Fuzzy-Based Global-Local Image Enhancement for Contrast and Brightness Preserving

Problem Definition

Problem Description: One common problem faced in the field of image enhancement is the difficulty in simultaneously enhancing the contrast and brightness of an image without losing important details or introducing unwanted artifacts. Existing techniques often focus on either contrast enhancement or brightness preservation individually, resulting in suboptimal results. The challenge lies in finding a technique that can effectively enhance the contrast of an image while preserving its overall brightness levels. Traditional methods may produce images that are either too dark or too bright, making it difficult for viewers to perceive the details in the image accurately. To address this problem, a novel approach utilizing fuzzy inference system and global-local image enhancement techniques can be developed.

By analyzing the HSI color model and extracting the Hue, Saturation, and Intensity components of the image, a more nuanced approach to contrast enhancement and brightness preservation can be achieved. This approach can offer a more balanced enhancement of image quality, leading to improved detail variance and background variance metrics in the evaluation of image enhancement techniques.
