Checkerboard pattern of artifacts
WebJul 11, 2024 · Our analysis explains the appearance of so-called checkerboard patterns and border artifacts. Moving the network into the chaotic regime prevents checkerboard patterns; we propose a graph-based parametrization which eliminates border artifacts; finally, we introduce a new layer-dependent learning rate to improve the convergence of … WebDec 1, 2024 · Abstract: In this paper, we propose a novel CycleGAN without checkerboard artifacts for counter-forensics of fake-image detection. Recent rapid advances in image manipulation tools and deep image synthesis techniques, such as Generative Adversarial Networks (GANs) have easily generated fake images, so detecting manipulated images …

If we decide to use rotated grid 4x pattern, we get 4x larger rotated box. This one is a bit different. We get a lot more horizontal and vertical anti-aliasing and a bit more diagonal anti-aliasing. Near horizontal and near vertical lines will observe a ...
WebFeb 19, 2024 · It is well-known that a number of convolutional neural networks (CNNs) generate checkerboard artifacts in both of two processes: forward-propagation of upsampling layers and backpropagation of convolutional layers.

WebGPU artifacts can look like just about anything and can get sufficiently severe that nothing on the screen is recognizable. A common form of serious GPU artifact is a checkerboard pattern which covers the entire screen. GPU artifacts are usually heat related and can often be solved by reducing the GPU temperature. WebCheckerboard patterns have been the most extensively studied and used in clinical testing. Bar and sinusoidal grating stimuli also produce clinically useful responses. Sinusoidal grating stimuli have been reported to be less affected by refractive errors than checkerboard stimuli. If these are used, the vertical or horizontal orientation
