Python OpenCV Utilities is a module that provides useful extensions.

It contains useful and convenient features.

Python OpenCV Utilities requires:

• opencv-python
• pillow
• urllib3
• scikit-learn

To use the Python OpenCV Utilities algorithm, proceed as follows:

pip install python-opencv-utils

You use rotateEx function as follows:

import cv2u as cv2

src = cv2.imread("image.jpg")
dst = cv2.rotateEx(src, 45)

cv2.imshow("src", src)
cv2.imshow("dst", dst)
cv2.waitKey()

src	dst

You use DBSCAN function as follows:

import cv2u as cv2

src = cv2.imread("image.jpg")
maps, labels = cv2.DBSCAN(src, 1.7, 2)
dst = cv2.drawDBSCAN(src, maps, labels)

cv2.imshow("src", src)
cv2.imshow("dst", dst)
cv2.waitKey()

src	dst

You use extensions flag as follows:

import cv2u as cv2

src = cv2.imread("image.jpg")
dst = cv2.flip(src, cv2.FLIP_MODE_X)

cv2.imshow("src", src)
cv2.imshow("dst", dst)
cv2.waitKey()
