Abstract: After a digital content is loaded into an information terminal such as a PC, ID information unique to a viewer or a user of the PC is imprinted into the content. The ID information is imprinted into a predetermined location of the content or alternatively, it may be imprinted over the entire content in the form of a spatial frequency. The content with an ID added thereto is then enabled to be used in the terminal.

Abstract translation: 在将数字内容加载到诸如PC的信息终端之后，将观看者或PC的用户唯一的ID信息印刷到内容中。 ID信息被印记到内容的预定位置，或者可以以空间频率的形式印在整个内容上。 然后，可以在终端中使用附加了ID的内容。

Abstract: A multiresolutional filter called a critical point filter is introduced. This filter extracts a maximum, a minimum, and two types of saddle points of pixel intensity for every 2null2 (horizontalnullvertical) pixels so that an image of a lower level of resolution is newly generated for every type of a critical point. Using this multiresolutional filter, a source image and a destination image are hierarchized, and source hierarchical images and destination hierarchical images are matched using image characteristics recognized through a filtering operation.
