The invention relates to a method, to a device, to an imaging module and to a computer program product.

Abstract: A lithographic apparatus comprises an array of individually controllable elements and a data processing pipeline. The array of individually controllable elements modulates a beam of radiation. The data processing pipeline converts a first representation of a requested dose pattern to a sequence of control data suitable for controlling the array of individually controllable elements in order substantially to form the requested dose pattern on a substrate. The data processing pipeline comprises an offline pre-processing device and an online rasterizer. The offline pre-processing device converts the first representation of the requested dose pattern to an intermediate representation, which can be rasterized in a fewer number of operations than the first representation. The storage device stores the intermediate representation.

In addition, the image processing method improves the raw images of the sensor using image-sharpening methods and/or contrast-enhancing methods, so that display on a display arrangement is made possible for viewing by a viewer.

Abstract: One embodiment of the present invention provides a system that deposterizes a posterized image. During operation, the system receives a posterized image, wherein pixels in the posterized image have color values that belong to a set of posterized color values, which is a subset of a set of possible color values for the deposterized image. Next, the system generates a deposterized image from the posterized image, wherein color values in the deposterized image are not restricted to the set of posterized color values and instead can be selected from the entire set of possible color values to reduce artifacts caused jumps in color values that arise from posterization. While generating the deposterized image, the system selects color values for pixels in the deposterized image so that the deposterized image can be reposterized to restore the original posterized image.

Abstract: A 2D transform and its inverse have an implementation as a sequence of lifting steps arranged for reduced computational complexity (i.e., reducing a number of non-trivial operations). This transform pair has energy compaction properties similar to the discrete cosine transform (DCT), and is also lossless and scale-free. As compared to a separable DCT transform implemented as 1D DCT transforms applied separably to rows and columns of a 2D data block, the transforms operations are re-arranged into a cascade of elementary transforms, including the 2×2 Hadamard transform, and 2×2 transforms incorporating lifting rotations. These elementary transforms have implementations as a sequence of lifting operations.

Abstract: A method and apparatus that allows for the identification and correction of defective pixels and/or pixel clusters in an imaging device. The method, and implementing apparatus determines that a pixel is defective based upon a comparison of its pixel signal value with the value of neighboring pixels. In one exemplary embodiment, a pixel is defective if it is beyond a pre-determined threshold of either a high or low value from its neighboring, corrected pixels. Pixels identified as defective can be corrected using exemplary methods of the invention such as substituting a value of the defective pixel with a value of one of its non-defective neighbors.

Abstract: The border of object in an image is blurred and so the modulation transfer function (MTF) of an image is reduced due to the blurred border. This present invention provides a deductive method for determining a border of an object in an image. Then the border of the object therein is amended and so the MTF of image is increased. In regard to an increasingly changeable color image, the present invention provides a deductive method in deciding upon a gray scale of the image to increase the color accuracy in amending an image.

Abstract: A direction of an intended edge is determined, and a position of the intended edge is corrected to a position that brings a direction that connects a position of the intended edge and a position of an adjacent edge closer to the determined direction of the intended edge, and edge information representative of an area of the edge of an enlarged image is generated by using the corrected position of the edge. Gradation data before and after filtering are synthesized at a rate corresponding to a feature quantity representative of the amount of pixels within a predetermined color area. The gradation data of the plural pixels within a predetermined region including the position of the intended edge to be sharpened among the interpolated gradation data of the respective pixels on the interpolated image is sharpened at a degree corresponding to the number of pixels of the uninterpolated image.

Abstract: Apparatus and method for rapid interactive viewing of a digital image over a network. A client computer displays a view of an image. The image is originally resident on a server computer. The client computer maintains a cache, initially empty, of image blocks already obtained from the server. When the client computer is asked to render a view of a particular portion of the image at a particular resolution, it first ascertains if any image blocks in the image-block cache intersect the requested view. It then computes the residual area of the view resulting from subtracting out from the view the intersecting portions of cached image blocks, and, if the residual area is positive, downloads from the server computer a set of image blocks comprising the residual portion of the view at the given resolution.

Abstract: A system analyzes multiple images to identify similar images using histograms, image intensities, edge detectors, or wavelets. The system retrieves labels assigned to the identified similar images and selectively concatenates the extracted labels.

Abstract: A method for adaptive video processing includes identifying an object in a frame of video data, determining an object confidence value associated with the identified object, and determining if the object confidence value meets a predefined threshold object confidence value. If not, the method can further include repeatedly processing the frame of video data with additional processing algorithms, and again identifying the object, determining an updated object confidence value, and determining if the updated object confidence value meets the predefined threshold object confidence value, until the updated object confidence value meets the predefined threshold object confidence value. Thereafter, an event can be identified based upon the identified object and an object primitive defining a relationship between the identified object and one or more other objects in the frame of video data, where the events can be identified in accordance with a hierarchical event structure.
