Estimation of Optimum Noise Intensity for Memory Texture Feeling Reconstruction Based on Fractal Dimension

Abstract

It has been known that the feeling on the texture surface can be improved by adding Gaussian noise to a given original image. It is laborious to determine the appropriate noise intensity for the texture feeling by subjective evaluation experiments with many raters. In this paper, the objective estimation method of the appropriate noise intensity to reconstruct the optimum memory texture feeling is proposed based on fractal dimension using a set of noisy images. It is seen in the experimental results using the paired comparison method that the estimated noise intensity by our method can improve the memory texture feeling compared with other noise intensities.
