As the contents of videos vary substantially, the performances of a fully automatic conversion technique are usually limited. It is therefore important to develop efficient semi-automatic techniques to ensure good conversion qualities. The purpose of this thesis is to build a video analysis system which is suitable to be adopted in prior to the 2D to 3D conversion processes. The system aims to automatically summarize the videos in order to relief the manual cost during the 2D to 3D conversion processes, and possibly to facilitate the depth assignment. Firstly, a shot boundary detection method is proposed for the video analysis system to parse a video into basic unit of shot. Based on a novel structure-aware histogram scheme and an adaptive double-threshold scheme, the proposed algorithm achieves improvement upon the conventional methods. The structure-aware scheme effectively integrates the structural similarity measure and local color histogram and hence significantly reduces the false alarms due to motions disturbances. The adaptive double-threshold scheme makes the algorithm effective in detecting mixing types of shot boundaries. Once a video has been detached into shots, keyframes of the shots are further summarized by gathering together those with similar contents. By modeling the keyframes as an undirected graph, the normalized cuts algorithm is employed to recursively partition the graph into clusters. Secondly, camera motion estimation is performed to examine the motion modality of the camera capturing this video shot. As the SfM method for 3D reconstruction is generally restricted to be applied to videos containing translational camera motions, this part of work contributes to the automatically identification of the videos falling in the regime of the SfM method. The camera estimation algorithm utilizes matched features and epipolar geometry constraints to incrementally compute the camera parameters for different views. Based on the camera estimation results, we proposed a method to further explore the distinguishable properties of the sequences taken by translational moving camera. Consequently, the motion modality of the camera can be identified to ensure that the video shots are suitable for the SfM method. Last but not the least, a semantic scene analysis approach which can simultaneously segment and recognize the objects contained in a scene is proposed. The proposed method contains a two-layer random forests (RF) framework. In the first layer, RF effectively labels the image by assigning object classes to superpixels. The structured RF in the second layer predicts local labels together with reliability scores to be aggregated with the initial labeling results. The proposed method achieves higher accuracy because some of the inaccuracy segmentations and implausible labeling problems have been remedied in the second layer. The semantic analysis method can be used to differentiate the immotile background regions and the motile moving objects to assist depth propagation from keyframes. In this way, the semantic scene analysis approach can facilitate the depth propagation from keyframes obtained say from a user interface.

Book excerpt: If you can use a mouse, you can do this. Whether you want to make a simple 3D out of an old 2D, or if you want to create conversions of great paintings, the technique is included. Nothing else approaches this manual in clarity, simplicity, and completeness of coverage. You will be making your own 2D to 3D conversions after reading the first chapter. Four proven techniques, using just your image editor, are included. 1. Starting with fast and easy faux 3D, you will quickly understand every step of the conversion process. Everyone can use this method to add excitement to existing 3D images, to salvage images with defects, or to convert 2D images to 3D's. 2. Then, a complete step-by-step tutorial takes the mystery out of the layer selection and shift method. This is the most precise and reliable method known, capable of creating perfect results from even the most complex images. 3. Also included is the BLAZING FAST depth mapping method to convert 2D images directly to either anaglyph or stereo pairs using the displacement mapping function in Photoshop and other image editors. 4. The simple and instant direct conversion method. With this method you can watch the 3D develop as you work. A 2D image will begin to turn into 3D almost as quickly as you can load the image and begin to work. This on-the-fly method is very intuitive and allows you to experiment without risk of losing your work.

Download or read book 3D TV System with Depth Image Based Rendering written by Ce Zhu and published by Springer Science & Business Media. This book was released on 2012-08-15 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: Riding on the success of 3D cinema blockbusters and advances in stereoscopic display technology, 3D video applications have gathered momentum in recent years. 3D-TV System with Depth-Image-Based Rendering: Architectures, Techniques and Challenges surveys depth-image-based 3D-TV systems, which are expected to be put into applications in the near future. Depth-image-based rendering (DIBR) significantly enhances the 3D visual experience compared to stereoscopic systems currently in use. DIBR techniques make it possible to generate additional viewpoints using 3D warping techniques to adjust the perceived depth of stereoscopic videos and provide for auto-stereoscopic displays that do not require glasses for viewing the 3D image. The material includes a technical review and literature survey of components and complete systems, solutions for technical issues, and implementation of prototypes. The book is organized into four sections: System Overview, Content Generation, Data Compression and Transmission, and 3D Visualization and Quality Assessment. This book will benefit researchers, developers, engineers, and innovators, as well as advanced undergraduate and graduate students working in relevant areas.

Book excerpt: While 3D vision has existed for many years, the use of 3D cameras and video-based modeling by the film industry has induced an explosion of interest for 3D acquisition technology, 3D content and 3D displays. As such, 3D video has become one of the new technology trends of this century. The chapters in this book cover a large spectrum of areas connected to 3D video, which are presented both theoretically and technologically, while taking into account both physiological and perceptual aspects. Stepping away from traditional 3D vision, the authors, all currently involved in these areas, provide the necessary elements for understanding the underlying computer-based science of these technologies. They consider applications and perspectives previously unexplored due to technological limitations. This book guides the reader through the production process of 3D videos; from acquisition, through data treatment and representation, to 3D diffusion. Several types of camera systems are considered (multiscopic or multiview) which lead to different acquisition, modeling and storage-rendering solutions. The application of these systems is also discussed to illustrate varying performance benefits, making this book suitable for students, academics, and also those involved in the film industry.

Book excerpt: Author Joseph Ashley explains video astronomy's many benefits in this comprehensive reference guide for amateurs. Video astronomy offers a wonderful way to see objects in far greater detail than is possible through an eyepiece, and the ability to use the modern, entry-level video camera to image deep space objects is a wonderful development for urban astronomers in particular, as it helps sidestep the issue of light pollution. The author addresses both the positive attributes of these cameras for deep space imaging as well as the limitations, such as amp glow. The equipment needed for imaging as well as how it is configured is identified with hook-up diagrams and photographs. Imaging techniques are discussed together with image processing (stacking and image enhancement). Video astronomy has evolved to offer great results and great ease of use, and both novices and more experienced amateurs can use this book to find the set-up that works best for them. Flexible and portable, they open up a whole new way of seeing space.
