Applies Otsu's thresholding method to a grayscale image.

Module Contents

computer_vision.otsu_threshold.otsu_threshold(image: PIL.Image) → PIL.Image

Applies Otsu’s thresholding method to a grayscale image.

Parameters: image (PIL.Image.Image): A grayscale PIL image object.

Returns: PIL.Image.Image: A binary image after applying Otsu’s thresholding.

Example: >>> from PIL import Image >>> import numpy as np >>> image_array = np.array( … [[0, 0, 0, 0], [255, 255, 255, 255], [0, 0, 0, 0], [255, 255, 255, 255]], … dtype=np.uint8 … ) >>> image = Image.fromarray(image_array) >>> binary_image = otsu_threshold(image) >>> np.array(binary_image) array([[ 0, 0, 0, 0],

[255, 255, 255, 255], [ 0, 0, 0, 0], [255, 255, 255, 255]], dtype=uint8)
