چکیده

Actually to generate a 3D view starting from a single view image different tools are required. These are not fully automatic application and require expensive computational resources. This paper presents a single framework aimed to obtain the stereoscopic view avoiding the user interaction and reducing the computation complexity. Moreover the depth map generation step is able to work directly onto a Bayer pattern image (CFA) further reducing band, memory and complexity requirements. Alternatively a sub sampled image can be used. This proposed technique is based on a novel algorithm [1] able to generate a depth map from a single image. The strength of method [3] is then used to reconstruct the left and right view. The two steps are pipelined so obtaining a single automatic 3D generation procedure. In order to obtain the depth map, an image preprocessing is required. It is composed of the following steps: 1) Image classification ; 2) Vanishing lines and vanishing point extraction. The stereoscopic pair image is then generated by calculating the parallax value ([8], [9], [10], [12]) of each object in the image extracting information only from the grey level depth map. The final left and right eye images give to the user a 3D perspective entertainment. The highlighted process is fully automatic and well suited for real-time application. Effectiveness of the proposed processing pipeline has been validated by an exhaustive set of experiments. This paper is organized as follows: Section 2 resumes the used image classification method describing also the techniques to extract the vanishing lines and the vanishing point. Section 3 explains how the depth map is generated. In section 4 an overview of the Stereoscopic pair image generation is given. Experimental results are reported in Section 5. Section 6 closes the paper tracking directions for future works.

$EVWUDFW Relying fully on manual effort in generating metadata is not the way to go: we need automation of this process, as much as possible, without losing the “quality” of the metadata. In this paper we report on our experiences with automatic metadata generation. We briefly outline the first version of our framework for automatic metadata generation and then report on some lessons we learned...

Virtual humans simulations are becoming each time more popular. Nowadays many systems are available to animate virtual humans. Such systems encompass several different domains as: autonomous agents in virtual environments, human factors analysis, training, education, virtual prototyping, simulation-based design, and entertainment. Virtual humans (see Fig.1) are commonly used nowadays in the ent...

STO: A Danish Lexicon Resource - Ready for Applications

$EVWUDFWW This paper deals with the STO lexicon, the most comprehensive computational lexicon of Danish developed for NLP/HLT applications, which is now ready for use. Danish was one of the 12 EU-languages participating in the LE-PAROLE and SIMPLE projects; therefore it was obvious to continue this work building on our experience obtained from these projects. The material for Danish produced wi...

New product development, based on SOC (System on a Chip) and IP (Intellectual Property) cores, requires, as much as possible, design and test [1]. High design productivity drives the need for test preparation to be carried out as early as possible in the design flow, thus at RTL (Register Transfer Level) [2]. However, RT-level test patterns are not routinely reused for production test, since hi...
