摘要： Methods for generating an image mosaic are provided. In one respect, pixels saliency of a first image and a second image are determined. One salient pixel may be selected from the determined pixels saliency group of the first image and one salient pixel may be selected from the determined pixels saliency group of the second image. A mosaicking technique of the first and second image may be performed if the one salient pixel of the first image and the one salient pixel of the second image are registered successfully.

摘要： A method of recognizing a handwritten word of cursive script comprising providing a template of previously classified words, and optically reading a handwritten word so as to form an image representation thereof comprising a bit map of pixels. The external pixel contour of the bit map is extracted and the vertical peak and minima pixel extrema on upper and lower zones respectively of this external contour are detected. Feature vectors of the vertical peak and minima pixel extrema are determined and compared to the template so as to generate a match between the handwritten word and a previously classified word. A method for classifying an image representation of a handwritten word of cursive script is also provided. Also provided is an apparatus for recognizing a handwritten word of cursive script. This apparatus comprises a template of previously classified words, a reader for optically reading a handwritten word, and a controller being linked thereto for generating a match between the handwritten word and the previously classified words. Two algorithms are provided for respectively correcting the skew and slant of a word image.

摘要： Methods, computer program products, and systems are presented. The methods include, for instance: obtaining an unmarked questionnaire form and creating form metrics data of the unmarked questionnaire form, receiving a selection marked form having freehand marks and determining selections data by quantifying a center point of a freehand mark and by comparing the center point with the form metrics data. Selections data may be adjusted according to positional consistency amongst the freehand marks if one mark is ambiguous as to the distances to answer choices.
