Call for Participation / Papers 2nd International Audio/Visual Emotion Challenge and Workshop (AVEC 2012) in conjunction with ACM ICMI 2012, October 22-26, Santa Monica, California, USA Register and download data and features: _____________________________________________________________ Scope The Audio/Visual Emotion Challenge and Workshop (AVEC 2012) will be the second competition event aimed at comparison of multimedia processing and machine learning methods for automatic audio, visual and audiovisual emotion analysis, with all participants competing under strictly the same conditions. The goal of the Challenge is to provide a common benchmark test set for individual multimodal information processing and to bring together the audio and video emotion recognition communities, to compare the relative merits of the two approaches to emotion recognition under well-defined and strictly comparable conditions and establish to what extent fusion of the approaches is possible and beneficial. A second motivation is the need to advance emotion recognition systems to be able to deal with naturalistic behavior in large volumes of un-segmented, non-prototypical and non-preselected data as this is exactly the type of data that both multimedia retrieval and human-machine/human-robot communication interfaces have to face in the real world. We are calling for teams to participate in emotion recognition from acoustic audio analysis, linguistic audio analysis, video analysis, or any combination of these. As benchmarking database the SEMAINE database of naturalistic video and audio of human-agent interactions, along with labels for four affect dimensions will be used. Emotion will have to be recognized in terms of continuous time, continuous valued dimensional affect in the dimensions arousal, expectation, power and valence. Two Sub-Challenges are addressed: The Word-Level Sub-Challenge requires participants to predict the level of affect at word-level and only when the user is speaking. The Fully Continuous Sub-Challenge involves fully continuous affect recognition, where the level of affect has to be predicted for every moment of the recording. Besides participation in the Challenge we are calling for papers addressing the overall topics of this workshop, in particular works that address the differences between audio and video processing of emotive data, and the issues concerning combined audio-visual emotion recognition Topics include, but are not limited to: Audio/Visual Emotion Recognition: . Audio-based Emotion Recognition . Linguistics-based Emotion Recognition . Video-based Emotion Recognition . Social Signals in Emotion Recognition . Multi-task learning of Multiple Dimensions . Novel Fusion Techniques as by Prediction . Cross-corpus Feature Relevance . Agglomeration of Learning Data . Semi- and Unsupervised Learning . Synthesized Training Material . Context in Audio/Visual Emotion Recognition . Multiple Rater Ambiguity Application: . Multimedia Coding and Retrieval . Usability of Audio/Visual Emotion Recognition .
