Abstract: A method of producing a mask for digital unsharp masking or for digital equalization and a computer readable memory having recorded thereon statements and instructions for execution on a computer for carrying out the method both comprise: receiving an unprocessed digital radiograph; creating a first new image that is a copy of the radiograph; then creating a second new image by blurring the first new image with a kernel of a selected starting kernel size.

Abstract: A method for balancing areas of varying density within a digital image, and a computer readable storage medium encoded with the method comprise determining a pixel enhanced intensity value by dividing a pixel unequalized intensity value by a pixel mask intensity value, then scaling the dividend by an exposure compensation factor. The unequalized intensity value is from an unequalized digital image recorded by a digital imaging device. The pixel mask intensity value is proportional to the pixel's blurred intensity value. The exposure compensation factor is selectable by the user and is typically selected as the mean blurred intensity of the pixels.

Abstract: The present invention is directed generally to correcting geometric distortion in a digitally captured image. The method involves receiving an uncorrected digital image of a phantom having a plurality of fiduciary marks; locating an uncorrected digital position for each of the fiduciary marks; mapping the uncorrected digital position to a corrected digital position for each fiduciary mark; and interpolating or extrapolating the fiduciary mark map to all pixels in the uncorrected digital image, thereby creating a correction map for uncorrected digital images.
