Micro-attention for micro-expression recognition [PDF]

Neurocomputing, 2020
Micro-expression, for its high objectivity in emotion detection, has emerged to be a promising modality in affective computing. Recently, deep learning methods have been successfully introduced into the micro-expression recognition area. Whilst the higher recognition accuracy achieved, substantial challenges in micro-expression recognition remain.

Domain Regeneration for Cross-Database Micro-Expression Recognition [PDF]

IEEE Transactions on Image Processing, 2018
Recently, micro-expression recognition has attracted lots of researchers' attention due to its potential value in many practical applications, e.g., lie detection. In this paper, we investigate an interesting and challenging problem in micro-expression recognition, i.e., cross-database micro-expression recognition, in which the training and testing ...

OFF-ApexNet on micro-expression recognition system [PDF]

Signal Processing: Image Communication, 2019
When a person attempts to conceal an emotion, the genuine emotion is manifest as a micro-expression. Exploration of automatic facial micro-expression recognition systems is relatively new in the computer vision domain. This is due to the difficulty in implementing optimal feature extraction methods to cope with the subtlety and brief motion ...
