Facial Expression Recognition with LBP and ORB Features

Abstract: Emotion plays an important role in communication. For human–computer interaction, facial expression recognition has become an indispensable part. Recently, deep neural networks (DNNs) are widely used in this field and they overcome the limitations of conventional approaches. However, application of DNNs is very limited due to excessive hardware specifications requirement. Considering low hardware specifications used in real-life conditions, to gain better results without DNNs, in this paper, we propose an algo… Show more

“…Appearance-based methods are the use of features obtained from image processing techniques and calculations on pixel values. Methods such as Local Binary Patterns (LBP) [22][23][24], Histogram of Oriented Gradients (HOG) [25], Gabor Filters [26,27], Local Phase Quantization (LPQ) [28], Scale-Invariant Feature Transform (SIFT) [29,30] [31].…”

Local Binary Pattern (LBP) and Oriented Fast and Rotated Brief (ORB) are combined as one of the feature descriptor to recognize facial expressions in (8) . The study in (8) (9) for emotion recognition with an average recognition rates of 94.75% and 96.86%, JAFFE and CK+ respectively.…”
