kandi X-RAY | SRGAN Summary

SRGAN is a Python library typically used in Artificial Intelligence, Machine Learning, Deep Learning, Pytorch, Tensorflow applications. SRGAN has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. However SRGAN build file is not available. You can download it from GitHub.

A tensorflow implementation of Christian et al's "Photo-Realistic Single Image Super-Resolution Using a Generative Adversarial Network" paper. ( See : ) This implementation is quite different from original paper. The differences are as followings:. The existing CNN based super-resolution skill mainly use MSE loss and this makes super-resolved images look blurry. If we replace MSE loss with gradients from GAN, we may prevent the blurry artifacts of the super-resolved images and this is the key idea of this paper. I think this idea looks promising and my experiment result using MNIST data set looks good.

            I'm implementing SRGAN (and am not very experienced in this field), which uses a pre-trained VGG19 model to extract features. The following code was working fine on Keras 2.1.2 and tf 1.15.0 till yesterday. then it started throwing an "AttributeError: module 'keras.utils.generic_utils' has no attribute 'populate_dict_with_module_objects'" So i updated the keras version to 2.4.3 and tf to 2.5.0. but then its showing a "Input 0 of layer fc1 is incompatible with the layer: expected axis -1 of input shape to have value 25088 but received input with shape (None, 32768)" on the following line

            Why and How to make range of Output image from a Neural Network [-1,1] in SRGAN?
            Asked 2020-Jul-23 at 04:06

            I've been working on reimplementing Photo-Realistic Single Image Super-Resolution Using a Generative Adversarial Network (SRGAN), now I'm stuck with the given information in section 3.2. Based on the paper, the target HR should be in the range [-1,1], the input LR should be in the range [0,1], and MSE loss was calculated on images in range [-1,1].

            The last sentence implies that the output from the generator network should be in [-1,1]. So that the content_loss = MSELoss(generator(output), target). Am I understanding correctly? But when I print the output from my generator network, whose laster is just a conv2d, it gives me images in the rage [0,1].

            I'm not getting a good result by running SRResNet-MSE part, and I think maybe because the MSE loss is calculating on different ranges instead of just one [-1,1]?

            But how can the output from my generator be in range [-1,1] if I still want to follow paper's architecture, which has conv2d as the last layer?

            I also include my code Class Generator here

            How to save a jupyter notebook with outputs
            Asked 2020-Jun-09 at 18:12

            How can I save a jupyter notebook with outputs? I'm editing my notebook with Google Collab and want to save it as a .ipynb file with outputs shown, like here: https://nbviewer.jupyter.org/github/krasserm/super-resolution/blob/master/example-srgan.ipynb.

            But when I Download .ipynb on Google Collab, you can't see the outputs in the resulting file. How can I get the outputs to show?

            Related question: how can I have the outputs save in the Google Collab doc? Right now, the outputs always disappear on reload, even though I disabled the hide outputs on save.

            1. When I downloaded it did show me the content. Make sure you used Save on the notebook before downloading (I uploaded my result to https://nbviewer.jupyter.org/ and it worked and showed the preview). If it doesn't work, check the next item on my list.

            2. Double-check the settings at "Settings" -> "Site" and make sure "New notebooks use private outputs (omit outputs when saving)" is disabled. Similarly, check also "Edit" -> "Notebook settings" and make sure "Omit code cell output when saving this notebook" is disabled. Yes, these are two separate settings.

            3. Retry 1# if it didn't work before after toggling both settings. Also, notebooks should now save the output.

            Enhancing the resolution of an image
            Asked 2020-Feb-21 at 02:22

            I have images that are having very low quality and these images I have to use for person identification but with this quality it's difficult to detect. I want to enhance the quality of the images using deep learning/machine learning techniques. I have studied about SRCNN, perceptual Loss, SRResNet, SRGAN but most of the super image resolution techniques require original images for improving the quality of the images. So my question is there any deep learning techniques that can be used for the improving the quality of the images without using the original images.
