Latest trends in emotion recognition methods: case study on emotiw challenge

Emotion recognition is becoming increasingly very active field in research. In recent past, this research field has emerged as a milestone in software engineering, website customization, education, and gaming. Moreover, Emotion recognition models are used by more and more intelligent system to improve the multimodal interaction. Therefore, this paper demonstrates the recent literature on the emotion recognition methods presented at Emotion Recognition in the Wild (EmotiW) challenge. EmotiW is a grand challenge organized every year in ACM international conference on multimodal interaction. There has been number of methods presented every year at EmotiW for emotion analysis which are incorporated in this paper on the basis of emotion categorization in different areas. This work depicts a broad methodical analysis of EmotiW challenge for sentiments analysis which can help researchers, IT professionals and academia to find worthy technique for emotion grouping in several areas. It would also provide aid to select the most suitable technique for emotion recognition on the basis of their applications.
