Fig. 14From: High-order balanced M-band multiwavelet packet transform-based remote sensing image denoisingClose-ups of the same part of the noisy image (a) and relevant denoising results (b–e). The area covered is that shown in Fig. 13a. The districts surrounded by red (regions 1 and 2) and yellow (regions 3 and 4) rectangles are selected as homogeneous and heterogeneous regions for ENL calculation, respectivelyBack to article page
