# SimpleCV
# a kinder, gentler machine vision python library
#-----------------------------------------------------------------------
# SimpleCV is an interface for Open Source machine
# vision libraries in Python.
# It provides a consise, readable interface for cameras,
# image manipulation, feature extraction, and format conversion.
# Our mission is to give casual users a comprehensive interface
# for basic machine vision functions and an
# elegant programming interface for advanced users.
