摘要： A method of reducing blurring in an image of size greater than M columns by N rows of pixels, comprises deriving a blur kernel k representing the blur in the image, and deriving an inverse blur kernel k -1 . The inverse blur kernel is given by (I) where h(m) is the sum of the first m terms of the series (II) δ is the Dirac delta, m is greater than 1, and h(m) is a two dimensional matrix of size M x N. The two dimensional matrix h(m) is convolved with the image over the whole image in the image pixel domain to produce an image with reduced blur. The method may be applied to a video sequence allowing the sequence of images to be deblurred in real time.

摘要： In one implementation, a graphical object classification system includes an acquisition module, a signature generation module, and a classification module. The acquisition module accesses a representation of a graphical object. The signature generation module generates an appearance-invariant signature of the graphical object based on the representation. The classification module classifies the graphical object based on the appearance-invariant signature.

摘要： Embodiments of the present invention are directed to efficient video processing methods and systems for computationally efficient denoising, sharpening, contrast enhancement, deblurring, and other spatial and temporal processing of a stream of video frames. Embodiments of the present invention separate statistics-related calculations, including estimation of pixel-value-associated variances, standard deviations, noise thresholds, and signal-contrast thresholds, carried out on only a small percentage of video frames selected at a fixed or variable interval from the video stream, from various spatial and temporal processing steps carried out on each frame of the video stream. In certain embodiments of the present invention, the statistics-related calculations are carried out by the general processor or processors of a computer system, while the frame-by-frame spatial and temporal processing is carried out by one or more specialized graphics processors within the computer system.

摘要： Provided are systems, methods and techniques which use local image properties to determine which potential defects in an image should be corrected. In one representative embodiment, potential defects in an image are identified based on edge sharpness, and measures of strength for the different potential defects are calculated. The measures of strength for the potential defects are then evaluated in view of certain local properties of the image, in an immediate vicinity of such potential defects, in order to identify the image defects to be corrected.
