title: Can Keras deal with input images with different size?
body: <p>Can the Keras deal with input images with different size? For example, in the fully convolutional neural network, the input images can have any size. However, we need to specify the input shape when we create a network by Keras. Therefore, how can we use Keras to deal with different input size without resizing the input images to the same size? Thanks for any help.</p>
