ICA group Laboratory of Computer and Information Science Helsinki University of TechnologyThis is the image data used in our ICA experiments on natural images. The images are in TIFF format for easy reading into MATLAB using the 'imread' command. (They can also be viewed for example with the 'xv' program in unix.)
The photographs are copyrighted: © Janne Sinkkonen 1994, 1995, 1996, 1997. Copying is permitted only for noncommercial use.
Thanks are due to Janne Sinkkonen for taking the images. They are originally in color and of much higher resolution. You can take a tour of his work at his homepage.
