![]() ![]() ![]() How can we denoise images containing blind noise? Objective and Constraints Traditional filters fail to perform well on images with such noise. Such noise on real images is called Real-noise or Blind-noise. However, in practice, the noise on real images can be much more complex. Traditional image denoising algorithms always assume the noise to be homogeneous Gaussian distributed. To understand more about noise, check out this blog. Mathematically, noise in an image can be represented by, It is degradation in image signal caused by external sources. Image noise is a random variation of brightness or color information in the images captured. Deep Learning Models for Image Denoising.An Overview on Traditional Filters for Image Denoising.In this blog, I will explain my approach step-by-step as a case study, starting from the problem formulation to implementing the state-of-the-art deep learning models, and then finally see the results. As a result, I have implemented several deep learning architectures that far surpass the traditional denoising filters. There has to be a better way to solve this problem. And if the image is too noisy, then the resultant image would be so blurry that most of the critical details in the image are lost. However, applying those filters would add a blur to the image. They used to work fairly well for images with a reasonable level of noise. In earlier times, researchers used filters to reduce the noise in the images.
