Towards an Evaluation of Denoising Algorithms with Respect to Realistic Camera Noise
2013
2013 IEEE International Symposium on Multimedia
Preserved Fulltext
In this paper, we therefore propose an approach to evaluate denoising algorithms with respect to realistic camera noise: we describe a new camera noise model that includes the full processing chain of ...
Quality metrics, which are required to compare denoising results, are applied, and we evaluate the performance of 10 fullreference metrics and one no-reference metric with our realistic test data. ...

We propose an end-to-end differentiable architecture that jointly performs demosaicking, denoising, deblurring, tone-mapping, and classification. ...
For example, today's demosaicking and denoising algorithms are designed using perceptual image quality metrics but not with domain-specific tasks such as object detection in mind. ...
