Instructions
* Fill in the missing words into the blank fields
Is  that  person  really  glad  to  see  me?  Or  are  they  just    polite?  Some  people  struggle  to  distinguish  a      grin  from  a  truly  happy  smile.  And  computers  have  found  this  task  even  more  difficult,  that  is,  until  researchers    a  program  to  detect  when  a  smile  is  genuine.  
Visual  computing  researchers  at  the  University  of  Bradford  in  the  U.K.  started  with  software  for    a  changing  facial  expression.  This  program  can  examine  a  video  clip  of  a  human  head  and  identify  specific    around  the  eyes,  cheeks  and  mouth.  Then  the  program  tracks  the  details  moving  relative  to  each  other  as  the  face  smiles.  Next,  the  scientists  had  their  program    two  sets  of  video  clips.  In  one,  subjects  performed  posed  smiles.
