This study concludes that, with moderate noise, demosaicing should be applied first, followed by denoising, and discovers that for high noise, there is a moderate PSNR gain by a more complex strategy: partial CFA denoising followed by demosaicing, and by a second denoising on the RGB image.

It is proved that the best way to reconstruct full color images from a noisy mosaic requires an adaptation of classic denoising algorithms to demosaicked noise, which is justified and specify.

This paper proposes and explores a way to transform CFA data to a form that is amenable to existing grayscale and color denoising schemes, and can expect to reduce processing time and power requirements to about a third of current requirements.

This paper proposes a systematic procedure for estimating ground truth for noisy images that can be used to benchmark denoising performance for smartphone cameras and shows that CNN-based methods perform better when trained on the authors' high-quality dataset than when trained using alternative strategies, such as low-ISO images used as a proxy for ground truth data.

A new data-driven approach forDemosaicking and denoising is introduced: a deep neural network is trained on a large corpus of images instead of using hand-tuned filters and this network and training procedure outperform state-of-the-art both on noisy and noise-free data.

Experimental results demonstrate that the proposed local directional interpolation and nonlocal adaptive thresh- olding method outperforms many state-of-the-art CDM methods in reconstructing the edges and reducing color interpolation artifacts, leading to higher visual quality of reproduced color images.

The solution, which improves preservation of details in the NR filtering before the CFAI, is proposed, and is based on the quality of the output image, the processing power requirements and the amount of memory needed.
