Statement

Chuck Close is an American painter and photographer who is known for his portraits that are a mosaic of blocks called "marks". These portraits have a strange duality -- the faces appear three-dimensional and clear from far away, but flat and unfocused at closer distances. We developed an algorithm to apply to digital images in order to create digital portraits in the style of Chuck Close. A tiling is placed over the initial image (in this example, the tiles or "marks" are triangles), and within each tile, an analysis is done with wavelet filters to determine the shapes in the tile. A separate analysis is done to choose colors within the triangles. For this work, we have created a portrait of Ramanujan, the famous Indian mathematician.

Artworks

Both the subject of this work and the method of creation are intricately mathematical. Ramanujan is the famous 20th century Indian mathematician who established or conjectured a broad collection of results in number theory. He caught the attention of Hardy, who recognized Ramanujan's genius. To create this digital image in the style of Chuck Close, wavelet filters were used to detect the existence and orientation of edges in the original image, and other calculations were made to determine the colors in the "marks".
