For efficient encoding using 3-D motion information, apart from the 3-D motion parameters, a dense depth field must also be encoded to achieve 2-D motion compensation on the image plane. Inspiring from Rate-Distortion Theory, a novel method is proposed to optimally encode the dense depth fields of the moving objects in the scene. Using two intensity frames and 3-D motion parameters as inputs, an encoded depth field can be obtained by jointly minimizing a distortion criteria and a bit-rate measure. Since the method gives directly an encoded field as an output, it does not require an estimate of the field to be encoded. By efficiently encoding the depth field during the experiments, it is shown that the 3-D motion models can be used in object-based video compression algorithms.EnglishAlgorithmsComputer visionDepth perceptionError analysisImage compressionImage qualityOptical image storageParameter estimationDepth fieldsDistortion criteriaImage framesImage planesTemporal redundancyThree dimensional motion modelsTwo dimensional motion compensationVideo compression algorithmsImage codingConference Paper10.1109/ICIP.1996.561043
