The SRGAN model is a Convolutional Neural Network(CNN) model. share. Started in Hack the Valley 2, 2018. I believe from their code on Github, they have a possible data leakage (in the same vein of the current issue raised there) as well as an accuracy of 100% on a test set is fishier than a fish . First it will pre-train the generator using MSE error for 2 epochs, then it will train the full GAN (generator + discriminator) for 100 epochs, using content (mse + vgg) and adversarial loss.

You can start training out-of-the-box with the CIFAR-10 or CIFAR-100 datasets, to emulate the paper results however, you will need to download and clean the ImageNet dataset yourself. Sieun Park. SR received substantial attention from within the computer vision research community and has a wide range of applications. These images are generated from LR images into 4x SR with trained with with the code. Throughout the project, we denote the directory you cloned the repo as SRGAN-tensorflow_ROOT, To run the training process, things will become a little complicated. SRGAN is hopefully implementation soon. TensorLayerX Implementation of "Photo-Realistic Single Image Super-Resolution Using a Generative Adversarial Network" Save it as imgBatch.t7 Prepare_file.py. Warning: the dataset is 18GB in size and will take some time to download! The paper above proposes a residual block-based neural network to super-resolve images, a VGG loss to improve the MSE loss that often fails to enforce fine SR image generation. This will start a training session in the GPU. A tag already exists with the provided branch name. execute the script: Launch tensorboard to monitor the training process, The training process in the tensorboard should be like this, Launch the tensorboard to monitor the training process. The highly challenging task of estimating a high-resolution (HR) image from its low-resolution (LR)counterpart is referred to as super-resolution (SR). Both training and testing only need to modify the srresnet_config.py file and srgan_config.py file. To reproduce the score evaluations of the benchmark datasets: To also get the super-resolved images of the benchmark dataset, you can pass the infer flag -i to the script. If memory is not big enough, will print 'oom' and move on. In this section, we will write the implementation for all the networks. The result is obtained following to same setting from the v5 edition of the paper on arxiv. This could be because of many things, as GAN training is rather unstable and can vary a lot even based on just random initialization. Passionate about learning new technology. th train-SRResNet.lua -model_name 9x9-15res-LR24 17 minutes ago. To review, open the file in an editor that reveals hidden Unicode characters.
