Embodiments are directed towards identifying background pixels in a scanned image so that they can be removed from the image. A histogram of each color channel for an initially scanned portion of the image may be determined. The histogram may represent a frequency distribution of pixels in the scanned portion across each color value for each color channel. A white point tracking profile may be determined based on the histogram. The white point tracking profile may identify a range of color values for each channel that are statistically related to a mode color value of a corresponding color channel. When pixels in the scanned image are determined to have a color profile within the white point tracking profile, then those pixels may be modified to a predetermined color profile, such as a maximum color value for each channel. The modified pixels may then be removed from the scanned image.
