An efficient method for contrast enhancement of real world hyper spectral images

الملخص EN

This paper proposed an efficient method for contrast enhancement of real world hyper spectral images.

The contrast of image is an important characteristic by which the quality of image can be judged as good or poor quality.

The proposed method is consists of two stages: In first stage the poor quality of image is process by automatic contrast adjustment in spatial domain and in second stage the output of first stage is further process by adaptive filtering for image enhancement in frequency domain.

Simulation and experimental results on benchmark real world hyper spectral image database demonstrates that proposed method provides better results as compared to other state-of-art contrast enhancement techniques.

Proposed method performs better in different dark and bright real world hyper spectral images by adjusting their contrast very frequently.

Proposed method is very simple and efficient approach for contrast enhancement of real world hyper spectral images.

This method can be used in different applications where images are suffering from different contrast problems.
