Literature Survey on Emotion Recognition for Social Signal Processing

摘要

Emotion is a significant aspect o the progress of human-computer interaction systems. To achieve best functionality through HCI, the computer is able to understand the emotions of human effectively. To do so, there is a need for designing an effective emotion recognition system by using the social behavior of human beings into the account. The signals through which human being tries to express the emotions are called as social signals, and the examples are facial expression, speech, and gestures. A vast research is carried out in earlier to achieve effective results in the emotion recognition system through social signal processing. This paper outlines the details of earlier developed approaches based on this aspect. Since there are number of social signals, the complete survey is categorized as audio-based and image-based. A further classification is based on the modality of input, i.e., single modal (single social signal) or multimodal (multiple social signals). Based on the methodology accomplished to achieve the objectives, this survey is further classified into different classes and details are provided more clearly. Brief details about the databases involved in the accomplishment are also explained clearly.
