Video-genre classification

Method for classifying a video sequence (VS), characterized by

• analyzing the video sequence using a plurality of genre-specific detector modules (M1-M5), each genre-specific detector module providing a probability value (P1-P5) indicating the probability that the video sequence belongs to the genre assigned to the genre-specific detector module;
• and
• analyzing the probability values of the plurality of genre-specific detector modules using a combiner (CM) which analyzes said probability values and generates a classification signal (SC) classifying the video sequence as belonging to a specific genre (g);
• wherein the probability values of the plurality of genre-specific detector modules are analyzed by a first evaluating unit (EU1) of said combiner, said first evaluating unit providing a first probability vector (V1) comprising for each genre a first probability value indicating the probability that the video sequence belongs to the respective genre, and a first preliminary decision (PD1) indicating which genre the video sequence presumably belongs to,
• the probability values of the plurality of genre-specific detector modules are further analyzed by a second evaluating unit (EU2) of said combiner, said second evaluating unit providing a second probability vector (V2) indicating for each genre a second probability value indicating the probability that the video sequence belongs to the respective genre, and a second preliminary decision (PD2) indicating which genre the video sequence presumably belongs to, wherein the first evaluating unit and the second evaluating unit differ in their analyzing algorithm;
• and
• said classification signal is generated based on an evaluation of said first and second preliminary decisions.
