Optimizing Image Denoising using CNN and Bilateral Filter in MATLAB

Problem Definition

Image denoising is a critical task in various industries such as medical imaging, security, and photography, as it is essential to enhance the clarity and quality of images by removing unwanted noise. However, despite advancements in artificial intelligence and image processing techniques, the process of denoising still presents significant challenges. The current methods often lack efficiency and effectiveness in accurately preserving image details while reducing noise. This research project aims to address these limitations by utilizing a CNN pre-trained model and a bilateral filter to improve the denoising process. By integrating artificial intelligence into image denoising, the project seeks to develop a system that can achieve better results in noise reduction without compromising the image quality.

One of the key pain points in image denoising is the complexity and difficulty of implementing advanced algorithms for noise reduction. Existing software tools may require users to have a deep understanding of complex algorithms and coding, making it inaccessible to individuals with limited technical knowledge. Hence, the development of a user-friendly GUI interface will be crucial in ensuring that the denoising system can be easily utilized by a broader audience, including individuals without a background in image processing. By simplifying the user interface and integrating sophisticated algorithms into a user-friendly software application, this project aims to democratize the access to efficient image denoising technology.

Algorithms Used

The Convolutional Neural Network (CNN) is utilized, a deep learning algorithm that can take in an input image, assign importance (learnable weights and biases) to various aspects or objects in the image, and differentiate one from the other. In combination with the bilateral filter, a non-linear, edge-preserving, and noise-reducing smoothing filter, the project optimizes image denoising. The proposed work involves creating a MATLAB GUI to interactively allow the use of the image denoising process. The developed system utilizes a Convolutional Neural Network (CNN) pre-trained model and a bilateral filter to denoise an image. Users can select an image from a standard dataset and specify the level of noise in it.

Then, they can run the image through the system that follows a process—adding noise, applying the CNN pre-trained model and bilateral filter—to finally denoise the image. The project also draws upon and enhances an existing base paper on enhancing CNN for image denoising. This forms the basis for further improvements in the system.
