caffe copy pretrained weights to train a network which supports for larger input

问题

How can I use the pretrained e.g. AlexNet model to train a CNN which supports larger (e.g. 500x500) input image sizes?

In other words, how to copy only the convolutional filters to the new network (using Matlab wrapper)?
