我的图片不会调整 tf.image.resize_with_padding tensorflow

Question

我的原始图像是 600*600 像素，我想将其调整为 300*300 像素

调整代码大小

import tensorflow as tf
import numpy as np
from tensorflow.keras.preprocessing.image import array_to_img
from tensorflow_core.python.keras.layers.image_preprocessing import ResizeMethod


def resize(image, w=300, h=300):

    image = tf.convert_to_tensor(np.asarray(image))
    size = (w, h)
    tf.image.resize_with_pad(
        image,
        h,
        w,
        method=ResizeMethod.BILINEAR
    )
    image = array_to_img(image)
    return image

保存图片后尺寸不变

保存图片代码

def write_images(images, path):
    try:
        index = 1
        for img in images:
            img.save(path+f'/{index}.jpeg')
            index += 1
    except:
        print('Error while writing images')

Tensorflow 操作不到位。您需要将调整大小操作的结果分配如下：

image = tf.image.resize_with_pad(
    image,
    h,
    w,
    method=ResizeMethod.BILINEAR
)
