An apparatus and method of the present disclosure provides an automatic banding region detection function for detecting an image region that has a smooth linear transition of color intensity and is prone to have banding artifacts in image processing. The apparatus and method use a parametric model based approach to detect the banding region. The apparatus and method provide for segmenting at least one first image into at least one homogeneous color region (304), estimating the linear transition of color intensity for the at least one homogeneous color region (308), and if the linear transition of color intensity is substantially smooth, classifying the at least one homogenous color region as a banding region (310).
