Nothing to worry...
Friends,
My left hand ring-finger had several warnings... the guy who was taking the finger prints asked me to just relax and cleaned few times until the print was read clear.... no big deal. The matching is not done there... and the finger prints will be sent to FBI for matching.
The error comes if the grey scale value (a bit technical, since I'm in the related field... the scan imprint will be converted to a black and white image and the darkest portion of the image should have close to 25 counts and the lightest portion should have 225 counts and if the histogram of the image is not 'peaked' properly.... ) the scan complains of warning... this poor image could (?) not be used as a good sample to compare with other images in the database or return bad results... you guys take it easy.
TIA.
