image - How to convert image from double to uint8 in matlab?

Witryna30 mar 2024 · 1 Answer. Sorted by: 1. A simple solution to this could be to explicitly typecast unit8 to the image while plotting it with matplotlib.pyplot. Just replacing this code plt.imshow (img_tinted) with plt.imshow (np.uint8 (img_tinted)) resolved the issue. Here's the sample output. You can even play further with the images. http://python1234.cn/archives/ai30145 chuck rosebrough https://thesimplenecklace.com
