Multiple Description Coding Based on Optimized Redundancy Removal for 3D Depth Map
Multiple description (MD) coding is a promising alternative for the robust transmission of information over error-prone channels. In 3D image technology, the depth map represents the distance between the camera and objects in the scene. Using the depth map combined with the existing multiview image, it can be efficient to synthesize images of any virtual viewpoint position, which can display mo...
متن کاملOptimized Multiple Description Scalar Quantization Based 3d Mesh Coding
In this paper, we propose a Multiple Description Coding (MDC) scheme for 3D models represented by triangular meshes. The objective of MDC is to encode a source into multiple bitstreams, called descriptions, supporting multiple quality levels of decoding. The proposed scheme is based on multiresolution geometry compression achieved by usingwavelet transform andmodified SPIHT algorithm. We obtain...
متن کاملFast Intra Mode Decision for Depth Map coding in 3D-HEVC Standard
three dimensional- high efficiency video coding (3D-HEVC) is the expanded version of the latest video compression standard, namely high efficiency video coding (HEVC), which is used to compress 3D videos. 3D videos include texture video and depth map. Since the statistical characteristics of depth maps are different from those of texture videos, new tools have been added to the HEVC standard fo...
متن کاملAnalysis of Depth Map Resampling Filters for Depth-based 3D Video Coding
Depth map images are characterized by large homogeneous areas and strong edges. It has been observed that efficient compression of the depth map is achieved by applying a down-sampling operation prior to encoding. However, since high resolution depth maps are also needed for depth-based 3D coding tools, such as view synthesis prediction, an upsampling method that is able to recover the loss of ...
متن کاملMultiple Description Coding Based on Hadamard Transform
Multiple description coding is one of the coding techniques used in the non-prioritized networks to transmit image. In this coding method, the image is split into two or more descriptions and compressed with a controlled level of redundancy. Because of the introduced controlled redundancy the image can be recovered from the other descriptions. Due to this there is a slight degradation in the re...
