Adaptive Wavelet Thresholding for Multiresolution Denoising Based on Image Size

Hard thresholding is a common method for denoising wavelet coefficients. However, determining an optimal threshold remains challenging. Therefore, we propose an adaptive hard threshold that accounts for the size of the noisy image based on the statistical properties of the wavelet coefficient. Regre...
