摘要： A method of text extraction in color compound documents is described. The method connects similarly colored pixels of an image of a color compound document into connected components (CCs); classifies each CC as either text or non-text; refines the text CC classification for each text CC using global color context statistics; groups text CCs into text blocks; recovers misclassified non-text CCs into a nearby text block; and removes extraneous CCs from each text block using local color context statistics to thereby provide the extracted text in the text blocks. Also described is a method of locating graphics objects in a color compound document image.

摘要： Disclosed is a computer implemented method of text extraction in colour compound documents. The method connects similarly coloured pixels of an image of a colour compound document into connected components (CCs); classifies each CC as either text or non-text; refines the text CC classification for each text CC using global colour context statistics; groups text CCs into text blocks; recovers misclassified non-text CCs into a nearby text block; and removes extraneous CCs from each text block using local colour context statistics to thereby provide the extracted text in the text blocks. Also disclosed is a computer implemented method of locating graphics objects in a colour compound document image. The method connects similarly coloured pixels of said image into connected components (CCs) and placing the CCs in an enclosure tree; classifies (330,730) each CC into one of a plurality of classes wherein at least one class (862) represents salient graphics components; identifies (1140) a graphics container (441) to perform semantic analysis for each CC of said class representing salient graphics components; profiles (1170) descendents of said graphics container in said tree to obtain semantic context statistics; and decides (1710) whether the graphics container contains a whole or part of a graphics object based on said semantic context statistics.

摘要： A method (199) is disclosed for modifying colors of text extracted from an image of a document page to improve visual quality. The document image comprises text and image regions of various colors. The method divides (100) the document image into a plurality of connected components, the connected components comprising pixels of similar color that are closely spatially located, and selects from the image a plurality of the connected components that represent text. The plurality of text connected components are grouped to form a logical structure grouping of said page comprising one or more text blocks wherein each said text block represents a text line or paragraph. One or more logically consistent color sets are then formed (120, 699, 399, 499) for each text block based on the colors of the connected components in the text block. The logically consistent color sets represent all text of visually similar color of the corresponding text line or paragraph. The method then applies color enhancement (130) to the logically consistent color sets to enhance visual quality and correct image defects in the document image.

摘要： Disclosed is a method of classifying segmented contents of a scanned image of a document. The method comprise partitioning the scanned image into color segmented tiles at pixel level. The method then generates superpositioned segmented contents, each segmented content representing related color segments in at least one color segmented tile. Statistics are then calculated for each segmented content using pixel level statistics from each of the tile color 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. Each of a plurality of tiles of predetermined size of the image are converted into a representation having a plurality of layers, the representation corresponding to at least one said tiles comprising multiple colored layers, each tile comprising a superposition of the corresponding colored layers. For each of the colored layers, merging is performed with adjacent ones of the tiles, thereby generating a multi-layered document representation.

摘要： An apparatus and method for estimating and compensating sampling frequency offset are disclosed. Particularly, a linear mathematical scheme is employed to calculate the related phase difference for saving use of multipliers and storage circuit used for sampling frequency offset estimation and compensation in the conventional art. The preferred embodiment of the invention has a first step to receive signals by the offset estimating circuit. Next, the phase value for each signal is calculated, and the pilot signal therein is retrieved. Next, a phase difference is obtained by subtraction operation between the received symbols and the delayed pilot symbols. And a circuit for storing the phase differences is incorporated. Next, a phase difference between the adjacent symbols is obtained by accumulating the phases and processing the least-error-sum-of-squares operation. Therefore, an estimation value of the sampling frequency offset of a communication system is obtained, and further to compensate the offset.

摘要： Disclosed is a method of detecting a predetermined mark embedded in an image. The mark (29) comprises a predetermined arrangement of a plurality of elements (30), each element having a predetermined colour characteristic and predetermined shape. The method processes (20) the image to provide an encoded representation of the image at a predetermined resolution (eg. 200 dpi). The coordinate positions for substantially each of the elements of the mark embedded in the image are detected (22), wherein the detection is characterised by applying at least one mask (80) to substantially each pixel of the encoded representation. From the coordinate positions, a set of spatial features representing a spatial arrangement of the detected elements are then determined (23). The determined set of spatial features is then compared (24) to a known set of spatial features to provide a confidence level measure for a degree of matching between the known set and the determined set of spatial features.
