We attempt to learn a demoireing model from unpaired real data, i.e., moire images associated with irrelevant clean images.
We introduce an adaptive denoise method to eliminate the low-quality pseudo moire images that adversely impact the learning of demoireing models.

- Abstract: This paper focuses on addressing the issue of image demoireing. Unlike the
large volume of existing studies that rely on learning from paired real data,
we attempt to learn a demoireing model from unpaired real data, i.e., moire
images associated with irrelevant clean images. The proposed method, referred
to as Unpaired Demoireing (UnDeM), synthesizes pseudo moire images from
unpaired datasets, generating pairs with clean images for training demoireing
models. To achieve this, we divide real moire images into patches and group
them in compliance with their moire complexity. We introduce a novel moire
generation framework to synthesize moire images with diverse moire features,
resembling real moire patches, and details akin to real moire-free images.
Additionally, we introduce an adaptive denoise method to eliminate the
low-quality pseudo moire images that adversely impact the learning of
demoireing models. We conduct extensive experiments on the commonly-used FHDMi
and UHDM datasets. Results manifest that our UnDeM performs better than
existing methods when using existing demoireing models such as MBCNN and
ESDNet-L. Code: https://github.com/zysxmu/UnDeM

- On the Effectiveness of Dataset Alignment for Fake Image Detection [28.68129042301801]
A good detector should focus on the generative models fingerprints while ignoring image properties such as semantic content, resolution, file format, etc.
In this work, we argue that in addition to these algorithmic choices, we also require a well aligned dataset of real/fake images to train a robust detector.
For the family of LDMs, we propose a very simple way to achieve this: we reconstruct all the real images using the LDMs autoencoder, without any denoising operation. We then train a model to separate these real images from their reconstructions.

We investigate a suite of image generation models that produce images from simple random processes.
These are then used as training data for a visual representation learner with a contrastive loss.
Our findings show that it is important for the noise to capture certain structural properties of real data but that good performance can be achieved even with processes that are far from realistic.

Moire artifacts are common in digital photography, resulting from the interference between high-frequency scene content and the color filter array of the camera.
Existing deep learning-based demoireing methods trained on large scale iteration are limited in handling various complex moire patterns.
We propose a self-adaptive learning method for demoireing a high-frequency image, with the help of an additional defocused moire-free blur image.
