2 B. Ning et al. / Journal of Computational and Applied Mathematics 195 (2006) coding, quad-tree partitioning (QTP) and embedded block coding with optimized truncation (EBCOT) [9] are widely used, while the latter is adopted in JPEG2000. In recent years, multiband wavelets [1,8] have been effectively used in many areas, such as texture segmentation for real-life image analysis [3], context-based classification in document image [4], and palmprint recognition [2]. In this paper, we introduce a new family of multiband wavelets and apply them to image coding. 2. Structure of algorithm The structure of our adaptive algorithm is as follows: (i) the size of band M (for instance M = 4, 8or 16) is chosen according to the size of the image; (ii) the parameter λ and the significant bands among high-frequency subbands are determined by the significance rule; (iii) a significant subband is further partitioned into blocks according to QTP; and (iv) an important block is introduced and the coefficients in important blocks are quantized by bit-plane, and arithmetic coding is used to form an embedded bitstream, while unimportant blocks are coded with one-bit data only. 3. Decomposition and reconstruction of multiband wavelets Based on multiresolution analysis, Mallat [5] introduced a pyramid algorithm for a two-band wavelet. Similarly, we have a pyramid algorithm for multiband wavelets [8]. Let M be an integer greater than two, and H j, 1 j M be Laurent polynomials satisfying: H 1 (1) = 1, H j (1) = 0 for all 2 j M, and M 1 l=0 H i(zw l )H j (z 1 W l ) = δ ij for all 1 i, j M and z = 0, where W = exp( 2πi/M) is the usual Mth unit root. The templates of filter H ij (x, y), 1 i, j M, are defined by H ij (x, y) = H i (x)h j (y), 1 i, j M. By multiband wavelet decomposition, an image is divided into M M subbands via M M channels (see Fig. 1 for M = 4). In this paper, we choose M = 4 and the Laurent polynomials for a filter template H11 H12 H13 H14 H21 H22 H23 H24 H31 H32 H33 H34 H41 H42 H43 H44 Fig. 1. Decomposition with a four-band wavelet.

3 4 B. Ning et al. / Journal of Computational and Applied Mathematics 195 (2006) 2 7 as follows: H 1 (z) = λ 1 (1 + z 7 ) + λ 4 (z + z 6 ) + λ 3 (z 2 + z 5 ) + λ 2 (z 3 + z 4 ), H 2 (z) = λ 4 (1 z 7 ) λ 1 (z z 6 ) + λ 2 (z 2 z 5 ) + λ 3 (z 3 z 4 ), H 3 (z) = λ 4 (1 + z 7 ) + λ 1 (z + z 6 ) + λ 2 (z 2 + z 5 ) λ 3 (z 3 + z 4 ), H 4 (z) = λ 1 (1 z 7 ) λ 4 (z z 6 ) + λ 3 (z 2 z 5 ) λ 2 (z 3 z 4 ), where λ 1 = 1 4 (1 + 2 cos λ), λ 2 = 1 4 (1 2 cos λ), λ 3 = 1 4 (1 + 2 sin λ), λ 4 = 1 4 (1 2 sin λ), and the parameter λ varies from 0 to 2π. We remark that the above multiband wavelet filters become usual four-band Haar wavelet filters when λ = 0.75π, and multiband wavelet filters in [3] when λ = π. In most image coding, we are required to store images with minimal storage and minimal (visual) distortion. For an image, the part with less visual distortion usually has a high frequency and contains certain directional information. So a decomposition of an image with each part having different frequency and directional information could be convenient for image coding. A multiband wavelet decomposition is such a decomposition. In particular, after taking a multiband wavelet decomposition with dilation M, an image is decomposed into one subband with a lower frequency and M 2 1 subbands with a high frequency, and each subband reflects different frequency and directional features of the image. We introduce a family of a four-band wavelet decomposition with parameter λ, and observe that the frequency width of each subband in the wavelet decomposition varies according to different parameters λ. Thus, for a given image, optimization of parameter λ in the four-band wavelet decomposition leads to a better image coding. 4. Encoding steps Step 1: Significance rule. For a given image, we observe that the intensity contrast of texture in high-frequency subbands is not similar to each other when wavelet filters with different parameters λ are applied (see Fig. 2). For a better Fig. 2. Different results under four-band wavelet decomposition with different parameters. From left to right: (a) λ = 0.75π, (b) λ = 0.855π and (c) λ = 0.1π.

4 B. Ning et al. / Journal of Computational and Applied Mathematics 195 (2006) PSNR rate, we introduce the following significance rule: N X N Y 1 i=0 (A i Min)>k Aver, (1) where A i is the ith wavelet coefficient, N X and N Y are the width and height of the corresponding subband, Min is the minimal coefficient in that subband, k is a constant (here, we use k = 4), and Aver = NX N Y 1 i=0 A i N X N Y. (2) A given subband is said to be significant if rule (1) holds true, and insignificant otherwise. Step 2: Important blocks. To increase the compression rate, we introduce a new concept, an important block, which is defined by the following importance rule (3) ( (Ai ) X) 2 1/2 >g, (3) N W N H where A i are wavelet coefficients in that block, N W and N H are the width and height of that block, g is a threshold, and X is the mean of the block. Step 3: Adaptive subband selection and QTP algorithm. Performing a multiband wavelet decomposition of a given image, we obtain M M subbands. If a subband is insignificant, we omit that subband and code it in 1 bit. If a subband is significant, besides the lowest frequency subband, we further divide it into blocks with QTP, and determine whether the resulting subblocks are important blocks or not. If a subblock is not an important subblock, we regard the coefficients of that subblock as zeros and then code them accordingly. If that subblock is an important subblock, we store that subblock and code it further. The above adaptive algorithm by selecting significant subbands and important blocks works well in our experiment; see Figs. 3 and 4 for the encoded Barbara image. Fig. 3. Encoding with an adaptive subband. From left to right: (a) Original Barbara image, (b)encoded image.

EZW coding with two-band wavelet transform and our adaptive encoding algorithm. From left to right for each row: (a) Original texture image taken from Brodatz Textures; (b) Encoding under five-level wavelet decomposition (0.25 bpp); (c) Encoding with our adaptive encoding algorithm. 5. Experimental results and conclusion In our experiment, we use Barbara, Goldhill and some texture images, and compare our adaptive encoding algorithm with EZW coding under the PSNR (see Fig. 5 for the encoded texture images using EZW coding and our adaptive encoding algorithm, and Table 1 for the PSNR result). Our experiment shows that for those images having rich textures, such as Barbara, Goldhill or texture images, our adaptive encoding algorithm based on multiband wavelet performs better than the widely used EZW method. Also, our encoding scheme has the following advantages: (i) no error stacked by a multiband wavelet transform, because we deal with data on an original image directly instead of multi-level decomposition, and hence the host image can be preserved well; (ii) less information loss; (iii) simple structure of the algorithm; and (iv) ROI (region of interest) coding and embedded coding applicable.
