    摘要： A method for image processing includes obtaining a mask of a stroke from an image and identifying a plurality of cross edges for the stroke based on the mask and a reference line. The plurality of cross edges includes a group of adjacent cross edges that intersect the reference line. The method further includes (a) calculating a first vector based on positions of at least two of the cross edges in the group, (b) expanding the group, based on the first vector, to include cross edges adjacent to the group that do not intersect the reference line, (c) calculating a second vector based on positions of at least two of the cross edges in the expanded group, and (d) expanding the expanded group, based on the second vector, to include a second group of adjacent cross edges nearby the expanded group that do not intersect the reference line.

    摘要： A method for image processing, including: obtaining an image including a table; identifying a first line corresponding to the table in the image, a first confidence value for the first line, and a first angle for the first line; initiating a plurality of angle bins corresponding to multiple angles; calculating, based on the first confidence value, a first plurality of bin values for a first subset of the plurality of angle bins within a window surrounding the first angle; adding the first plurality of bin values to the first subset of the plurality of angle bins; identifying an angle bin of the plurality of angle bins having a maximum bin value; and rotating the image based on the angle bin having the maximum bin value.

    摘要： A method and image processing system for removing a visual object from an image, e.g., a moving image, is described. An image is provided in which a visual object to be removed is selected, for which a mask is determined. Pixels outside the mask that are intended to be used for replacing pixels inside the mask are selected, based on a similarity measure, comprising an appearance similarity measure representing the visual similarity between a previously selected pixel for replacing the pixel to be replaced and the pixel to be selected, and a geometry similarity measure, representing the closeness of the pixel to be selected to the pixel among the pixels outside the mask that was previously used for replacing the pixel adjacent to the pixel to be replaced. The pixels inside the mask are replaced by copying the properties of the selected pixels to the respective pixels to be replaced.

    摘要： A device detects multi-spectral imaging by using scan elements. The device may include an illumination module and a detection module to detect light scattered from an object illuminated by the illumination module. The device may also include an array of light sources to produce light at a plurality of different wavelengths, and create a line of illumination with each of the different wavelengths. The light detection may be applied to authenticate and validate documents, such as banknotes moving along a document conveyer.
