Abstract
This paper proposed an improved method for contrast enhancement of real world hyperspectral images The proposed method consists of two stages: In first stage the poor quality of image is processed by adaptive histogram equalization in spatial domain and in second stage the output of first stage is further processed by adaptive filtering for image enhancement in frequency domain. Simulation and experimental results on benchmark real world hyperspectral image database demonstrates that proposed method provides better results as compared to other state-of-art contrast enhancement techniques such as alpha rooting (AR), multi contrast enhancement (MCE), multi-contrast enhancement with dynamic range compression (MCEDRC), brightness preserving dynamic fuzzy histogram equalization (BPDFHE). Proposed method performs better for different dark and bright real world hyperspectral images by adjusting their contrast very frequently. Proposed method is simple and efficient approach for contrast enhancement of real world hyperspectral images. This method can be used in different applications where images are suffering from various contrast problems.
