Inception-Score-FID-on-CUB-and-OXford

As the original tensorflow code is out of data, it's a bit troublesome to run the evaluation code.

Hence, we provide a new version of code to caculate Inception Score and FID on CUB and OXford with original weight for fair of comparison.

Note that the code will produce higher FID score than using weight without finetuning

For example, RAT-GAN scores 13.91 with this code. But using inception weight without finetuning , RAT-GAN scores 10.21.

This is because stackGAN fine-tuned the inception weights on CUB, which makes FID to be more aware of the difference of bird images. According to my experience, when the FID grows smaller, this code better distinguishes the image quality.

Requirements

• python 3.8
• Tensorflow 2.7.0+cu113
• scikit-image
• pillow

Usage:

download inception_finetuned_models from StackGAN

1.Change the file path to the location of generated images

2.Change the modl path to the location of fine-tuned inception models

3.Just run python inceptionscore_dir_cub.py
