摘要： This invention provides a device and method for processing data with a data processing string having push type and pull type tasks. Push tasks processes data and pushes the output of the process to downstream push tasks based on link paths. On the other hand, pull tasks sends data requests via upstream links to upstream pull tasks to acquire data for processing. Data processing strings are usually configured with either push tasks and/or pull tasks to maintain consistency in the direction of links. The preferred embodiments of this invention provides a method and apparatus for inserting push tasks in a string of pull tasks and inserting pull tasks in a string of push tasks. The inserted push and pull tasks are enhanced with forward and backward message links and interface tasks are provided to interface between the inserted pull or push tasks in the strings of push or pull tasks, respectively.

摘要： A method for varying the color of an image including lines and background. Where the image includes the colors black and white and a plurality of gray pixels, where gray refers to the presence of pixel values between the maximum and minimum pixel values, inclusive, the image is first converted to a color space, such as for example, r, g, b (red-green-blue). Pixel values are thresholded for differentiation between lines and background. When pixels have a value indicating that the pixel is background, that pixel is set to a background color that has been previously selected. Otherwise, that pixel is set to a foreground color. The result is that background is set to a single color, and lines are set to a second color. Alternatively, where intermediate values are present, the foreground color value may be added to the intermediate level color value to produce a gradually varying colored line.

摘要： A period-based method for converting digital image data for a plurality of pixels from a first bit depth to a second bit depth includes receiving an input scanline of an arbitrary length comprising digital image data for a plurality of input image pixels. Each of the input image pixels is defined at the first bit depth. The input scanline is divided into a plurality of periods each comprising digital image data for a select number of input image pixels. The period is selected so that the image data for the select number of input image pixels exactly comprises m bytes when defined at the first bit depth and exactly comprises n bytes when defined at the second bit depth, wherein m and n are different integers. For each of the periods in succession, the image data for each of the select number of input image pixels is converted from the first bit depth to the second bit depth. A code generator generates hard-coded conversion operating instructions and a look-up table for specified bit conversion operations and generic conversion operating instructions for all other bit conversion operations.

摘要： A scheme that generates image processing source code for custom applications automatically by using structured image (SI) technology in a way that takes advantage of the unbound and incomplete features of SI. Resulting custom applications developed by this method can be defined and converted to running source code in minutes, or shipped to a co-user of the system in a compact portable form for remote code generation.Nested sub-component references and associated image processing operations necessary to generate an output raster image are obtained from a structured image template. Image processing operations and the order of said operations within an image processing definition are stored within the structured image definition. Unbound structured image references to undefined component objects and incomplete structured image references to image processing operations and parameters not explicitly defined within said structured image are input options. Source code is generated from structured image definition language automatically utilizing a modified structured image render program which analyzes said structured image definition language. The code can be used for further rendering or code modification activities.

摘要： A method and device for describing a complex color raster image as a collection of objects in a hierarchical and device independent format. The purpose of structured imaging (SI) is to expand the scope of a raster image to a collection of individually manipulable component objects. An SI is a hierarchical description of a single output image raster which may be used as one component of a page in a structured document. Objects contributing to the output raster may originate from text, graphics, other rasters or a combination thereof, and all maintain their heritage for selectability and modification. The SI describes not only the source data but also the image processing operations required for rendering the output raster. SI technology supports re-editability, customization and enhancement, automatic image assembly and high performance imaging. Thus, such a model has implications not only in an image editing and processing arena, but also in the filing and printing services used for image handling.

摘要： An image editor includes a pixel buffer for storing color data for an image to be edited. A monitor screen displays the image and an active area having a graphic that represents two color descriptor variables. A pair of overlays controls the respective color descriptor variables singly or together. In one embodiment, the active area is a circle with a color wheel about which hue varies angularly and along the radius of which chroma varies. A radial overlay line controls hue and a concentric radially movable ring controls chroma. In another embodiment among others, the active area is a square with a checkerboard graphic. Black and white squares within the checkerboard indicate increasing brightness in the vertically upward direction and increasing contrast in the rightward horizontal direction. Horizontal and vertical hairline overlays control the brightness and contrast, respectively.

摘要： The present invention describes a method for automatic cropping of images containing regions where intensity levels are uniform and other regions where intensity levels vary considerably. An image to be automatically cropped is scaled down to a grid and divided into non-overlapping blocks. The mean and variance of intensity levels are calculated for each block. Based on the distribution of variances in the blocks, a threshold is selected for the variance. All blocks with a variance higher than this threshold variance are selected as regions of interest. The regions of interest are then cropped to a bounding rectangle.
