imresize

imresize(img: np.ndarray, size: tuple[int | None, int | None], interpolation: str | int | INTER = INTER.BILINEAR, return_scale: bool = False)

• Description: Resizes the input image.

• Parameters

  • img (np.ndarray): The input image to be resized.
  • size (tuple[int | None, int | None]): Target size (height, width). If one dimension is None, the other is inferred to keep the aspect ratio.
  • interpolation (str | int | INTER): Interpolation method. Available options: INTER.NEAREST, INTER.BILINEAR, INTER.CUBIC, INTER.AREA, INTER.LANCZOS4. Default is INTER.BILINEAR.
  • return_scale (bool): Whether to return the scaling ratio. Default is False.

• Returns

  • np.ndarray: The resized image.
  • Tuple[np.ndarray, float, float]: The resized image along with the width and height scaling ratios.

• Example

  import capybara as cb
  
  img = cb.imread('lena.png')
  
  # Resize the image to H=256, W=256
  resized_img = cb.imresize(img, [256, 256])
  
  # Resize the image to H=256, keeping the aspect ratio
  resized_img = cb.imresize(img, [256, None])
  
  # Resize the image to W=256, keeping the aspect ratio
  resized_img = cb.imresize(img, [None, 256])
