Tensorflow的逆变换挤压

Question

我想在形状为tf.image.crop_and_resize的3-D张量的图像上使用[image_height, image_width, depth]，但tf.image.crop_and_resize期望形状为{[batch, image_height, image_width, depth]的4-D张量1}}。

我怎样才能暂时＆＃34;不挤压＆＃34;插入批量维度？

Answer 1

您可以使用tf.expand_dims将3-D图片制作成4-D batch size形状的tf.image.crop_and_resize(tf.expand_dims(image, 0), ...) 。
