摘要： A method for removal of punched hole artifacts in digital images includes, for a scanned document page, deriving an original digital image that defines the page in terms of a plurality of input pixels. A reduced resolution bitonal image is generated from the original image. The method further includes providing for identifying of candidate punched hole artifacts in the reduced resolution bitonal image and providing for testing the candidate punched hole artifacts for at least one of shape, size, and location. Where a candidate punched hole artifact meets the at least one test, the method includes generating a modified image. This includes erasing the candidate punched hole artifact from the original digital image.

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： A method and system for automatically helping a teacher/educator evaluate assessments administered to students for determining student's attributes. The teacher/educator reviews stored assessment forms at a digital user interface (DUI) at a multifunction device (MFD) and selects the desired forms and creates an Assessment Batch which includes a List of Students to be given the forms for marking. The system automatically codes each form with personalized student information and prints the individualized assessment forms. The system may include an assessment repository for storing assessment definitions, rubrics, and administered assessments (e.g., results sheets), an may additionally or alternatively include an assessment analyzer for interpreting scanned imaged of administered assessments. The teacher/educator administers the assessment and assessment forms are manually marked, collected and scanned at the MFD, entered into storage and the marked images automatically analyzed and the assessments automatically evaluated from stored rubrics and the teacher/educator is automatically notified by email that the evaluation has been performed. The system enables the teacher/educator to review the evaluations remotely and validate/annotate the evaluation and update the records in storage. The Assessment Batch may be created for a list of students in a group, a class, a grade level, a school, a plurality of schools and students in a geographical area.

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.
