waifu2x is an image scaling and noise reduction program for anime-style art and other types of photos. [ 1] waifu2x was inspired by Super-Resolution Convolutional Neural Network (SRCNN). [ 2][ 3] It uses Nvidia CUDA for computing, [ 4] although alternative implementations that allow for OpenCL [ 5] and Vulkan [ 6] have been created.
StyleGAN. An image generated using StyleGAN that looks like a portrait of a young woman. This image was generated by an artificial neural network based on an analysis of a large number of photographs. StyleGAN is a generative adversarial network (GAN) introduced by Nvidia researchers in December 2018, [ 1] and made source available in February ...
This example created using demo_tv.m by Guy Gilboa, see external links. In signal processing, particularly image processing, total variation denoising, also known as total variation regularization or total variation filtering, is a noise removal process ( filter ). It is based on the principle that signals with excessive and possibly spurious ...
Tegra, a system on a chip series for mobile devices. Tesla, line of dedicated general-purpose GPUs for high-end image generation applications in professional and scientific fields. nForce, a motherboard chipset created by Nvidia for Intel (Celeron, Pentium and Core 2) and AMD (Athlon and Duron) microprocessors.
Support status. Supported. Ada Lovelace, also referred to simply as Lovelace, [ 1] is a graphics processing unit (GPU) microarchitecture developed by Nvidia as the successor to the Ampere architecture, officially announced on September 20, 2022. It is named after the English mathematician Ada Lovelace, [ 2] one of the first computer programmers.
Noise reduction. Noise reduction is the process of removing noise from a signal. Noise reduction techniques exist for audio and images. Noise reduction algorithms may distort the signal to some degree. Noise rejection is the ability of a circuit to isolate an undesired signal component from the desired signal component, as with common-mode ...
Image noise. Image noise is random variation of brightness or color information in images, and is usually an aspect of electronic noise. It can be produced by the image sensor and circuitry of a scanner or digital camera. Image noise can also originate in film grain and in the unavoidable shot noise of an ideal photon detector. Image noise is ...
A dark frame is an image captured with the sensor in complete darkness (i.e. with a closed shutter or the lens and viewfinder capped). Such a dark frame is essentially an image of noise produced by the sensor. A dark frame, or an average of several dark frames, can then be subtracted from subsequent images to correct for fixed-pattern noise.
