A Novel Adaptive Local Contrast Stretching Guided by Grunwald-Letnikov Fractional Response Field for Enhancing Low-Contrast Simulated Medical Images

2026-08-03

Abstract excerpt

Low contrast is a critical factor that compromises the clinical diagnostic value of medical images such as computed tomography (CT) and magnetic resonance imaging (MRI). Existing enhancement methods either rely on global grayscale remapping while neglecting spatial structural information (e.g., histogram equalization), or employ fixed-parameter adaptive strategies that fail to respond to variations in local anatom...
