Technology Overview

A method of detecting forged video, using Chroma key background, in particular, is described. The method includes dividing the sequence of image frames into image blocks and extracting blurring artefact from each image block using wiener deconvolution of low pass filter. The blurring correlation of blurring artefact between intermediate image block is then determined to find background and foreground information. A histogram of correlations showing background and foreground information is built. Chroma key background is determined from the histogram of correlations.
