摘要
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 one or more sensors; combining the image data with timing information into a coherent signal by a processor; estimating periodic and aperiodic components of the coherent signal using least squares estimation by the processor, wherein the periodic component represents a banding profile; and wherein at least the periodic component is used to generate an output.
