This paper presents an algorithm for designing a system that classifies standard
human facial expressions which are fear, disgust, sad , surprise, anger, happiness, and the
normal expression . The facial expression that is presented in the input im
age of the system
can be classified depending on extracting appearance features then, it is entered into
neural network to complete the classification process using Matlab as a programming
language.
Multiple stages completed the work, which are, (collection images, pre-processing of
the images, feature extraction, training neural network, classification and testing). Our
system has been able to achieve the highest rating when the expression of anger reached
100 %, while the lowest rating was at the expression of sad by 30%.
The aim of the work is to improve the performance of the WLD
descriptor using Gabor filters in a preprocessing stage. The
performance of the improved descriptor will be compared with the
performance of the LBP descriptor(a widely used descriptor i
n FER
researches). This performance will be achieved using the extremely
used expert system SVM besides the expert systems CSD and MLP.
