Criminal
investigation often takes place hurriedly and under (to say the least)
less than favorable circumstances. It's 3 o'clock ing the morning and
raining; officials or family want to remove the body; and even seasoned
personnel are tired and disturbed by what they see. Crime scene investigators
are trained to make accurate maps, but it is impossible to determine completely
what sort of evidence will become important when legal proceedings take
place,often years later. The many photographs that forensic investigators
are also taught to take contain information that isn't even noticed at
the scene: bite marks, subtle blood spatter patterns, and tiny objects
on the floor. Ebert & Associates, Inc., had been using image processing,
digital photogrammetric and other forensic imaging and mapping techniques
to extract crucial forensic information and make maps and measurements
from photographs and other imaged data (for instance, video, which is
often of less-than-ideal quality) to aid in criminal investigations, prosecution,
and defense. |
