    摘要: A method of document segmentation. Specifically, one embodiment of the present invention discloses a method of document segmentation that performs a plurality of projection profiles of pixel intensities on a document containing a plurality of text lines over a range of angles. A plurality of slope values for a plurality of discrete distances perpendicular to said range of angles is calculated for the plurality of projection profiles. A set of maximum absolute slope values is sorted out from the plurality of slope values. Text lines of first and second type are identified by setting a threshold slope value. Absolute slope values greater than the threshold slope value indicate the plurality of text lines of said first type. Absolute slope values less than the threshold slope value indicate the plurality of text lines of a second type.

    摘要: Methods, machines, and computer-readable media storing machine-readable instructions for segmenting pixels in an image are described. In one aspect, a region of background pixels is identified in the image. At least some of the background pixels in the region are located on a boundary spatially delimiting the region. One or more orientation-dependent adaptive thresholds are determined for one or more respective candidate growth directions from a given background pixel located on the region boundary. Color distances between the given background pixel and candidate pixels in a neighborhood of the given background pixel are determined. The region is grown based on application of the one or more orientation-dependent adaptive thresholds to the determined color distances.

    摘要: A method of resizing documents comprises obtaining a first bitmap document file corresponding to a first size document and identifying, in a single dimensional orientation, at least one whitespace portion between adjacent non-white portions in the first bitmap document file. A size of the at least one whitespace portion in the first bitmap document file in the single dimensional orientation is adjusted to produce a second bitmap document file corresponding to a second size document having a different size than the first size document.
