How would you analyze a video clip to determine if it was

  shot by an amateur or a professional?

Interview Answer

1 Answer


An amateur most likely does not have a steady hand. You can compare consecutive timeframes, analyzing the difference between images. This probably needs to be done globally, since a movie scene of an explosion would also satisfy this property locally in time. You could develop a series of measures of difference between two frames, compute the average and standard deviation for each measure, and make a classifier (SVM?)
