Multistage combined image enhancement technique
Mandar D. Sontakke, Meghana S. Kulkarni · 2016
Image denoising techniques developed so far, have shown successful noise reduction results. As far as the results are considered, noise contents are only targeted to show that denoising is successful. After denoising most of the time as most pixel values are approximated to their neighboring pixels for denoising, image sharpness and appearance is altered up to considerable extent. Hence after denoising if image enhancement in terms of its resolution is required, then obtained results can show that quality is enhanced and quality is up to nearer to noiseless image even after noise reduction from noisy image. This paper indicates the combined approach of denoising and resolution enhancement followed by existing retinex technique for better presentation quality of image. The results obtained show that quality is better in terms of PSNR.
