Fractal dimensions have been widely utilized as analytical tools in image processing due to their potential to uncover intricate patterns. This study introduces a novel multiscale fractal dimension (MFD), derived from the characteristic function (CF), which exhibits unique properties, including self-similarity. One significant aspect of image processing research involves the effective reduction of noise, which can interfere with image clarity during transmission. Noise in images poses challenges to their utilization across various applications. In recent years, the strategy of decreasing noise in multiplicative pictures (DNM) has been extensively adopted by researchers to tackle this issue. In this context, the newly proposed MFD is applied to DNM as an innovative method for enhancing image quality. Preliminary results indicate the proposed approach's efficacy, thereby suggesting its potential utility in advanced image processing applications.
