Mood Dependent Art

It is always nice to see novel combinations of research areas that produce innovative applications. Recently, researchers from the Universities of Boston, USA and Bath, UK have developed such a system called "Empathic Painting: Interactive stylization using observed emotional state." From a Computer Vision perspective, the work includes facial expression recognition. Also, Image Processing and graphics are used to create a real-time painting filter. While these areas are not ground-breaking by themselves, together they make a very unique and creative use of technology.
