This paper puts forward a novel two-steps algorithm to search and detect advertisement signal quickly through broadcast audio signal. It is an improved method based on the Fast Commercial Detection method. The original method takes fixed shift step, and does not take random starting positions of advertisement into account, which may influence the similarity. The modified algorithm in this paper solves...
This paper presents an audio indexing system to search for known advertisements in radio broadcast streams, using automatically acquired segmental units. These units, called Automatic Language Independent Speech Processing (ALISP) units, are acquired using temporal decomposition and vector quantization and modeled by Hidden Markov Models (HMMs). To detect commercials, ALISP transcriptions of reference...
W artykule przedstawiono sposób tworzenia klasyfikatorów, które mają posłużyć do wykrywania reklam w obrazach na stronach WWW. Opisano postać i rodzaj danych, jakie zostały wykorzystane do wytworzenia modeli. Omówiono wszystkie etapy tego procesu tworzenia modelu, na który składają się filtracja dostępnych danych, dobór odpowiednich zmiennych, ocena utworzonych klasyfikatorów.
This paper presents the first method for detecting advertisements in digitized press. The system aims at locating and recognizing ads. A color segmentation approach which is robust against digitization noise is introduced. The color separation output is used to carry out layout segmentation in document pages and to compute visual features. Block classification results, given with a variety of magazine...
There is a number of automated shot-change detection methods for indexing a video sequence to facilitate browsing and retrieval have been proposed in recent years. In this paper, shot change (hard cut) detection that is based on "inter-frame difference" and its comparison with a threshold are discussed. The summery of changing video threshold on hard cut detection is done. A threshold value...
Advertisement detection in a TV video recording/archiving system is a challenging task. In this paper, shot change (hard cut) detection that is based on ??inter-frame difference??, ??normalized difference energy?? and the ??normalized sum of absolute differences?? and its comparison with a threshold are discussed. The effects of changing video threshold on hard cut detection have been summarized....
In this paper, we propose a method for detecting and precisely segmenting repeated sections of broadcast streams. This method allows advertisements to be removed and replaced with new ads in redistributed television material. The detection stage starts from acoustic matches and validates the hypothesized matches using the visual channel. Finally, the precise segmentation uses fine-grain acoustic match...
A new technique provides accurate, efficient ad detection for online TV rebroadcasts. As online television grows in popularity, providers are seeking cost-effective ways to replace original advertisements in rebroadcasts with new ads that are not only fresher but that can target individual viewers' interests and preferences. Alternatively, completely removing commercials might be desirable for subscribers...
