This article focuses on "how Python converts 2D numpy arrays into grayscale images". Interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how Python converts a 2D numpy array into a grayscale image.

From PIL import Image# image_array is a normalized two-dimensional floating-point matrix image_array * = 255# transformed into a gray value im = Image.fromarray (image_array) im = im.convert ('L') # so that it can be converted into a grayscale image. If it is a color image, then change L to 'RGB'im.save (' outfile.png'). I believe you have a better understanding of "how Python converts a two-dimensional numpy array into a grayscale image". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
