SUMMARY:Bar Code Scanning -- An Inverse Problem for Words - Santosa\, F (U
 niversity of Minnesota)

DESCRIPTION:Bar codes are ubiquitous -- they are used to identify products
  in stores\, parts in a warehouse\, and books in a library\, etc.  In this
  talk\, the speaker will describe how information is encoded in a bar code
  and how it is read by a scanner.  The presentation will go over how the d
 ecoding process\, from scanner signal to coded information\, can be formul
 ated as an inverse problem.  The inverse problem involves finding the "wor
 d" hidden in the signal.  What makes this inverse problem\, and the approa
 ch to solve it\, somewhat unusual is that the unknown has a finite number 
 of states.\n
