Abstract: Methods and apparatus for detecting a repetitive pattern in a sequence of audio frames are described. Similarity values of a first similarity matrix with first resolution for the sequence are calculated. An adaptive threshold is estimated from the similarity values for classifying the similarity values into repetition or non-repetition. For each of one or more offsets of a second similarity matrix with second resolution higher that the first resolution, similarity values of the second similarity matrix corresponding to the offset are calculated. Then the calculated similarity values are binarized with the adaptive threshold to obtain binarized data. Finally, the repetitive pattern is detected from the binarized data. The requirement on memory may be reduced because less data are stored in detecting the repetitive pattern.

Abstract: Disclosed is a people counter including a setting interface and a setting method thereof. Since a reference width used to count of a moving object within an image is visibly arranged and displayed on a screen so that a detected width of the moving object can be compared with the reference width, setting and verification for count is very easy. In addition, since the interface can be freely moved for adjustment and comparison of a reference width using a pointing device such as a mouse, thereby providing verification and resetting which are intuitive and practical over conventional manual adjustment schemes, count accuracy can be easily increased in different environments depending on conditions or type of moving objects within an image.

Abstract: Multiple private advertising systems independently profile users while protecting user privacy and enabling content publishers to limit advertiser access to their content and user information. A client computer supports private profiling modules, each of which is associated with a different advertising network and is adapted to create a user profile based on the content accessed by the user. Content publishers specify profiling restrictions to limit access by private profiling modules to profiling information associated with their content. The profiling restrictions and profiling information may be included in the content or communicated separately to the client computer. Profiling restrictions and profiling information may be expressed in a markup language. Each private profiling module selects information items of interest to the user based on the user profile that it creates.
