20090010547 | Image recognition method and image recognition apparatus - The invention provides an image recognition method. First, it is judged whether a set of discrete cosine transform (DCT) coefficients corresponding to an image and/or a set of texture parameters corresponding to the DCT coefficients exist. If the judgment is no, the image is selectively performed a DCT or an inverse discrete cosine transform (IDCT) to generate the set of DCT coefficients based on a format of the image. Based on the set of DCT coefficients, the set of texture parameters is then generated. Afterward, the set of texture parameters is compared with a set of target texture parameters to generate a recognition result. | 01-08-2009 |

20100014761 | Methods And Systems For Discriminating Bands In Scalograms - The present disclosure is directed towards embodiments of systems and methods for discriminating (e.g., masking out) scale bands that are determined to be not of interest from a scalogram derived from a continuous wavelet transform of a signal. Techniques for determining whether a scale band is not of interest include, for example, determining whether a scale band's amplitude is being modulated by one or more other bands in the scalogram. Another technique involves determining whether a scale band is located between two other bands and has energy less than that of its neighboring bands. Another technique involves determining whether a scale band is located at about half the scale of another, more dominant (i.e., higher energy) band. | 01-21-2010 |

20120014611 | SYSTEM AND METHOD FOR DETERMINING PHASE RETRIEVAL SAMPLING FROM THE MODULATION TRANSFER FUNCTION - Disclosed herein are systems, methods, and non-transitory computer-readable storage media for determining phase of an optical system. A system practicing the method performs an analysis of image data of a distant object, wherein the image data is received via an optical system. The system derives at least one parameter of the optical system based on the analysis, and retrieves a phase of the optical system based on the at least one parameter. The parameter can be a ratio Q representing a ration of wavelength times a focal ratio divided by pixel spacing. The image data can be a series of still images. The analysis of the image data can be based on a user input indicating, for example, a position and/or a region in the image data. The image data can be in focus and/or out of focus. In one aspect, slightly out of focus image data is more informative. | 01-19-2012 |

20120201471 | Adaptive Framing for Dynamic Cardiac PET Studies - Methods and computer-readable mediums are provided. In one embodiment, the method acquires patient data. The peak value in the patient data is determined. The patient data is divided into two data segments (i.e., one data segment representing the data before the peak value occurs and a second data segment representing the patient data after the peak occurs). The slopes of the first and second data segments are calculated. Thereafter the slopes are used to determine an appropriate adaptive framing protocol. A number of frames and duration of each frame in the adaptive framing protocol can be calculated or the adaptive framing protocol can be selected from a plurality of framing protocols.

20160086027 | METHOD AND APPARATUS FOR SINGLE-PARTICLE LOCALIZATION USING WAVELET ANALYSIS - Accurate localization of isolated particles is important in single particle based super-resolution microscopy. It allows the imaging of biological samples with nanometer-scale resolution using a simple fluorescence microscopy setup. Nevertheless, conventional techniques for localizing single particles can take minutes to hours of computation time because they require up to a million localizations to form an image. In contrast, the present particle localization techniques use wavelet-based image decomposition and image segmentation to achieve nanometer-scale resolution in two dimensions within seconds to minutes. This two-dimensional localization can be augmented with localization in a third dimension based on a fit to the imaging system's point-spread function (PSF), which may be asymmetric along the optical axis. For an astigmatic imaging system, the PSF is an ellipse whose eccentricity and orientation varies along the optical axis. When implemented with a mix of CPU/GPU processing, the present techniques are fast enough to localize single particles while imaging (in real-time). | 03-24-2016 |
20160188972 | SIGNAL PROCESSORS AND METHODS FOR ESTIMATING TRANSFORMATIONS BETWEEN SIGNALS WITH PHASE ESTIMATION - A phase estimation method estimates the phase of signal components using a point spread function. The method obtains a point spread function that expresses complex frequencies at a non integer location in terms of integral frequencies, for a complex frequency of a signal at a non integer location in a complex frequency domain. It obtains complex frequencies of the signal for the integral frequencies, and computes a sum of products of the complex frequencies of the signal at the integral frequencies with the corresponding complex values of the point spread function to provide an estimate of phase of the signal at the non integer location. | 06-30-2016 |
