python图片大小归一化

以下是使用Python进行图片大小归一化的示例代码：

from PIL import Image

def resize_image(input_image_path, output_image_path, size):
    original_image = Image.open(input_image_path)
    width, height = original_image.size
    print(f"The original image size is {width} wide x {height} high")

    resized_image = original_image.resize(size)
    width, height = resized_image.size
    print(f"The resized image size is {width} wide x {height} high")
    resized_image.show()
    resized_image.save(output_image_path)

if __name__ == '__main__':
    resize_image('input_image.jpg', 'output_image.jpg', (800, 800))

在上述代码中，我们使用了Python的Pillow库来处理图片。`resize_image`函数接受三个参数：输入图片路径、输出图片路径和目标大小。函数首先打开输入图片，获取其原始大小，然后将其缩放到目标大小，并保存为输出图片。最后，函数会显示缩放后的图片。
