In this condition autistic people are not able to do social communication. The autistic people have rigid and repetitive behaviors.People with autism have difficulty in recognition of emotions. This study works on emotion detection of autistic children from facial expression. This study works on happiness, angry, disgust and neutral emotions. With image processing and machine learning algorithms proved that the detection of emotion of autistic children can be possible. This study implements Local Binary Pattern to extract features from images and uses machine learning algorithm for training and testing of emotions. It implements Support Vector Machine algorithm for classify the emotions.
