Self-supervised image denoising using a single noisy image without clean targets.

Noise2Void (N2V) is a self-supervised deep learning method for image denoising. It operates on single noisy images, eliminating the need for clean target images or noisy image pairs, enabling its use in scenarios where acquiring training targets is impractical, especially in biomedical imaging. The architecture leverages a modified UNet to reduce checkerboard artifacts, replacing MaxPool layers with BlurPool layers, rolling back the residual-UNet to a non-residual UNet, and eliminating skip connections at the uppermost UNet level. N2V's training scheme involves masking or creating blind spots in the input image and predicting the masked pixel intensities from neighboring pixels. Although N2V cannot outperform methods with more information, its performance compares favorably to training-free denoising approaches. The implementation is based on TensorFlow and has been tested with Python 3.9 and TensorFlow versions 2.7, 2.10, and 2.13.

N2V employs a blind-spot network training strategy where the network predicts the value of a pixel based on its neighbors, ensuring that it doesn't simply copy the input.
The architecture uses BlurPool instead of MaxPool layers throughout the UNet, rolling back the residual-UNet to a non-residual UNet, and eliminating skip connections at the uppermost UNet level.
N2V trains the network on the noisy images themselves by masking pixels and predicting their values from the surrounding context.
N2V is built on TensorFlow, providing access to a wide range of tools and libraries for deep learning.
Employs new replacement strategies to determine the pixel intensity values that fill in the elected blind-spot pixels.
