neural-style-pytorch

A simple PyTorch implementation of "A Neural Algorithm of Artistic Style"

introduction

I try some other codes for neural-style-pytorch, but their outputs may become noise in some epochs, such as epoch 45, 170 and 230 in Figure 1. I don't know why. Therefore, I simply implement the method of "A Neural Algorithm of Artistic Style (http://arxiv.org/abs/1508.06576).

Results

The output as shown in Table 1.

Outputs of some epochs as shown in Figure 2 and Table 2, the outputs may be more stable, and will not become noise suddenly.

Acknowledge

Thanks for the reference codes as following:

The main program is neural_style.py. Inspired by [1], I calculate the losses in iterations directly, instead of modeling them in network. I also remove the normalization, and use Adam optimizer.

The optimization speed of this code may be slower than other PyTorch codes, which needs more epochs.
