Abstract: Disclosed is a method of classifying segmented contents of a scanned image of a document. The method comprise partitioning the scanned image into colour segmented tiles at pixel level. The method then generates superpositioned segmented contents, each segmented content representing related colour segments in at least one colour segmented tile. Statistics are then calculated for each segmented content using pixel level statistics from each of the tile colour segments included in segmented content, and then determines a classification for each segmented content based on the calculated statistics. The segmented content may be macroregions. The macroregions may form part of a multi-layered document representation of the document.

Abstract: A method (1100) of creating a document comprising a modifiable shape, is disclosed. The method analyses an image to detect at least a graphical object. The method matches the detected graphical object with at least one of a plurality of predetermined modifiable closed-form non-textual template shapes (e.g., 420) comprising control parameters for modifying the closed-form non-textual template shape in a non-affine manner. The number of control parameters of the predetermined modifiable closed-form non-textual template shape is less than the number of sections making up the modifiable closed-form non-textual template shape. The method creates a document comprising the at least one modifiable closed-form non-textual template shape.

Abstract: A method (1100) of creating an editable document is disclosed. The method analyses a bitmap image to detect at least one bit map representation of a graphical object and a bitmap representation of a line object. The method matches the graphical object with one of a plurality of predetermined template shapes (e.g., 420), the template shape having one or more predetermined non-contiguous connection points. The method selects one of the predetermined connection points for the line object if at least one end of the line object is within a predetermined distance of the selected connection point and associates the line object with the selected connection point. The method creates an editable document comprising the template shape with the line object connected thereto, wherein the line object remains associated with the selected connection point upon the template shape being modified within the document such that the line object remains dynamically connected to the template shape.

Abstract: A method (100), an apparatus, and a computer program product for automatically producing a compact representation of a colour document are disclosed. In the method, a digital image of a colour-document page is segmented (110) into connected components in one-pass, block raster order. The digital image of the page is partitioned into foreground and background images using layout analysis (120) based on compact, connected-component statistics of the whole page. At least one portion of the background image where at least one portion of the foreground image obscures the background image is inpainting (520) in one-pass block raster order. The foreground and background images are combined (130) to form a compact document. A method, an apparatus, and a computer program product for segmenting a digital image comprising a plurality of pixels are also disclosed.
