image/jpeg text/html born digital general The color images included in this Web site were obtained by automatically registering three images, originally captured by Sergeĭ Mikhaĭlovich Prokudin-Gorskiĭ in black and white on glass plate negatives, using red, green and blue filters to obtain a color image. The computer program that combines these three images to form a color composite image was written in MATLAB by Frank Dellaert using computer-vision technology commonly used in 'mosaicking'. By clicking the links you can view thumbnails of the almost 2000 images acquired by the Library of Congress. Each thumbnail is linked to a larger version of the corresponding color image. We know that Prokudin-Gorskii intended his photographic images to be viewed in color because he developed an ingenious photographic technique in order for these images to be captured in black and white on glass plate negatives, using red, green and blue filters. He then presented these images in color in slide lectures using a light-projection system involving the same three filters. www.cs.cmu.edu/~dellaert/aligned/ Prokudin-Gorskii, Sergei Mikhailovich 1863-1944 photographer.
