摘要: A processor is programmed for accessing data-items from a matrix of rows and columns, access being constrained to a moving window. A cache memory caches data for the window. The cache memory makes a location used for a first data-item from an earliest row available for reuse when the window moves along the row direction, and retrieves a second data item for a latest row of the window into the cache memory. Data for the latest row may be written into the location just made available for reuse. The position of the first data-item along the row direction of the matrix trails the position of the second data-item along the row direction of the matrix at least by the width of the window.

摘要: A sampling system adapts the sampling rate for sampling analog signals and/or the stored number of samples to the fixed or video image content, such that a higher rate, and equivalently a larger number of samples, are acquired for an image or video segment containing higher spatial frequencies while a lower number of samples (lower sampling rate) are retained for image or video segments containing lower spatial frequencies. The Nyquist theorem may still be satisfied for each individual image segment, while information necessary for edge enhancement is retained.

摘要: A system and method for generating a health insurance explanation of benefits for a patient is provided for receiving one or more adjudicated claims from a health insurance company; analyzing the one or more claims in relation to patient information stored in a patient records database; and generating a personalized message to the patient about the patient's health care based on the stored patient information and the adjudicated claims. The personalized message, applied to an EOB generation system associated with the health insurance company, forms a part of an enhanced EOB to be provided to the patient.

摘要: A video signal processor enhancing video information evaluates candidate vectors of enhancement algorithms utilizing an error function biased towards spatio-temporal consistency with a penalty function. The penalty function increases with the distance—both spatial and temporal—of the subject block from the block for which the candidate vector was optimal. Enhancements are therefore gradual across both space and time and the enhanced video information is intrinsically free of perceptible spatio-temporal varying artifacts.

摘要: A method to enhance motion estimation is provided. The method includes providing a motion estimator, obtaining at least two candidate motion vectors from the motion estimator and applying an error function having a penalty that depends on the position and size of the candidate motion vectors. A device for recursive motion vector estimation having enhanced convergence is also provided. The device includes a vector generator and a best vector selector. The best vector selector comprises means to evaluate candidate motion vectors by applying an error function having at least a penalty that depends on the position and size of the candidate motion vectors.
