patterns is searched for patterns that match s, and all found matching patterns and sequences are reported.Type: GrantFiled: January 4, 2008Date of Patent: May 29, 2012Assignee: International Business Machines CorporationInventors: Tien Huynh, Stanislav Polonsky, Isidore Rigoutsos

Patent number: 8170308Abstract: A method for use in functional medical imaging includes adaptively partitioning functional imaging data as a function of a spatially varying error model. The functional image data is partitioned according to an optimization strategy. The data may be visualized or used to plan a course of treatment. In one implementation, the image data is partitioned so as to vary its spatial resolution. In another, the number of clusters is varied based on the error model.Type: GrantFiled: May 1, 2007Date of Patent: May 1, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Alexander Fischer, Lothar Spies, Carsten Meyer
