When artist Steve Miller met Nobel Laureate Rod MacKinnon at Brookhaven National Laboratory in New York, MacKinnon was investigating protein structures: specifically, how potassium ions move across cell membranes. Miller became fascinated with the visual tools MacKinnon used to grapple with the problem: 3D computer models of proteins, graphical equations and diagrams in the scientist’s notebook...

The structure of paintings : formal grammar and design ’

Although substantial literature exists on the properties of formal grammars, much less has been written on the use of grammars for describing the languages which they are capable of explaining.

We addressed the problem of automatically differentiating photographs of real scenes from photographs of paintings. We found that photographs differ from paintings in their color, edge, and texture properties. Based on these features, we trained and tested a classifier on a database of 6000 paintings and 6000 photographs. Using single features results in 70–80% correct discrimination performanc...
