Abstract
With the widespread application of CMOS image sensors, image noise has become an important factor affecting image quality, especially in low light or high ISO environments. As the key to improving image quality, noise suppression technology has become an important research direction in the field of image processing. Traditional noise suppression algorithms use filtering methods to smooth images. Although they can reduce noise to a certain extent, they often lead to the loss of image details and have limited processing capabilities for complex noise types. In recent years, noise suppression methods based on deep learning have developed rapidly. Through models such as convolutional neural networks (CNNs), generative adversarial networks (GANs), and autoencoders, deep learning can more accurately identify and remove noise while effectively retaining image details, showing superior denoising performance than traditional methods. Although deep learning methods have shown excellent results in noise suppression, they consume large computing resources and have slow training and inference speeds. In summary, the application of deep learning in noise suppression has made significant progress and is playing an increasingly important role in image sensor technology.
