How to realize OpenCV addition operation in python

This article mainly shows you "how to achieve OpenCV addition operation in python", the content is easy to understand, clear, hope to help you solve your doubts, the following let the editor lead you to study and learn "how to achieve OpenCV addition operation in python" this article.

Description

1. Use cv2.add () to add two images in opencv, and the core operation is to add matrices in numpy.

2. The method of adding opencv is saturation operation, that is, there is an upper limit.

The two pictures added together need the same size and channel.

Syntax format:

Cv2.add (src1, src2, dst=None, mask=None, dtype=None)

Return value: the added image.

Where src1 and src2 need equal size and number of channels or an image and a scalar (scalar is a single number)

The code example is as follows:

Import cv2 as cv def img_add (src1, src2): res = cv.add (src1, src2) cv.imshow ("add", res) if _ _ name__ = = "_ _ main__": src1= cv.imread (". / src1.jpg") src2= cv.imread (". / src2.jpg") img_add (src1=src1, src2=src2) cv.waitKey (0) above are all the contents of the article "how to implement OpenCV addition in python" Thank you for reading!
