Zero-Shot Audio-Visual Compound Expression Recognition Method based on Emotion Probability Fusion

Abstract

A Compound Expression Recognition (CER) as a part of affective computing is a novel task in intelligent human-computer interaction and multimodal user interfaces. We propose a novel audio-visual method for CER. Our method relies on emotion recognition models that fuse modalities at the emotion probability level, while decisions regarding the prediction of compound expressions are based on the pair-wise sum of weighted emotion probability distributions. Notably, our method does not use any training data specific to the target task. Thus, the problem is a zero-shot classification task. The method is evaluated in multi-corpus training and cross-corpus validation setups. We achieved F1-score values equal to 32.15% and 25.56% for the AffWild2 and C-EXPR-DB test subsets without training on target corpus and target task, respectively. Therefore, our method is on par with methods developed training target corpus or target task.

Quick Start

This repository introduces a new zero-short audio-visual method for compound expression recognition.

Model weights are available at models. You should download them and place them in src/weights. You will also need weights for the RetinaFace detection model. Please refer to the original repository.

To predict compound expression by a video, you should run the command:

python run.py --path_video <your path to a video file> --path_save <your path to save results>

Example of predictions obtained by static visual (VS), dynamic visual (VD), audio (A), and audio-visual (AV) models:
