摘要： An image editor stores color pixels for an image to be edited in an image pixel buffer and a lookup register bank. The stored image is displayed on a monitor. An operator uses a mouse to designate a screen path that identifies an object in the image, and pixel position data is detected for the screen path. A programmed computer determines in real time one or more criteria for a search controller on the basis of hue, saturation and luminance variables which are determined from the stored pixel color data for pixels along the screen path. The computer further searches the image pixels to identify the object and its boundaries in accordance with the search controller criteria, and applies color edit actions to the identified object within the image.

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： A relevance based print integrity method includes comparing current raster image data that define a document to be printed with golden raster image data that define a previous version of said document with a known (perfect) quality. A plurality of differences between said current raster image data and said golden raster image data are calculated, and each of the differences is processed to determine a relevance value of the difference and to assign the relevance value to the difference. The method includes generating and storing a list of the differences, wherein the list is ordered in terms of the relevance value assigned to each difference. The difference list is presented to a user textually or graphically and/or is used to control or interrupt printing operations.

摘要： A collaboration detection system and a method for detecting collaboration amongst a class of two or more students in answering a plurality of problems of an assessment administered to the students are provided. The system includes a tangible processor and a memory with instructions to be executed by the tangible processor. The processor executes the instructions for accessing granular assessment data associated with each student. The granular assessment data includes an independent determination of correctness of the answer submitted by the student for each respective problem of the plurality of problems of the assessment. The processor then executes the instructions for determining for each combination of students of the class of students the number of problems for which it was determined that the same problem was answered incorrectly by all of the students of the combination of students.

摘要： A system for electronically distilling information from a business document uses a network scanner to electronically scan a platen area, having a business document thereon, to create a bitmap. A network server carries out a segmentation process to segment the scan generated bitmap into a bitmap object, the bitmap object corresponding to the scanned business document; a bitmap to text conversion process to convert the bitmap object into a block of text; a semantic recognition process to generate a structured representation of semantic entities corresponding to the scanned business document; and a document generation process to convert the structured representation into a structure text file. The semantic recognition process includes the processes of generating, for each line of text having a keyword therein, a terminal symbol corresponding to the keyword therein; generating, for each line of text not having a keyword therein and absent of numeric characters, an alphabetic terminal symbol; generating, for each line of text not having a keyword therein and having a numeric character therein, an alphanumeric terminal symbol; generating a string of terminal symbols from the generated terminal symbols; determining a probable parsing of the generated string of terminal symbols; labeling each text line, according to a determined function, with non-terminal symbols; and parsing the business document information text into fields of business document information text based upon the non-terminal symbol of each text line and the determined probable parsing of the generated string of terminal symbols.

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： 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.

摘要： A method backfills areas of an image with synthesized textures. This is realized by selecting a texture exemplar from an image and identifying an area of the image to be backfilled. An estimate of the synthesized texture is generated and predetermined spatial domain constraints are applied to the estimate. The spatially constrained estimate is operated upon by a Fourier transform to create a spectral function. Predetermined spectral domain constraints are applied to the spectral function and an an inverse Fourier transform is performed thereon to produce a synthesized texture. The synthesized texture is inserted into the area of the image to be backfilled if it is determined to be adequate. If the synthesized texture is inadequate, the synthesized texture is put through the synthesis process again until the the texture is adequate for backfilling.
