# Upon importing, this module adds the following python module
|
||
|
|
# directories from the dev tree to sys.path (i.e. PYTHON_PATH):
|
||
|
|
# opencv/interfaces/swig/python and opencv/lib
|
||
|
|
#
|
||
|
|
# Using it in a test case is simple, just be sure to import
|
||
|
|
# cvtestutils before cv, highgui, etc
|
||
|
|
#
|
||
|
|
# Usage:
|
||
|
|
# import cvtestutils
|

|
# import cv
