Der volle Inhalt der QuelleWith the rapid growth of multimedia content, 3D objects are becoming more and more popular. Most of the time, they are modeled as complex polygonal meshes or dense point clouds, providing immersive experiences in different industrial and consumer multimedia applications. The point cloud, which is easier to acquire than mesh and is widely applicable, has raised many interests in both the academic and commercial worlds.A point cloud is a set of points with different properties such as their geometrical locations and the associated attributes (e.g., color, material properties, etc.). The number of the points within a point cloud can range from a thousand, to constitute simple 3D objects, up to billions, to realistically represent complex 3D scenes. Such huge amounts of data bring great technological challenges in terms of transmission, processing, and storage of point clouds.In recent years, numerous research works focused their efforts on the compression of meshes, while less was addressed for point clouds. We have identified two main approaches in the literature: a purely geometric one based on octree decomposition, and a hybrid one based on both geometry and video coding. The first approach can provide accurate 3D geometry information but contains weak temporal consistency. The second one can efficiently remove the temporal redundancy yet a decrease of geometrical precision can be observed after the projection. Thus, the tradeoff between compression efficiency and accurate prediction needs to be optimized.We focused on exploring the temporal correlations between dynamic dense point clouds. We proposed different approaches to improve the compression performance of the MPEG (Moving Picture Experts Group) V-PCC (Video-based Point Cloud Compression) test model, which provides state-of-the-art compression on dynamic dense point clouds.First, an octree-based adaptive segmentation is proposed to cluster the points with different motion amplitudes into 3D cubes. Then, motion estimation is applied to these cubes using affine transformation. Gains in terms of rate-distortion (RD) performance have been observed in sequences with relatively low motion amplitudes. However, the cost of building an octree for the dense point cloud remains expensive while the resulting octree structures contain poor temporal consistency for the sequences with higher motion amplitudes.An anatomical structure is then proposed to model the motion of the point clouds representing humanoids more inherently. With the help of 2D pose estimation tools, the motion is estimated from 14 anatomical segments using affine transformation.Moreover, we propose a novel solution for color prediction and discuss the residual coding from prediction. It is shown that instead of encoding redundant texture information, it is more valuable to code the residuals, which leads to a better RD performance.Although our contributions have improved the performances of the V-PCC test models, the temporal compression of dynamic point clouds remains a highly challenging task. Due to the limitations of the current acquisition technology, the acquired point clouds can be noisy in both geometry and attribute domains, which makes it challenging to achieve accurate motion estimation. In future studies, the technologies used for 3D meshes may be exploited and adapted to provide temporal-consistent connectivity information between dynamic 3D point clouds

Recently, the applications for the combination of virtual reality and multimedia technique are popular, such as the architectural walkthroughs. For these 3D (three dimension) geometry objects, they almost are large datasets. However, the performance of transmission is not satisfactory due to the limitation of bandwidth of current networks. In addition, the real-time graphics hardware is facing a large memory bus bandwidth bottleneck in which the amount of 3D geometry objects cannot be sent fast enough to the graphics pipeline interface. Base on the above reasons, if these geometry objects can be transmitted on networks in compressed format, the transmission time will be reduced greatly. Similarly, the geometry object can be stored in main memory in compressed format. Upon rendering in graphics pipeline interface, the compressed geometry data is sent to the rendering hardware for real-time decompression using an efficient hardware decompressor. Although the geometry compression/decompression technique can solve the memory bus bandwidth bottleneck, the proof of run time is important in real-time qualification. The idea of our algorithm is that one edge can connect to two new vertices to form two contiguous triangles. Furthermore, the idea of homocentric circle is added and these triangles of geometry objects can be represented by the binary tree structure. We can encode the binary tree to linear structure moderately. Such solutions can record the triangle information completely, and less storage space is needed on main memory. We only need a queue to perform the compression and decompression operations. The processes are fast enough for real-time applications. We present the geometry compression/decompression algorithm that has better compression ratios and run time than local meshify algorithm. We have tried our optimized geometry compressor on several datasets. It achieves compression ratios of 12 to 15 times over binary encoded triangle strips. Some geometry objects can achieve up to 18. The Run time of compression operation likes decompression operation, and is fast. Because the compression/decompression algorithm is very simple and less storage space is needed on main memory. These benefits allow a real-time hardware realization of compression/decompression algorithm.
