Imagine a machine that can laugh and cry, learn and dream, and can express its inner responses to how it perceives you to feel. We have been working on a visual modelling methodology for the construction, visualisation and animation of neural systems called Brain Language [BL] — a novel simulation environment for neural models. We are developing the technology to simulate faces both inside and out. It can express itself in a natural manner but also allows you to visualise the mental imagery emerging in its mind. We model the brain processes which give rise to behaviour and social learning and use these to animate lifelike models of the face that can interact with you. The methodology allows creations of animations and real-time visualisations from biologically based neural network models, allowing simulation effects to be viewed in an interactive context. Show Truncated Breadcrumbs. We simulate how faces move and how they look, and even their underlying anatomic structure. Facial tracking and analysis We are developing computer vision-based systems to track and analyse facial expression and state-of-the-art algorithms for individual facial muscle activation.
