Abstract
An apparatus and method for automatically analyzing digital video quality are provided. The apparatus for automatically analyzing digital video quality includes a video analyzing unit and a result displaying unit. The video analyzing unit analyzes a texture attribute of an input video and analyzes a color attribute of the input video, thereby obtaining a texture attribute analysis result and a color attribute analysis result. The result displaying unit determines whether a reference video for video quality analysis exists or not. When the reference video exists, the result displaying unit determines the texture attribute analysis result as a main component analysis result and the color attribute analysis result as a minor component analysis result, respectively, and displays the determined analysis results on a screen in a form of numerical values and graphs together with the input video. On the contrary, when the reference video does not exist, the result displaying unit determines the texture attribute analysis result as the minor component analysis result and the color attribute analysis result as the major component analysis result, respectively, and displays the determined ana…
