AB WE  HAVE  SEEN  IN  Chapters  21  and  22  that  the  eye  is  not  a  mere  camera,  but  instead  contains  sophisticated  retinal  circuitry  that  decomposes  the  retinal  image  into  signals  representing  contrast  and  movement.  These  data  are  conveyed  through  the  optic  nerve  to  the  primary  visual  cortex,  which  uses  this  information  to  analyze  the  shape  of  objects.  It  first  identifies  the  boundaries  of  objects,  represented  by  numerous  short  line  segments,  each  with  a  specific  orientation.  The  cortex  then  integrates  this  information  into  a  representation  of  specific  objects,  a  process  referred  to  as  contour  integration.
