This repository holds the models and solutions developed by Pablo Barros based on emotion recognition and learning.

The KEF framework was developed to facilitate the planing and fast prototyping of different scientific experiments. All the examples in this repository use the KEF framework.


tensorflow, keras, matplotlib, h5py, opencv-python, librosa, pillow, imgaug, python_speech_features, hyperas

If you want to run on a GPU, install tensorflow-gpu instead of tensorflow


Each of the examples here run within the KEF framework. Also, each example needs a specific dataset which is not available here. All the demos and examples here run on Python 2.7.

Hand gesture recognition

  • Multichannel Convolution Neural Network for hand posture recognition using the NCD dataset (Barros et al., 2014)

Auditory emotion recognition

  • Audio Channel for the OMG-Emotion dataset (Barros et al., 2018)
  • Audio Channel for the RAVDESS dataset (Barros et al., 2018)

Visual emotion recognition

  • Face Channel for the OMG-Emotion dataset (Barros et al., 2018)
  • Face Channel for the FERPlus dataset (Barros et al., 2018)

Crossmodal emotion recognition

  • Cross Channel for the OMG-Emotion dataset (Barros et al., 2018)
  • Cross Channel for the RAVDESS dataset (Barros et al., 2018)

Trained Models

Each of the examples has a pre-trained model associated with it. Please refer to the TrainedModels folder.

Ready-to-Run Demos


Follows the links for different corpora that I developed or was involved on the development. Most of the examples here make use of these corpora:
