20090080798 | PROCESSING AN INPUT IMAGE TO REDUCE COMPRESSION-RELATED ARTIFACTS - In a method for processing an input image to reduce compression-related artifacts, a plurality of block transforms of the input image having respective plurality of block-grid locations are generated, where each of the block-grid locations is shifted with respect to the block-grid locations in each of the other block transformed images. In addition, a plurality of respective intermediate transform domain filtered images having modified transform coefficients are generated. Per-pixel relative weights are assigned to each of the intermediate transform domain filtered images, where each of the intermediate transform domain filtered images has different contexts, and where the per-pixel relative weights are adaptive to the local context in each of the intermediate transform domain filtered images. Moreover, a weighted average of inverse-transforms of the intermediate transform domain filtered images from the per-pixel relative weights to produce an artifact-reduced image is calculated and the artifact-reduced image is outputted. | 03-26-2009 |
20100003045 | ELECTROGRAPHIC DOT GAIN AND OPTICAL DENSITY DECOUPLING METHOD, XEROGRAPHIC IMAGE REPRODUCTION, AND SYSTEMS, METHODS AND SOFTWARE RELATED THERETO - A method is provided for decoupling the control of dot gain and optical density in electrophotographic based printing by varying the exposure level for each dot in an image. | 01-07-2010 |
20100266212 | Estimating Vanishing Points in Images - A digital image is processed to provide an estimation of the position in the image plane of a vanishing point. The processing includes detecting pairs of similar image patches and identifying a concurrent set of straight virtual lines that substantially converge at a point on the image plane, each line passing through a pair of similar image patches within the image. | 10-21-2010 |
20110085742 | FAST IMAGE RESOLUTION ENHANCEMENT WITH DE-PIXELING - An output image that corresponds to a higher-resolution version of a source image is produced. In this process, source pixels of the source image are processed with a set of linear non-separable filter kernels to produce the output image with a corresponding output pixel block of constituent output pixels for each of the source pixels. The set of filter kernels has a mean substantially equal to an identity filter such that a downscaling of the of the output image to a resolution level of the source image produces a downscaled image that is substantially identical to the source image. For each of the source pixels, each of the filter kernels in the set is applied to a local neighborhood of the source pixel to produce a respective value of each of the constituent output pixels of the corresponding output pixel block. | 04-14-2011 |

20120257265 | One-pass filtering and infrared-visible light decorrelation to reduce noise and distortions - A scanning device includes a scanning mechanism and a processing mechanism. The scanning mechanism scans an image fixed on a medium to generate a digital infrared representation of the image and a digital visible light representation of the image. The processing mechanism substantially reduces effects of noise and distortions within the digital visible light representation of the image in one pass. The processing mechanism at least decorrelates visible light aspects from the infrared representation of the image and employs a one-pass filter that uses both the infrared and the visible light representations of the image. | 10-11-2012 |

20140096146 | TRANSLATING TIME-STAMPED EVENTS TO PERFORMANCE INDICATORS - Systems and methods for translating time-stamped events to performance indicators are provided. A data component can receive sequences of time-stamped events associated with a device with a set of subsystem components. A conversion component can convert the sequences to time series based upon log transformations of event-intervals associated with the events. An estimation component can estimate local event-descriptor distribution characteristics at an event count associated with the time series. A translation component can translate the local event-descriptor distributions characteristics into performance indicators. | 04-03-2014 |
20140114609 | ADAPTIVE ANALYSIS OF SIGNALS - Data streams that can be related to operation tracing and/or performance indications, for example, may be monitored. The data streams can have different dynamic statistical characteristics including static signal distributions and non-static signal distributions with respect to time. The data streams may be analyzed independent of any predetermined assumptions on statistical behavior and on changes in the statistical behavior. Data may be transformed into a set of key performance indicators and performance-change indicators that are adaptive to instantaneous statistical changes. | 04-24-2014 |
20140115398 | ANALYSIS OF HEALTH INDICATORS OF A SYSTEM - A signal from a system, such as a reactive system, that reflects health indicators of the system may be selected. A signal analyzer may extract the health indicators from the signal and conduct a diagnostics of the health of the system based on the health indicators. | 04-24-2014 |
