High dynamic range video format detection

摘要

A video format detector receives a video signal in a one of a plurality of possible video formats and produces a detected format. A cumulative distribution function generator generates a cumulative distribution function curve from a component of the video signal and a feature detector generates one or more feature vectors from the cumulative distribution function curve. A video classifier accepts the one or more feature vectors from the feature detector and generates a prediction of the video format in which the video signal was produced based, at least in part, on the received feature vectors.
