Abstract
A system and method for identifying presence of digital ghosting artifacts in videos is disclosed. The method comprises estimating a blending parameter (α) for a current image using a previous image and a next image of a digital video stream. Successively, a blended image (B) is created by mixing contents of the previous image and the next image based on the estimated blending parameter (α). Thereafter, a first similarity is computed between the blended image (B) and a de-interlaced image (C), based on a Normalized Cross Correlation (NCC) between multiple blocks of the blended image (B) and the de-interlaced image (C). Successively, a second similarity is computed between the blended image (B) and the de-interlaced image (C), based on values of standard deviation of an absolute difference frame determined between the blended image (B) and the de-interlaced image (C). The de-interlaced image (C) is finally identified to comprise digital ghosting artifact based on values of the first similarity and the second similarity.
