- Abstract: Fundus images are very useful in identifying various ophthalmic disorders.
However, due to the presence of artifacts, the visibility of the retina is
severely affected. This may result in misdiagnosis of the disorder which may
lead to more complicated problems. Since deep learning is a powerful tool to
extract patterns from data without much human intervention, they can be applied
to image-to-image translation problems. An attempt has been made in this paper
to automatically rectify such artifacts present in the images of the fundus. We
use a CycleGAN based model which consists of residual blocks to reduce the
artifacts in the images. Significant improvements are seen when compared to the
existing techniques.

using Diffusion Models [36.81751569090276]
Counterfactual reasoning is often used in clinical settings to explain decisions or weigh alternatives.
Here, we demonstrate that using a diffusion model in combination with an adversarially robust classifier trained on retinal disease classification tasks enables the generation of highly realistic counterfactuals.
In a user study, domain experts found the counterfactuals generated using our method significantly more realistic than counterfactuals generated from a previous method, and even indistinguishable from real images.

We propose a new method to counteract blurring and contrast loss in microscopy images.

We trained a neural network that learned the inverse of this degradation function from our generated pairs of raw and degraded images.

Deep Learning (DL) models have achieved state-of-the-art performance in diagnosing multiple diseases using reconstructed images as input.
DL models are sensitive to varying artifacts as it leads to changes in the input data distribution between the training and testing phases.
We propose to use other normalization techniques, such as Group Normalization and Layer Normalization, to inject robustness into model performance against varying image artifacts.

We identify a surjection problem with artifact removal, and propose a weakly-supervised extension to CycleGAN to address this.
We assemble a pan-cancer dataset comprising artifact and clean tiles from the TCGA database.

We propose the first turbulence mitigation method that makes use of visual priors encapsulated by a well-trained GAN.
Based on the visual priors, we propose to learn to preserve the identity of restored images on a periodic contextual distance.
Our method significantly outperforms prior art in both the visual quality and face verification accuracy of restored results.

generative models can synthesize "views" of artificial images that mimic real-world variations, such as changes in color or pose.
Here, we investigate whether such views can be applied to real images to benefit downstream analysis tasks such as image classification.
We use StyleGAN2 as the source of generative augmentations and investigate this setup on classification tasks involving facial attributes, cat faces, and cars.
