摘要： Techniques are described in which an image capture device captures image data from web material. The image data comprises pixel values for the cross-web field of view of the image capture device. An analysis computer includes a computer-readable medium that stores parameters for a plurality of different normalization algorithms to normalize a cross-web background signal for the image capture device to a common desired value. The computer-readable medium further stores coefficients specifying a weighting for each of the plurality of normalization algorithms. The analysis computer computes a normalized value for each of the pixels of the image data as a weighted summation of results from application of at least two of the pixel normalization algorithms using the stored parameters.
