1. A method for scene change detection, the method comprising: accessing a first video signal ( 102 ) and a second video signal ( 112 ), wherein both the first video signal and the second video signal represent the same video content but at a different color grade; for a sequence of consecutive frames in the first and second video signals: computing ( 310 ) prediction coefficients for a prediction model to generate predicted frames of the first video signal given data of the second video signal; computing ( 315 ) prediction errors signals between the generated predicted frames and the corresponding frames of the first input signal; and determining ( 320 ) a scene change in the sequence of the consecutive frames ( 320 ) based on the prediction error signals.
