"BBHE Histogram Approach for Dull Image Enhancement"

Problem Definition

Problem Description: Despite the advancements in digital image processing techniques, there are still challenges in enhancing dull images without compromising the original brightness. Traditional image enhancement methods may not effectively improve the quality of dull images without causing overexposure or loss of details. This leads to limitations in using enhanced images for specific applications where clarity and brightness are essential. Therefore, there is a need for an image enhancement approach that can effectively improve the quality of dull images while preserving the original brightness to a great extent. The existing histogram equalization techniques may not be sufficient to address this specific requirement.

As a result, there is a demand for a more efficient and effective image enhancement technique that focuses on enhancing the contrast of dull images without altering the mean brightness significantly. The proposed project titled "Dull image enhancement approach using BBHE histogram approach" aims to address this problem by utilizing the BBHE technique to enhance the quality of dull images while preserving the mean brightness. By decomposing the input image based on its mean and independently equalizing histograms over two sub-images, the BBHE technique can effectively improve the dynamic range of dull images without causing overexposure or loss of details. This project will provide a MATLAB-based solution for enhancing dull images using the BBHE technique, offering a more efficient and reliable method for image enhancement.

Proposed Work

Image enhancement is a crucial aspect of digital image processing, aiming to improve the quality of images by enhancing specific features such as brightness and color. Various techniques are used for this purpose, with the BBHE (Bright and Dark pixel based on Histogram Equalization) approach being utilized in this project. The BBHE technique involves calculating the histogram of the image to preserve its original brightness to a great extent. By decomposing the input image based on its mean, the BBHE algorithm independently equalizes histograms of two sub-images, effectively enhancing the image's contrast while maintaining its mean brightness. This MATLAB-based project focuses on utilizing the BBHE technique to enhance image quality, providing a simple and efficient method for image enhancement.

This project falls under the Image Processing & Computer Vision category, specifically in the subcategories of Histogram Equalization and Image Enhancement, making it a noteworthy addition to the latest MATLAB-based projects in the field. The implementation of the Relay Driver (Auto Electro Switching) using ULN-20 module ensures efficient functioning of the BBHE approach for image enhancement.
