Description	In our study we tested feasibility to detect and classify minerals indicating alteration processes in granite rocks (the Jizera-type granite) using high-resolution photographs taken sequentially in the Bedřichov water supply tunnel. The altered zones in granite could be visually depicted as the newly created secondary minerals changed colours of the original rock. We pre-processed the whole sequence of individual photographs and created seamless xyz-oriented photo-mosaics. Then the ISODATA algorithm was employed to automatically depict altered zones in the digital image.
