<p class="text">DPE is a proposed solution for Super Resolution and Artifact Reduction on low resolution images. </p>
<p class="text">
Current neural networks for super resolution, such as <a href="https://arxiv.org/abs/1707.02921">EDSR</a>, have shown good results in performing super resolution,
but they do not tackle the issue of artifact reduction. We suggested that by fine-tuning existing networks we will also be able to perform artifact reduction and
acheive good results in both aspects

This project was conducted on semester Winter 2018-2019, as an industrial project (234313)

<h3 class="section-subheading text">How did we plan to do it?</h3>
<p class="text">
In order to be able to perform both Super Resolution and Artifact Reduction on low quality images, we have decided to use an existing network and modify it.
We took the <a href="https://github.com/thstkdgus35/EDSR-PyTorch">EDSR PyTorch Implementation</a> and trained it with a custom dataset we created after researching what would help it perform best.
</p>
<p class="text"> Using the <a href="https://data.vision.ee.ethz.ch/cvl/DIV2K/">DIV2K</a> dataset, we built a training set that included downscaled images that were saved in different formats.
Some of these formats suffer from artifacts.
</p>
<p class="text">
We tested our performance comparing to a simple upscaling of the low resolution images. The images we used for testing are the validation set of DIV2K (images 0801-900).

<p>
In this image we see the best improvement (percentage-wise, when considering SSIM error) for images that were saved with Q factor = 75.
As we can observe, the image gets sharper.
Note there is still a bit of blur right above the building.

<p>This image is some of the visual proofs that our network performs artifact reduction. When considering the areas of the yellow tiles we can see the apparent difference.</p>
