  • Publication number: 20160113546
    Abstract: Methods and systems process an MRI image to detect cancer. A method includes forming a series of binary threshold intensity images from an MRI image of a patient. Each of the binary threshold intensity images is based on a respective intensity. The binary threshold intensity images are processed to identify one or more bright extremal regions in which image pixels have the same value, and for which corresponding image pixels in the MRI image have a higher intensity than surrounding image pixels in the MRI image. One or more bright maximally stable extremal regions are selected from the identified bright extremal regions based on change in area of one or more respective bright extremal regions for different binary threshold images in the series. At least one of the selected one or more bright maximally stable extremal regions may be identified as potentially cancerous.

  • Publication number: 20160117830
    Abstract: Methods and systems for detecting and/or tracking one or more objects utilize depth data. An example method of detecting one or more objects in image data includes receiving depth image data corresponding to a depth image view point relative to the one or more objects. A series of binary threshold depth images are formed from the depth image data. Each of the binary threshold depth images is based on a respective depth. One or more depth extremal regions in which image pixels have the same value are identified for each of the binary depth threshold images. One or more depth maximally stable extremal regions are selected from the identified depth extremal regions based on change in area of the one or more respective depth extremal regions for different depths.

  • Patent number: 9311555
    Abstract: Architecture for real-time extraction of maximally stable extremal regions (MSERs) is disclosed. The architecture includes a communication interface and processing circuitry that are configured in hardware to receive a data stream of an intensity image in real-time and provide labels for light image regions and dark image regions within the intensity image that match a given intensity threshold during a single processing pass. The communication interface and processing circuitry are also configured in hardware to find extremal regions within the intensity image based upon the labels and to determine MSER ellipses parameters based upon the extremal regions and MSER criteria. In at least one embodiment, the MSER criteria include minimum and maximum MSER areas, and an acceptable growth rate value for MSER areas. In another embodiment, the MSER criteria include a nested MSER tolerance value.

  • Publication number: 20160070975
    Abstract: Architecture for real-time extraction of maximally stable extremal regions (MSERs) is disclosed. The architecture includes communication interface and processing circuitry that is adapted in hardware to receive a data streams of an intensity image and a depth image in real-time and provide intensity labels for image regions within the intensity image that match a given intensity threshold and provide depth labels for image regions within the depth image that match a given depth threshold. The processing circuitry is also adapted in hardware to find intensity extremal regions within the intensity image based upon the intensity labels and to find depth extremal regions within the depth image based upon the depth labels. The processing circuitry determines strong extremal regions based upon significant overlap between the intensity extremal regions and depth extremal regions. The processing circuitry then determines X-MSER ellipses parameters based upon the strong extremal regions and X-MSER criteria.

  • Patent number: 8895611
    Abstract: The cytotoxic compounds are gold(III) complexes of the type [(diaminocyclohexane)AuCl2]Cl, derived from sodium tetrachloroaurate(III) dihydrate NaAuCl4.2H2O. Specifically, the cytotoxic compounds are gold complexes of isomers of 1,2-diaminocyclohexane, namely cis-(±)-1,2-(diaminocyclohexane)AuCl3, trans-(±)-1,2-(diaminocyclohexane)AuCl3 and S,S-(+)-1,2-(diaminocyclohexane)AuCl3. In order to treat cancer cells in a patient, such as human prostate cancer cells or human gastric cancer cells, an effective amount of the isomer of 1,2-(diaminocyclohexane)AuCl3 is administered to the cancer cells in the patient. The isomer of 1,2-(diaminocyclohexane)AuCl3 is preferably administered with a concentration ranging between about 10 ?M and 20 ?M.

  • Patent number: 7691551
    Abstract: A layer on the reverse side of an imaging member provides excellent crack resistance to the imaging layer(s) on the front side. The crack-deterring backing layer can be a laminated self-adhesive, such as tape, or a coating. Because the crack-deterring backing layer is on the reverse side, it does not affect the electrical properties of the imaging member. Overcoat layers may be used whose function is limited to improved scratch resistance.

  • Patent number: 7219513
    Abstract: The present invention relates to methods for separating and recovering ethane, propane and heavier components from a feed gas, e.g. raw natural gas or a refinery or petroleum plant gas stream or a petrochemical plant gas stream. These methods employ a common new concept which is the use of the turbo-expander shaft compressor to generate the reflux requirement for the cryogenic absorber or distillation columns. The power of the turbo-expander which is absorbed by the shaft compressor is always high enough so that reflux generation by a specific gas compression through the expander shaft compressor and subsequent cooling, condensation and sub-cooling can always be easily maintained. The present invention allows for higher cryogenic absorber pressure and a lower demethanizer/de-ethanizer column pressure thus eliminating the common cryogenic pump at absorber bottom. The present invention ultimately results in a lower residue compression and utilities consumption.
