In this paper, we propose a new stereo image compression scheme that is based on the wavelet transform of both images and the disparity estimation between the stereo pair subbands. The two images are decomposed by using a Discrete Wavelet Transform (DWT) and coded by employing the morphological representation of the wavelet coefficients, which is a(More)
In this paper, we propose a family of novel stereoscopic image coders based on morphological coding and a block-based disparity compensation algorithm. The proposed schemes employ Discrete Wavelet Transform (DWT) decomposition and a morphological coder that lowers total entropy by exploiting the intra-band and inter-band statistical properties of the(More)
In this paper, we propose a novel stereoscopic image coder, which consists of a coding unit based on the morphological representation of the wavelet transform coefficients and a disparity compensation unit based on the quad-tree analysis and the disparity compensation between the images of a stereo pair. The coding unit employs a Discrete Wavelet Transform(More)
This paper presents a stereoscopic image coder based on the MRF model and MAP estimation of the disparity field. The MRF model minimizes the noise of disparity compensation, because it takes into account the residual energy, smoothness constraints on the disparity field, and the occlusion field. Disparity compensation is formulated as an MAP-MRF problem in(More)
