The current document is directed to methods and systems that straighten in the text lines of text-containing digital images. Initial processing of a text-containing image identifies the outline of a text-containing page. Next, aggregations of symbols, including words and word fragments, are identified within the outlined page image. The centroids and inclination angles of the symbol aggregations are determined, allowing each symbol aggregation to be circumscribed by a closest-fitting rectangle oriented in conformance with the inclination angle determined for the circumscribed symbol aggregation. A model is constructed for the text-line curvature within the text image based on the circumscribed symbol aggregations and is refined using additional information extracted from the text image. The model, essentially an inclination-angle map, allows for assigning local displacements to pixels within the page image which are then used to straighten the text lines in the text image.
An image-processing subsystem included within a device, appliance, or system that acquires an image containing text with curved text lines and inputs the acquired, text-containing image to the image-processing subsystem to generate a corresponding corrected image in which the text lines are straightened and have a rectilinear organization, the image-processing subsystem comprising:
A method carried out by an image-processing subsystem included within a device, appliance, or system that acquires an image containing text with curved text lines and inputs the acquired, text-containing image to the image-processing subsystem to generate a corresponding corrected image in which the text lines are straightened and have a rectilinear organization, the method comprising:
A physical data-storage device that stores computer instructions that, when executed by one or more processors of a hardware layer of an image-processing subsystem that includes one or more processors and one or more memories and that is included within a device, appliance, or system that acquires an image containing text with curved text lines to receive the acquired, text-containing image from the device, appliance, or system and generate a corresponding corrected image in which the text lines are straightened and have a rectilinear organization by:
