The arrival, and continuing evolution, of high quality 3D objectshas been made possible by recent progress in 3D scanner acquisitionand 3D graphics rendering. With this increasingquality comes a corresponding increase in the size and complexityof the data files and the necessity for advances in compressiontechniques. Effective indexing to facilitate the retrieval of the3D data is then required to efficiently store, search and recapturethe objects that have been compressed. The application of 3D imagesin fields such as communications, medicine and the military alsocalls for copyright protection, or watermarking, to secure the datafor transmission.
Written by expert contributors, this timely text brings togetherthe three important and complementary topics of compression,retrieval and watermarking techniques for 3D objects. 3Dobject processing applications are developing rapidly and this booktackles the challenges and opportunities presented, focusing on thesecure transmission, sharing and searching of 3D objects onnetworks, and includes:
* an introduction to the commonly used 3D representation schemes;the characteristics, advantages and limitations of polygonalmeshes, surface based models and volumetric models;
* 3D compression techniques; the 3D coding and decoding schemesfor reducing the size of 3D data to reduce transmission time andminimize distortion;
* state of the art responses to the intrinsic challenges ofbuilding a 3D-model search engine, considering view-based,structural and full-3D approaches;
* watermarking techniques for ensuring intellectualproperty protection and content security without altering thevisual quality of the 3D object.
3D Object Processing: Compression, Indexing andWatermarking is an invaluable resource for graduate studentsand researchers working in signal and image processing, computeraided design, animation and imaging systems. Practising engineerswho want to expand their knowledge of 3D video objects, includingdata compression, indexing, security, and copyrighting ofinformation, will also find this book of great use.
