请问，python中有图像预处理resize_short和crop_image， def resize_short(img, target_size): """resize image

Args:
    img: image data
    target_size: resize short target size
    interpolation: interpolation mode

Returns:
    resized image data
"""
percent = float(target_size) / min(img.shape[0], img.shape[1])
resized_width = int(round(img.shape[1] * percent))
resized_height = int(round(img.shape[0] * percent))
resized = cv2.resize(img, (resized_width, resized_height))
return resized

def crop_image(img, target_size, center): """crop image

Args:
    img: images data
    target_size: crop target size
    center: crop mode

Returns:
    img: cropped image data
"""
height, width = img.shape[:2]
size = target_size
if center == True:
    w_start = (width - size) // 2
    h_start = (height - size) // 2
else:
    w_start = np.random.randint(0, width - size + 1)
    h_start = np.random.randint(0, height - size + 1)
w_end = w_start + size
h_end = h_start + size
img = img[h_start:h_end, w_start:w_end, :]
return img

这个需要自己用java和c++实现还是有lite库里的api可以调用？如果有，api该怎么用呢
