convert image from CV_64F to CV_8U

Question

I want to convert an image of type CV_64FC1 to CV_8UC1 in Python using OpenCV.

In C++, using convertTo function, we can easily convert image type using following code snippet:

image.convertTo(image, CV_8UC1);

I have searched on Internet but unable to find any solution without errors. Any function in Python OpenCV to convert this?

Answer 1

You can convert it to a Numpy array.

import numpy as np

# Convert source image to unsigned 8 bit integer Numpy array
arr = np.uint8(image)

# Width and height
h, w = arr.shape

It seems OpenCV Python APIs accept Numpy arrays as well. I've not tested it though. Please test it and let me know the result.
