    • A method identifies the presence of a three-dimensional (3D) image format in received image through the use of feature matching and correspondence. The received image is sampled using a candidate 3D format to generate two sub-images from the received image. Initially, 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, features are detected in the two sub-images and a correspondence is formed between features that match in the two sub-images. Positional differences are computed between corresponding features. The amount and uniformity of the positional differences 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.
    • 一种方法通过使用特征匹配和对应来识别接收图像中三维(3D)图像格式的存在。 使用候选3D格式对接收到的图像进行采样,以从接收到的图像生成两个子图像。 最初,比较这些子图像以确定这些子图像是否与结构相似。 如果子图像不相似,则选择新的3D格式并重复该方法。 如果子图像相似,则在两个子图像中检测到特征,并且在两个子图像中匹配的特征之间形成对应关系。 在相应的特征之间计算位置差异。 然后使用位置差异的数量和均匀性来确定格式是2D还是3D,如果3D,则使用哪种3D格式用于接收的图像。
