To reproduce our FCN training, or train your own FCNs, it is crucial to transplant the weights from the corresponding ILSVRC net such as VGG16. Fully Convolutional Networks for Semantic Segmentation - Notes ... AlexNet takes 1.2 ms to produce the classification scores of a 227x227 image while the fully convolutional version takes 22 ms to produce a 10x10 grid of outputs from a 500x500 image, which is more than 5 times faster than the naïve approach.

The included surgery.transplant() method can help with this. The training was done using Nvidia GTX 1080, on Linux Ubuntu 16.04. [11] O. Ronneberger, P. Fischer, and T. Brox. (Note: when both FCN-32s/FCN-VGG16 and FCN-AlexNet are trained in this same way FCN-VGG16 is far better; see Table 1 of the paper.). The encoder progressively reduces the spatial resolution and learns more abstract/semantic visual concepts with larger receptive fields.
