HSI based colour image equalization using iterative nth root and nth power
This is an incremental improvement for image processing applications, enhancing color image quality.
The paper tackled color image equalization by introducing an nth root and nth power method optimized for mean in RGB and HSI channels, resulting in improved performance over conventional histogram equalization as shown by higher peak signal-to-noise ratio.
In this paper an equalization technique for colour images is introduced. The method is based on nth root and nth power equalization approach but with optimization of the mean of the image in different colour channels such as RGB and HSI. The performance of the proposed method has been measured by the means of peak signal to noise ratio. The proposed algorithm has been compared with conventional histogram equalization and the visual and quantitative experimental results are showing that the proposed method over perform the histogram equalization.
