  • Patent number: 10268914
    Abstract: Described is a blind sensing system for hyperspectral surveillance. During operation, hyperspectral data is captured using a hyperspectral camera as mounted on a mobile platform. The system then forms a signal mixture of a plurality of multi-dimensional signals. The multi-dimensional signals being the captured hyperspectral data of a wide area having a background and an object. The plurality of multi-dimensional signals are then demixed using blind source separation, resulting in separated spectra. Finally, the system detects and recognizes a spectral signature of the object in the separated spectra.

  • Patent number: 10264256
    Abstract: Methods, systems, and computer programs for improved quality video compression. Image quality from MPEG-style video coding may be improved by preserving a higher number of bits during intermediate encoding and decoding processing steps. Problems of inverse discrete cosine transform (IDCT) mismatch can be eliminated by exactly matching the IDCT function numerical algorithm of the decoder to the IDCT function numerical algorithm used for the decoding portion of the encoder. Also included is an application of high precision compression to wide dynamic range images by extending the range of the “quantization parameter” or “QP”. The extension of QP may be accomplished either by increasing the range of QP directly, or indirectly through a non-linear transformation. Also included is an application of extended intermediate processing precision and an extended QP range to reduced contrast regions of an image to extend the precision with which the low-contrast portions are compression coded.

If the overall time estimate is greater than a threshold value, then an algorithm time estimate for each of two or more algorithms of the set of machine-vision algorithms is obtained. A rank associated with each of the two or more algorithms is computed based on the algorithm time estimates. A designated algorithm to be performed on the worker is selected based on the rank associated with each of the two or more algorithms.

  • Patent number: 10122946
    Abstract: When detecting particulate radiation, such as electrons, with a pixelated detector, a cloud of electron/hole pairs is formed in the detector. Using the signal caused by this cloud of electron/hole pairs, a position of the impact is estimated. When the size of the cloud is comparable to the pixel size, or much smaller, the estimated position shows a strong bias to the center of the pixel and the corners, as well to the middle of the borders. This hinders forming an image with super-resolution. By shifting the position or by attributing the electron to several sub-pixels this bias can be countered, resulting in a more truthful representation.

    Abstract: Systems and methods for restoring the appearances of scans of damaged physical documents. Ink bleed is removed and/or ink added to portions of a scanned image based on determining an ink bleed model by analyzing colors of pixels in the scanned image. Gaps in strokes are reconstructed based on analyzing pixel color at multiple angles around individual pixels in the scanned image to determine whether the individual pixels are part of a stroke. The appearance of the scanned image is also enhanced by comparing pixels that are not already close to a background color or ink color with other nearby pixels and, based on the nearby pixels, adjusting colors of the pixels that are not already close to the background color or ink color. These techniques are used individually or in combination to improve the appearance of the scanned image.

  • Patent number: 9984313
    Abstract: Embodiments herein provide computer-implemented techniques for allowing a user computing device to extract financial card information using optical character recognition (“OCR”). Extracting financial card information may be improved by applying various classifiers and other transformations to the image data. For example, applying a linear classifier to the image to determine digit locations before applying the OCR algorithm allows the user computing device to use less processing capacity to extract accurate card data. The OCR application may train a classifier to use the wear patterns of a card to improve OCR algorithm performance. The OCR application may apply a linear classifier and then a nonlinear classifier to improve the performance and the accuracy of the OCR algorithm. The OCR application uses the known digit patterns used by typical credit and debit cards to improve the accuracy of the OCR algorithm.

  • Patent number: 9948828
    Abstract: A subject is imaged repeatedly and color images of the subject are obtained. A color histogram is generated from the color subject image obtained and a representative color is decided from the color histogram generated. A specific color range that can be considered a color identical with the representative color is decided from the color histogram and representative color. Color outside the specific color range in the color subject image is changed to gray, an image of the subject in which the non-specific colors have been changed to gray is obtained and the image is displayed. Processing such as deciding the specific color range is repeated. When an instruction to fix the specific color is issued, the specific color range is fixed.

  • Patent number: 9948933
    Abstract: In general, this disclosure describes techniques for coding video blocks using a color-space conversion process. A video coder, such as a video encoder or a video decoder, may determine whether to use color-space conversion for a coding unit and set a value of a syntax element of the coding unit to indicate the use of color-space conversion. The video coder may apply a color-space transform process in encoding the coding unit. The video coder may decode the syntax element of the coding unit. The video coder may determine whether a value of the syntax element indicates that the coding unit was encoded using color-space conversion. The video coder may apply a color-space inverse transform process in decoding the coding unit in response to determining that the syntax element indicates that the coding unit was coded using color-space conversion.

  • Patent number: 9916646
    Abstract: An image processing system for generating a high dynamic range image from a first image and a second image is presented. The system comprises a first displacement estimator adapted to estimate a displacement of image content between a reference image derived from the first image and an image to be warped derived from the second image. The system comprises a first warping unit that compensates the estimated displacement by warping the image to be warped resulting in a first warped image. The system comprises a first error detector adapted to detect geometric warping errors within the first warped image and a first error compensator adapted to compensate the estimated geometric warping errors within the first warped image resulting in a first error corrected image. The system comprises a high dynamic range calculator adapted to calculate the high-dynamic range image based upon the first error corrected image and the reference image.

    Abstract: An image processing pipeline may apply chroma suppression to image data at a scaler implemented in the image processing pipeline. Image data collected for an image may be received at a scaler that is encoded in a color space that includes a luminance component and chrominance components. When resampling the image data to generate a different size of the image, the scaler may attenuate the chrominance components of the image data according to the luminance component of the image data. The scaler may also perform dot error correction and convert the image data from one subsampling scheme to another.

  • Patent number: 9857953
    Abstract: In embodiments of image color and tone style transfer, a computing device implements an image style transfer algorithm to generate a modified image from an input image based on a color style and a tone style of a style image. A user can select the input image that includes color features, as well as select the style image that includes an example of the color style and the tone style to transfer to the input image. A chrominance transfer function can then be applied to transfer the color style to the input image, utilizing a covariance of an input image color of the input image to control modification of the input image color. A luminance transfer function can also be applied to transfer the tone style to the input image, utilizing a tone mapping curve based on a non-linear optimization to estimate luminance parameters of the tone mapping curve.
