1. A video processing method for a three-dimensional (3D) display based on a multi-cue process, the method comprising: acquiring a cut boundary of a shot by performing a shot boundary detection with respect to each frame of an input video; computing, by a processor, a texture saliency with respect to each pixel of the input video; computing, by the processor, a motion saliency with respect to each pixel of the input video; computing, by the processor, an object saliency with respect to each pixel of the input video based on the acquired cut boundary of the shot; and acquiring, by the processor, a universal saliency with respect to each pixel of the input video by combining the texture saliency, the motion saliency, and the object saliency, wherein the acquiring of the universal saliency comprises computing the universal saliency with respect to a pixel x by combining the texture saliency, the motion saliency, and the object saliency based on Equation 3, and wherein Equation 3 corresponds to 
 S(x)=W T ·S T (x)+W M ·S M (x)+W O ·S O (x), where S T (x) denotes the texture saliency of the pixel x, S M (x) denotes the motion saliency of the pixel x, S O (x) denotes the object saliency of the pixel x, W T denotes a weight variable of the texture saliency, W M denotes a weight variable of the motion saliency, and W O denotes a weight variable of the object saliency.
