Intelligent System To Help Autistic Children Recognize Emotions
Computer scientists working towards a portable facial expression recognizer
Computer scientists from Nanyang Technological University in Singapore are working on the development of an efficient and intelligent facial expression recognition system. The system is capable of locating the face region using derivative-based filtering and recognizing facial expressions using boosting classifier. The portable device is being developed to help autistic children understand the emotions of surrounding people. A paper detailing the specifics of the device will be published in the journal Intelligent Decision Technologies (Volume 3:3).
The portable facial expression recognizer locates the edge of the human face through Gaussian derivatives, Laplacian derivatives and filter out non-face images using Adaboost. Secondly, the feature locator finds crucial fiducial points for subsequent feature extraction and selection processing. Finally, the meaningful features are classified into the corresponding classes.
