注意

The effect of this method is reduced as per step-by-step procedures mentioned in reference [3]. First, we transform each pixel value using a logarithmic function to address issues with low contrast lighting conditions. After normalization, each pixel has an average value of 0 and unit norm. Finally, we multiply each image by a cosine window whose coefficients decrease smoothly from one at the center to zero at the edges. This approach not only reduces noise but also emphasizes details in central
