Shweta Malwatkar, Rekha Sugandhi, Anjali R.
2017 International Journal of Computer Applications  
This paper also presents some basic classifiers such as SVM, ANN, KNN and HMM, used for emotion classification and audiovisual databases with their emotion categories.  ...  Such emotion recognition system involves three main steps: face detection, feature extraction and facial expression classification.  ...  Now for actual affect recognition, test video is provided as input. Again for this test video, concept map is generated. This concept map of test video is classified against trained concept map.  ...

Hierarchical Attention-Based Multimodal Fusion Network for Video Emotion Recognition

Xiaodong Liu, Songyang Li, Miao Wang, Qiangqiang Yuan
2021 Computational Intelligence and Neuroscience  
The context, such as scenes and objects, plays an important role in video emotion recognition. The emotion recognition accuracy can be further improved when the context information is incorporated.  ...  To address the problem of emotion difference between different modes and different images, this paper proposes a hierarchical attention-based multimodal fusion network for video emotion recognition, which  ...  [27] conduct concept selection to investigate the relations between high-level concept features and emotions. e discriminative concepts play important roles in emotion recognition.  ...

Context-Aware Attention Network for Human Emotion Recognition in Video

Xiaodong Liu, Miao Wang, Constantine Kotropoulos
2020 Advances in Multimedia  
In this paper, we first build a video dataset with seven categories of human emotion, named human emotion in the video (HEIV).  ...  Recognition of human emotion from facial expression is affected by distortions of pictorial quality and facial pose, which is often ignored by traditional video emotion recognition methods.  ...  When we show a video with a person marked, we ask the annotators to select one of the emotion categories that suit that video.  ...

The Effect of the Number of Key-Frames on the Facial Emotion Recognition Accuracy

Suhaila N. Mohammed, Alia K. Abdul Hassan
2021 Engineering and Technology Journal  
Dynamic and static information is employed to select the most effective key-frames of the facial video with a short response time.  ...  The selected keyframes are then fed to a graph mining-based facial emotion recognition system to select the most effective sub-graphs in the given set of keyframes.  ...  In realworld environments, for example, the detection of the emotion from a video with different talking faces poses great challenges on facial emotion recognition [3] .  ...
