class digital_image_processing.dithering.burkes.Burkes(input_img, threshold: int)¶

Burke’s algorithm is using for converting grayscale image to black and white version Source: Source: https://en.wikipedia.org/wiki/Dither

Note:

Best results are given with threshold= ~1/2 * max greyscale value.
This implementation get RGB image and converts it to greyscale in runtime.

classmethod get_greyscale(blue: int, green: int, red: int) → float¶

>>> Burkes.get_greyscale(3, 4, 5)
4.185
>>> Burkes.get_greyscale(0, 0, 0)
0.0
>>> Burkes.get_greyscale(255, 255, 255)
255.0
