sample code for using lib quickMTF

.. code-block:: python

from quickMTF.quickMTF import quickMTF import cv2

if name == 'main': test = quickMTF() ROI_width = 600 ROIX = 1593 ROIY = 1500 image = cv2.imread("image.jpg") image = image[ROIY:ROIY+10, ROIX:ROIX+ROI_width]

   print(test.quicklinepairMTF(image, library='cv2'))  # linepair chart MTF value and pixels/line pair
   print(test.quicksfrMTF(image, cp=0.5))  # CP means cycles/pixel and out MTF value per c/p and slant angle
   print(test.quicksfrCP(image, mtf_indx=30))  # MTFindex means MTF and out Cycles/pixel per MTF value and slant angle
