The scales in each group varied in age from 2 to 10 yr. A comparison of the image processed digitized Fourier transforms for the scales was made on a personal computer. Statistical correlation studies of these transforms were performed, and the results show a fairly good age discrimination between the scales in each age group.en-USIn CopyrightArticle - Refereedhttp://www.opticsinfobase.org/ao/abstract.cfm?URI=ao-26-12-2299https://doi.org/10.1364/AO.26.002299
