“…The combined result is the contourlet filter bank. The contourlet coefficients have a similarity with wavelet coefficients since most of them are almost zero and only few of them, located near the edge of the objects, have large magnitudes [9]. In this work, the Cohen and Daubechies 9-7 filters [10] have been utilized for the Laplacian Pyramid.…”

“…The combined result is the contourlet filter bank, which is a double iterated filter bank that decomposes images into directional subbands at multiple scales. The contourlet coefficients have a similarity with wavelet coefficients since most of them are almost zero and only few of them, located near the edge of the objects, have large magnitudes [10]. In the presented algorithm, the Cohen and Daubechies 9-7 filters [11] have been utilized for the Laplacian Pyramid.…”

“…The combined result is the contourlet filter bank, which is a double iterated filter bank that decomposes images into directional subbands at multiple scales. Moreover, the Contourlet Transform coefficients have a similarity with wavelet coefficients since most of them are almost zero and only few of them, located near the edge of the objects, have large magnitudes [142]. Figure 3.9 shows an example of decomposition using the Contourlet Transform.…”

“…Moreover, this scheme provides enhanced compression due to the downsampling of the lowpass component at each scale.The energy distribution of the Contourlet Transform coefficients is similar to those of the Wavelet Transform, i.e. most of them are near zero except those located near the edges of objects inside the image[265]. Although the Contourlet Transform is considered as an over-complete transform that introduces data redundancy, it provides sub-bands with comparable or better sparseness with respect to the Wavelet Transform, as shown in Figure6.7, making it suitable for compression.…”
