Implementation of 2D Discrete Wavelet Transform by Number Theoretic Transform and 2D Overlap-Save Method
Figure 8
The linear outputs of 2D overlap-save method: (a) the outputs of the linear convolution of each subimages, (b) the left border and the upper border of the outputs of the image of aircraft, (c) the combined outputs of linear convolution, except -type border, and (d) the entire contour extracted using 2D overlap-save method under wavelet transform.
