  22               Welcome to the Open Source Computer Vision Library.<br>
  23
  24               <br>
  25
  26               Gigahertz microprocessors, falling camera prices and ten
  27               times more video capture bandwidth from USB2 are
  28               providing new opportunities to apply computer vision
  29               anywhere you might find a PC. Real time gestural
  30               control around your home PC is now conceivable.
  31
  32               <br><br>
  33
  34               The Visual Interactivity Group in Intel's Microprocessor
  35               Research Lab initiated the development of this library 2
  36               years ago and has made two alpha releases of this code
  37               prior to this first Open Source release.  Our goal is to
  38               establish an open source vision community and provide a
  39               site where the distributed efforts of the community can
  40               be consolidated and performance optimized. The library
  41               is intended for use by researchers and commercial
  42               software developers.
  43
  44               <br><br>
  45
  46               Computer vision research is filled with many competing
  47               groups and ideas with no unifying theory of vision,
  48               typifying Thomas Kuhn's definition of a
  49               &quot;pre-paradigmatic science&quot;. In Kuhn's
  50               <i><u>Structure of Scientific Revolutions</u></i>, he
  51               argues that progress in a given scientific field derives
  52               from the acceptance of a common paradigm by which
  53               members of the group can <i>share and compare</i>. We
  54               cannot offer here that unifying theory of vision by
  55               which the field will cohere, but we can offer the
  56               community a central infrastructure by which we can share
  57               and compare. This is the driving research philosophy of
  58               this library, and by this we hope at least technical, if
  59               not scientific progress can be made.
  60
  61               <br><Br>
  62
  63               To involve and benefit from the combined expertise of
  64               the vision community we have recruited a <a
  65               href="#committee">committee</a> of experts to
  66               participate in acceptance decisions for new content for
  67               the library and in setting the library direction in
  68               general.  Intel's contribution is to provide its own
  69               research contributions, host the library on a website,
  70               and contribute assembly language optimized versions of
  71               the most compute intensive code.
