Claim One:
1. A method of locating one or more content portions of an image, the image including a plurality of pixel values, the method comprising automatically performing the following steps using a processor: receiving the plurality of pixel values, the pixel values characterizing the image captured by an imager of a computed-radiography scanner; determining a pixel threshold value using the pixel values so that the pixel threshold value corresponds to a background range of the pixel values by at least determining a histogram of the image, the histogram including pixel values and corresponding pixel counts and slopes; and determining a peak pixel value using the slopes, so that the peak pixel value corresponds to a slope higher in magnitude than a median of magnitudes of the slopes, by at least determining a plurality of peak pixel values using the slopes, so that each peak pixel value corresponds to a slope higher in magnitude than a median of magnitudes of the slopes, and selecting the one of the peak pixel values closest to a background pixel value as the peak pixel value; comparing the determined pixel threshold value to the pixel values so that a background set of the pixel values and a content set of the pixel values are determined; determining a plurality of boundaries between the background and content sets of pixel values; determining the one or more content portions using the determined boundaries; determining respective bounding boxes for the determined one or more content portions; providing a visual indication of at least one of the determined bounding boxes on a display; and extracting image data corresponding to one of the content portions from the image and storing the extracted image data in a tangible, non-transitory computer-readable storage medium.
