A method, system, and computer program product for estimating a banding profile in an image printing system is disclosed. The method includes obtaining image data across multiple measurement intervals by a sensor; combining the image data with timing information into a coherent signal by a processor; determining aperiodic components of the coherent signal by the processor; determining the periodic component of the coherent signal using spline interpolation, wherein the periodic component represents a banding profile, by the processor; and printing an output print with a correction applied based on the banding profile. |
