EMS: Expression based Mood Sharing for Social Networks MdMunirulHaque Mohammad Adibuzzaman Department of Mathematics, Statistics, and Computer ScienceMarquette University
Outline • Motivation • State of the art • Classification of models • FACS • Drawbacks • Comparison • Open issues • System Overview • System Architecture • Implementation
Motivation • Facebook has 500 million active users • twitter has 190 million visitors per month • Number of smart phone users has crossed 45 millions • Many mood applications in FB • My Mood • SpongeBob Mood • The Mood Weather Report • Name and Mood Analyzer • Manual setting
State of the Art • Active Appearance Model (AAM) • Computer Expression Recognition Tool (CERT) • Eigenface, Eigeneye, Eigenlips • Artificial Neural Network (ANN) • Relevance Vector Machine (RVM)
Drawbacks • Reliability on clear frontal image • Out-of-plane head rotation • Right feature selection • Fail to use temporal and dynamic information • Considerable amount of manual interaction • Noise, illumination, glass, facial hair, skin color issues • Computational cost • Mobility • Intensity • Reliability.
Eigenface, Eigeneye, Eigenlips Eigenfaces for the training image set
Characteristics • Real Time Mood to Social Media • Location Aware Sharing • Mood Aware Sharing • Mobility • Resources of Behavioral Research • Context Aware Event Manager
Open Issues • Deception of Expression (suppression, amplification, simulation) • Difference in Cultural, Racial, and Sexual Perception • Intensity • Dynamic Features
System Architecture Apache Tomcat Container Application Server MATLAB Builder JA MATLAB AXIS2 JAVA Library runs on MCR Expression Detection Script SOAP/Web Service Engine Server HTTP Call WAMP Browser/Mobile PHP Web Server Client FIG: Expression Detection Architecture
Future Work • Build a Facebook application which will capture the user image using device camera(webcam or mobile camera). • Feed that image to the MATLAB Script and get Expression detected. • Do a survey on the user response of the Facebook application • Increase accuracy • Images- not present in the database • Confusion matrix
Conclusion • Most computational research requires the extensive ability of MATLAB for different computations like image processing, forecasting and other areas. • Using web service to run a MATLAB script will help do research on Computational sciences research.
