A method identifies the presence of a three-dimensional (3D) image format in received image through the use of image difference determination. The received image is sampled using a candidate 3D format to generate two sub-images from the received image. When the candidate 3D format is a non-blended 3D format, these sub-images are compared to determine whether these sub-images are similar with respect to structure. If the sub-images are not similar, a new 3D format is selected and the method is repeated. If the sub-images are similar, an image difference is computed between the two sub-images to form an edge map. Thicknesses are computed for the edges in the edge map. The thickness and uniformity distribution of the edges are then used to determine whether the format is 2D or 3D and, if 3D, which of the 3D formats was used for the received image. |
