Abstract— -Emotions are an incredibly important aspect of human life and basic research on emotions of the past few decades has produced several discoveries that have led to important real world applications.Facial expression analysis deals with the recognition of emotions from the face expressions in the image. Children with mental retardation find difficulty in emotion recognition. In this method, the emotion of the mentally retarded children is recognized using MATLAB. The expressions includes happy, sad and neutral. It is employed in seven subjects with mild mental retardation. The test and train set of images are obtained from the subjects. The facial features are obtained from the low dimensional test and train images using principal component analysis (PCA). The emotions are recognized from the Euclidean distance of the extracted features calculated between the test and train images < final year projects >
