Disparity compensation prediction and transform coding are incorporated into a hybrid coding to reduce the bit-rate of multi-view images. However, aliasing and inaccurate displacement impair the performance of disparity compensation, especially in wavelet domain. In this paper, we propose a level-bylevel adaptive disparity compensated prediction scheme for scalable stereo image coding. To get spatial scalable feature, wavelet transform is first applied to the target image of a stereo image pair. A separable 2-D filter applied to the reference image is optimized for each resolution layer by minimizing the energy of the prediction high-bands of the target image. To form a multi-resolution representation, similar processes are then applied to the low-band image pairs generated by the prior resolution layer iteratively. Experimental results show that the proposed scheme can provide significant coding gain compared to other scalable coding scheme.

“…Due to the high efficiency, CALIC has been extended to the lossless compression of multi-spectral image and video [6][7][8]. Although there are a lot of literatures about stereo image compression technology [9][10][11][12][13], few lossless coding method about stereoscopic images are proposed so far. It's beyond question that the research about lossless coding of stereoscopic images is significant, especially in the field of photogrammetry.…”

There exists very high correlation between left-view images and right-view images of stereo image pairs. The correlation can help to reduce the stereoscopic image coding bit rate. Proposed methods first estimate the disparity by using causal neighborhood pixels. And then a prediction method which combines inter-view prediction with intra-view prediction is used to obtain a better predictive coding method for target-view images. The reference-view images are then encoded by using those commonly used prediction coding method. The experimental results show that compared with those methods using only intra-view correlation, the proposed method can obtain lower code rate.

“…With the introduction of discrete wavelet transform ͑DWT͒-based technology for coding still images ͑e.g., EZW, SPIHT, EBCOT, JPEG2000͒ and its use within I-frame coding of MPEG-4, application of DWT technology to stereoscopic image [4][5][6] and sequence 7 coding has recently attracted some research interest. In Ref.…”
