Image Enhancement using Fuzzy Intensity Measure and Adaptive Clipping Histogram Equalization
This addresses image enhancement for applications requiring visual quality, but it is incremental as it builds on existing histogram equalization techniques.
The paper tackled the problem of noise and distortion in histogram equalization for image enhancement by proposing FIMHE, which uses fuzzy intensity measure and adaptive clipping, and showed it outperforms state-of-the-art methods on Berkeley and CVF-UGR-Image databases.
Image enhancement aims at processing an input image so that the visual content of the output image is more pleasing or more useful for certain applications. Although histogram equalization is widely used in image enhancement due to its simplicity and effectiveness, it changes the mean brightness of the enhanced image and introduces a high level of noise and distortion. To address these problems, this paper proposes image enhancement using fuzzy intensity measure and adaptive clipping histogram equalization (FIMHE). FIMHE uses fuzzy intensity measure to first segment the histogram of the original image, and then clip the histogram adaptively in order to prevent excessive image enhancement. Experiments on the Berkeley database and CVF-UGR-Image database show that FIMHE outperforms state-of-the-art histogram equalization based methods.
