Python 不推荐使用的scipy imresize（）函数的替代方案？

我曾经使用scipy resize函数来缩小图像的比例。但由于最新版本的scipy中不推荐使用此函数，因此我正在寻找替代方法。PIL似乎很有前途，但我如何将其用于3d图像？（600800,3）至（300400,3）

我研究了numpy.resize、skimage，但特别是skimage，我不确定它是否与scipy的imresize（）完全一样。

是使用OpenCV调整彩色图像大小的一种方法

import numpy as np
import cv2

image = cv2.imread('image.png')
cv2.imshow("Original", image)
"""
The ratio is r. The new image will
have a height of 50 pixels. To determine the ratio of the new
height to the old height, we divide 50 by the old height.
"""
r = 50.0 / image.shape[0]
dim = (int(image.shape[1] * r), 50)

resized = cv2.resize(image, dim, interpolation = cv2.INTER_AREA)
cv2.imshow("Resized (Height) ", resized)
cv2.waitKey(0)

如中所述，您可以改用

numpy.array（Image.fromarray（arr.resize（））

另外，在

scipy.misc

模块中还有许多其他不推荐使用的图像函数。你可以检查一下。如果网站发生变化，我也会引用它们：

你试过openCV吗？嗨，阿文，我以为cv2的大小调整只需要2d数组？我查看了cv2（openCV），发现：导入cv2内容\u image=scipy.misc.imread（“images/louvre.jpg”）内容\u image=cv2。调整大小（内容\u image，无，fx=0.5，fy=0.5）效果很好！参数是否相同？我假设

def imresize（arr，*args，**kwargs）：返回numpy.array（Image.fromarray（arr）.resize（*args，**kwargs））

将作为替代品使用？我正在尝试让代码在我不完全理解的1.2上运行。
