    摘要: A method for processing scanned image data, executed at least in part by a computer system, obtains scanned image data, obtains a predetermined image quality profile that has one or more image quality requirement values, and generates processed image data by applying one or more image processing operations to the image data in accordance with a processing script. The method calculates image quality metrics from the processed image data and compares the calculated image quality metrics to the one or more image quality requirement values from the predetermined quality profile. Results of the image quality comparison are displayed.

    摘要: A method for calculating a skew angle of an original image, executed at least in part on a computer system stores image data for the original image in an electronic memory, then forms an energy-normalized image according to the relative contrast amplitude of image features over each of a plurality of local image regions within the stored image data. A partitioned image is formed by partitioning the energy-normalized image into a number of sub-regions. A summed region is formed as a combination of image pixel data from the sub-regions. A Fourier magnitude spectrum is obtained by performing a Fourier transform on the summed region. The skew angle is calculated according to the peak value of a radial line integration function that is formed by integrating the Fourier magnitude spectrum along each of a plurality of lines of constant radial angles. An output signal indicates the calculated skew angle.
