1. A method for calculating a blur artifact in a motion picture, the motion picture comprising one or more frames defined at a predefined interval of time, each of the one or more frames comprising one or more pixels, the method comprising: detecting edges of the one or more pixels; comparing the detected edges with a first predefined threshold; determining one or more edge pixels, wherein the one or more edge pixels has the edges that exceed the first predefined threshold; determining a set of pixels of the one or more pixels in a set of frames of the one or more frames, wherein the set of pixels is determined in the set of frames, wherein the set of pixels are the one or more pixels that exceed a second predefined threshold, and wherein a set of edge pixels of the one or more edge pixels is determined in the set of pixels; determining one or more blurred edge pixels in the set of edge pixels, wherein the one or more blurred edge pixels are the set of edge pixels for which the edge spread exceeds a third predefined threshold; and calculating the blur artifact as a ratio of a number of the one or more blurred edge pixels and a number of the one or more edge pixels in the set of edge pixels.
