imbinarize

imbinarize(img: np.ndarray, threth: int = cv2.THRESH_BINARY, color_base: str = "BGR") -> np.ndarray

Description: Performs binarization on the input image.
Parameters
- img (np.ndarray): The input image to binarize. If it has 3 channels, it is converted to grayscale via imcvtcolor(..., f\"{color_base}2GRAY\") first.
- threth (int): The threshold type. There are two threshold types:
  1. cv2.THRESH_BINARY: cv2.THRESH_OTSU + cv2.THRESH_BINARY
  2. cv2.THRESH_BINARY_INV: cv2.THRESH_OTSU + cv2.THRESH_BINARY_INV
- color_base (str): The color space of the input image. Default is 'BGR'.
Returns
- np.ndarray: The binarized image.

Example

import capybara as cb

img = cb.imread('lena.png')
bin_img = cb.imbinarize(img)
