Abstract

A method, an image processing apparatus, and a non-transitory computer readable storage medium encoded with software for residual row noise removal in digital images are provided. The residual row noise is removed by dividing color plane images into vertical stripes and for each vertical stripe masking out the stripe pixels, determining a row means profile, determining a smoothed row means profile, determining row offset values for each of the horizontal stripe rows, determining corrected row offset values for horizontal stripe rows based on corresponding row offset values of adjacent vertical stripes and subtracting the corrected row offset value from the stripe pixel values.
