Moiré pattern reduction by using special designed parallax barrier in an autostereoscopic display

SPIE Proceedings, 2010
The moire pattern is caused by the spatial interference of two regular pattern structures. In the case of an autostereoscopic display, it's caused by the overlap of the parallax barrier and the black matrix among pixels of FPD. To minimize the moire effect, we simulate the relationship of brightness distribution and various design parameters of the ...

X-ray moiré patterns of silicon crystals with distortions caused by local concentrated forces

SPIE Proceedings, 2011
We study the mechanisms of forming X-ray moire images arising under the action of one-dimensional rows of local concentrated forces at output surface of a surface of triple-crystalline-interferometer for the cases of orientation of them parallel and perpendicular to the vector of diffraction. Presence of constant phase shift of one of the interfering

Moiré Pattern Removal with Multi-scale Feature Enhancing Network

2019 IEEE International Conference on Multimedia & Expo Workshops (ICMEW), 2019
Taking high-quality photos of digital screens is difficult, as such photos are usually contaminated with moire patterns. Considering the nature of wide-range frequencies of moire' patterns, existing works adopt the multi-scale framework to address this ...

Moiré Pattern Detection using Wavelet Decomposition and Convolutional Neural Network

IEEE Symposium Series on Computational Intelligence, 2018
Moiré patterns are interference patterns that are produced due to the overlap of the digital grids of the camera sensor resulting in a high-frequency noise in the image.

Beyond the Screen: Evaluating Deepfake Detectors under Moiré Pattern Effects

2024 IEEE/CVF Conference on Computer Vision and Pattern Recognition Workshops (CVPRW)
The detection of deepfakes is crucial for mitigating the societal impact of falsified video content. Despite the development of various algorithms for this purpose, challenges arise for detectors in real-world scenarios, especially when users capture ...

Rotation-Selective Moiré Magnification of Structural Color Pattern Arrays.

ACS Nano, 2019
When a microlens array is aligned and overlaid on an array of patterns with similar periodicity, a highly magnified image of the patterns is observed. This effect, known as moiré magnification, is used to reveal micropatterns that are unresolvable by the
