Patent ID: 6996290

Claim:
A method for binding curvature correction, comprising: electronically acquiring an image of a set of pages of a bound medium, the image of the set of pages having a binding curvature distortion; generating a corrected image, the corrected image including the content of the image without the binding curvature distortion; and wherein the generating of the corrected image further comprises: determining a three dimensional model of the pages in the image; and mapping each of the pages to the corrected image using the three dimensional model, wherein the corrected image is expressed in two dimensions; and wherein the determining of the three dimensional model of the pages in the image further comprises: obtaining a number of input variables representative of characteristics of the image; and applying the number of input variables to inputs of at least one neural network to generate a number of coefficients of a surface equation representing the three dimensional model; and wherein the obtaining of the number of input variables representative of characteristics of the image further comprises obtaining a number of values that are representative of a corresponding number of measurements of a brightness gradient in the binding curvature distortion.
