Our code and dataset are released in the link. Experimental results demonstrate that our method outperforms state-of-the-art demoiréing methods on a large set of test images. A group of self-supervised loss functions, including cycle consistent loss, identity loss, cosine similarity loss, and content leakage loss, are designed to train effective generators. We propose two complementary discriminator groups to effectively distinguish moiré patterns and image features at both large scales and small scales. Use the arrow buttons to the left and right of the. At the same time, the foreground pattern will start to rotate. To operate the tutorial, first click the Auto button and it will turn into a red Manual button.

The recaptured images are corrected against vignetting artifacts to make MR-GAN focus on correcting brightness and contrast distortions while removing moiré patterns. This tutorial combines a rotating foreground with a stationary background pattern to create a wide spectrum of optical illusion effects. I cant screenshot what I did here since Moiré Patterns appear just from screenshotting. This paper proposes an unsupervised Generative Adversarial Network for Moiré Removal (MR-GAN), which is the first attempt at unsupervised learning based moiré removal. The most obvious Moiré Patterns are (M(1,b)) where (b) is a small integer If the most obvious Moiré Pattern is (M(1,b)), the second is (M(1,b+1)) I scaled the SVG such that the edge of the pattern to the center fills most of my screen.

The pdf files given below can be downloaded and printed to illustrate the. Chapter 16 in the second edition of the book Optical Shop Testing describes the relationship between moiré patterns and interferometry.

Prevalent supervised-learning based methods require huge amount of paired images, which are difficult to capture and align. Moiré patterns are extremely useful to help understand basic interferometry and interferometric test results. The spatial variety in densities and scales makes it difficult to remove moiré patterns with hand-crafted priors. Moiré patterns, mainly due to the aliasing between the grids of display devices and camera sensors, often occur in recaptured screen images (videos).
