摘要： An image processing method in which OCR is used to guide the text tokenization. More particularly, OCR is first performed on each symbol in the scanned image. For example, a symbol may be a number, letter, or other character. During the tokenization process, the OCR results are used to select appropriate matching criteria for each symbol. The symbols that are recognized as different characters are not allowed to be clustered into the same group. The symbols with the same OCR results are clustered according to the recognition confidence levels.

摘要： A system and method for character recognition with document orientation determination is shown. The method is a detection of simple page orientation based on a limited version of character recognition. The method includes binairizing an input image which has a plurality of alphanumeric characters with a first orientation. The method continues with extracting the connected components and determining a second orientation where the second orientation is based on a 90° turn clockwise or counterclockwise or, in the alternative, no turn from the first orientation. The second orientation will result in a 180° variance from the proper orientation or it will be the proper orientation. The method continues with implementing a limited version of optical character recognition for an analysis of a character and determining if that second orientation is upside down, based at least in part on the analysis. This method generally uses the character “i” for analysis. However, for documents that have a limited number of “i”s, e.g. such as Russian documents or documents with all capital letters, the “T” may also be used.

摘要： What is disclosed is a novel system and method for augmenting present methods used for determining the orientation direction automatically being detected of digital pages of a plurality of scanned documents in a digital document processing environment. The present method takes advantage of the observation that pages scanned in data processing centers are often highly correlated. The present method contains five primary steps. 1) Page orientation (i.e., up/down) is detected using a traditional method. 2) Each page is classified as either directional or non-directional. 3) The pages classified as directional are clustered into groups. 4) The direction for each group is determined. 5) The directional group's direction is used to revise the orientation for pages contained in the group. Through the implementation of the teachings hereof, performance, in terms of both speed and accuracy, are very high relative to current methods and detection error rates can be reduced significantly.

摘要： An assessment authoring system implemented by an operative set of processor executable instructions configured for execution by at least one processor includes a user interface and an assessment generation component. The user interface communicates user input and the assessment generation component receives the user input from the user interface. The assessment generation component generates an assessment data structure for printing on a multifunction device. The printed assessment includes a marking region adapted to receive a human marking. The system may utilize a model or rubric that can be used to score the human marks when are processed by image processing.

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 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： 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 ink jet printhead having an integral membrane filter fabricated over the surface of the printhead containing the ink inlet is disclosed. The individual printheads are obtained by a sectioning operation which cuts aligned and bonded channel and heater wafers. The mated wafers contain a plurality of printheads and must be separated. The integral membrane filter is formed on the channel wafer after it is anisotropically etched incorporating the etch resistant mask layer and prior to mating with the heater wafer. A patternable layer is deposited over the etch resistant masking layer and exposed, patterned and developed to establish the mesh filter. In one embodiment, the side of the channel wafer not patterned and etched is heavily doped to form an etch stop which increases the robustness of the membrane filter by ensuring that the masking layer remains intact during subsequent fabricating steps. This doped region beneath the patternable layer is then etched using the membrane filter as a mask to open the filter pores through the doped layer of the channel wafer, thereby increasing the filter thickness and its overall strength.
