warp-based-CAIR

A simple warp-based CAIR algorithm

This algorithm uses OpenCV to perform a content-aware resizing operation on an image.

resize(I: np.ndarray, E: np.ndarray, target_size: (int, int), mode: int) -> np.ndarray

I:            The input image as an ndarray with the shape (i, j, channels)
E:            The energy map for I as an ndarray with the shape (i, j)
target_size:  The target size for warping the image, as a tuple of 2 integers
mode:         The resize mode for CAIR:
              mode = 0: Directly resize the image to the target size
              mode > 0: Resizes the image with a fixed aspect ratio so that its dimensions are
              greater or equal to target, and then performs CAIR.
              mode < 0: Resizes the image with a fixed aspect ratio so that its dimensions are
              smaller or equal to target, and then performs CAIR.
