Fuzzy Transform for Low-contrast Image Enhancement

摘要

Fuzzy Transform (FT) is becoming popular in the field of image processing applications. This paper presents a novel low contrast image enhancement algorithm using parametric Fuzzy Transform (pFT). To enhance the contrast of poor quality images, initially we generate the fuzzy components of the original image using parametric fuzzy partitions and then they are modified by simple fuzzy probabilistic operators. Experimental results demonstrate that the proposed method outperforms the state-of-art techniques, such as traditional histogram equalization and adaptive histogram equalization in terms of qualitative and quantitative evaluation.
