Signal processing for computational photography and displays [from the guest editors]

The articles in this special issue focus on the topic of computational photography and displays. Advances in imaging and displays have been the source of numerous scientific breakthroughs, as evidenced by the more than ten Nobel Prizes awarded for various inventions and discoveries in the imaging sciences. Over the last decade, imaging and displays have completely conquered our imagination, with mind-numbing statistics like more than a billion cameras being sold every year, more than a trillion photos taken each year, more than 200,000 images uploaded to Facebook alone every minute, and so on. In addition, interest and excitement around three-dimensional (3-D) displays, augmented reality displays, and virtual reality displays have grown exponentially over the last decade. This revolution in consumer imaging and displays is unparalleled and is a direct result of a decade of advancement in semiconductor fabrication technologies that have made image sensors and displays less expensive but with higher resolution every passing year.
