| Summary: | This study presents a Convolutional Neural
Network (CNN) model to effectively recognize the presence of
Gaussian noise and its level in images. The existing denoising
approaches are mostly based on an assumption that the images to
be processed are corrupted with noises. This work, on the other
hand, aims to intelligently evaluate if an image is corrupted, and
to which level it is degraded, before applying denoising
algorithms. We used 12000 and 3000 standard test images for
training and testing purposes, respectively. Different noise levels
are introduced to these images. The overall accuracy of 74.7% in
classifying 10 classes of noise levels are obtained. Our
experiments and results have proven that this model is capable of
performing Gaussian noise detection and its noise level
classification.
