Abstract: A method for segmenting a digital image into a foreground region and a key color region including characterizing a distribution of key color values; using the distribution of key color values to produce a multi-dimensional look-up-table having three or more dimensions indexed by color values in a selected color space to define a key color volume; addressing the multi-dimensional look-up table with color values of pixels in the digital image to determine whether the color values of such pixels are within the key color volume; and labeling pixels in the digital image whose color values fall within the key color volume to be within the key color region and labeling all other pixels to be within the foreground region whereby the digital image is segmented into the foreground region and the key color region.

Abstract: A method is disclosed for calibrating a digital printer to provide a substantially aim printer response. A test target is processed through a set of potential calibration functions to form a set of processed test targets and the set of processed test targets is printed using the digital printer. Thereafter, the printer response for each of the potential calibration functions is evaluated by visually examining the printed set of processed test targets. The potential calibration function that best matches a visual criterion is then selected.
