imresize

imresize(img: np.ndarray, size: Tuple[int, int], interpolation: Union[str, int, INTER] = INTER.BILINEAR, return_scale: bool = False) -> Union[np.ndarray, Tuple[np.ndarray, float, float]]

• Description: Resizes the input image.

• Parameters

  • img (np.ndarray): The input image to be resized.
  • size (Tuple[int, int]): The target size of the resized image. If only one dimension is given, the other dimension is calculated to maintain the original aspect ratio.
  • interpolation (Union[str, int, INTER]): The interpolation method. Available options include: INTER.NEAREST, INTER.LINEAR, INTER.CUBIC, INTER.LANCZOS4. Default is INTER.LINEAR.
  • 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])
