Synthetic sequences with the moving rectangle filtered via the NVCA algorithm by considering the noise parameters estimates reported in Table 2. The images in each row were obtained by using the noise parameters in the corresponding row of Table 2. On the first column the end frames of the sub-optimal filtered sequences were depicted, while the differences of the same images with the end frame of the optimal filtered sequence were reported on the second column
