Abstract
Method and apparatus for detecting source-based artifacts in a compressed video data set formed by outputting a baseband video data set from a source device and applying a codec algorithm thereto to generate the compressed video data set. In some embodiments, the compressed video data set is decompressed to provide a decoded video data set, and at least one source-based artifact in the decoded video set is detected responsive to a luminance value of at least one pixel in the decoded video data set, the at least one source-based artifact induced by the source prior to the compression encoding of the input video frame and detected independently of the input video frame.
