Constructing Stereo Presentations of Textual Information on an Autostereoscopic Monitor

This paper presents practical experience in constructing stereo presentations of texts and formulas on an autostereoscopic monitor in stereo presentations designed to display the results of numerical simulation. The task of constructing stereo images of texts and formulas is a structural subtask of a general study devoted to the development of methods and algorithms for constructing stereo presentations of the results of scientific research. This paper discusses the construction of stereoscopic images on an autostereoscopic monitor. The autostereoscopic monitor allows one to observe a stereo image without glasses, while ensuring the quality of the stereo image, which is not inferior to the quality of the stereo image, presented using a classic 3D projection stereo system. Various methods of obtaining stereo images supported by the monitor were tested, namely, the multi-view presentation of the object and the construction of depth maps. The results for both methods are presented.

Abstract The reversible data hiding allows original image to be completely recovered from the stego image when the secret data has been extracted, it is has drawn a lot of attentions from researchers. In this paper, a novel Taylor Expansion (TE) based stereo image reversible data hiding method is presented. Since the prediction accuracy is essential to the data hiding performance, a novel TE based predictor using correlations of two views of the stereo image is proposed. TE can fully exploit strong relationships between matched pixels in the stereo image so that the accuracy of the prediction can be improved. Then, histogram shifting is utilized to embed data to decrease distortion of stereo images, and multi-level hiding can increase embedding capacity. Experimental results show that the proposed method is superior to some existing data hiding methods considering embedding capacity and the quality of the stego stereo images.

Abstract. Extracting detailed geometric information about a scene relies on the quality of the depth maps (e.g. Digital Elevation Surfaces, DSM) to enhance the performance of 3D model reconstruction. Elevation information from LiDAR is often expensive and hard to obtain. The most common approach to generate depth maps is through multi-view stereo (MVS) methods (e.g. dense stereo image matching). The quality of single depth maps, however, is often prone to noise, outliers, and missing data points due to the quality of the acquired image pairs. A reference multi-view image pair must be noise-free and clear to ensure high-quality depth maps. To avoid such a problem, current researches are headed toward fusing multiple depth maps to recover the shortcomings of single-depth maps resulted from a single pair of multi-view images. Several approaches tackled this problem by merging and fusing depth maps, using probabilistic and deterministic methods, but few discussed how these fused depth maps can be refined through adaptive spatiotemporal analysis algorithms (e.g. spatiotemporal filters). The motivation is to push towards preserving the high precision and detail level of depth maps while optimizing the performance, robustness, and efficiency of the algorithm.

Production Plans

The author analyzes the reasons that objectively reduce the importance and quality of the organizational and technological solutions of work production plans and the content of their main documents. Based on a generalization of practical experience, one of the real ways of increasing the level of work production plans is proposed as a result of the development of "The Unified Rules for Work Production on the Site" as part of the construction organization project, in the form of fundamental requirements, followed by the inclusion of this document in the work production plan as an input document. The structure and content of the Unified Rules are described with the disclosure of the main documents - calendar plans of work, construction master plans, technological schemes of works. The first section of the document contains requirements for the content of tasks for the development of the project of work execution, the order of its approval, and requirements for the quality of solutions. The second section presents principal solutions, methods of work execution and their technological schemes. The organizational and technological solutions adopted in the proposed document are specified and detailed by the General Contractor Construction Organization with due regard for the resource capabilities and the actual conditions of construction or reconstruction.

Critical Constraints

The pressure to publish is a fact of life in academia. Academics are expected to demonstrate that they are active researchersand that their work has been vetted by peers and disseminated in reputable scholarly forums. In practice, however, a numberof critical constraints hamper effective publication of scientific research in most developing countries. These include lackof effective mentoring system, poor facilities and inadequate funding for effective research and heavy workload where toomuch time and effort are spent in teaching, grading, meetings and other non-academic activities. In spite of these seeminglyinsurmountable challenges, with proper planning and commitment, one can still conduct research and publish to advanceones career and exchange of knowledge. The paper discusses the critical guiding principles in scientific writing and publishingin an unfriendly research environment as pertains in most universities in the developing world. The overriding principle isto cultivate the discipline of scientific writing consciously and follow it through religiously. This could be achieved if time isallocated for scientific writing in the scheme of weekly schedule of activities and made to be functional through meticulousplanning and commitment. Equally important is to avoid procedural mistakes in scientific writing. While the quality of theresearch is the single most important factor in determining whether an article will be published, a number of proceduralmistakes can help tip the balance against its publication. It should also be noted that when a manuscript is submitted to ascholarly journal, there are two audiences to satisfy: first the editor and external reviewers, and then the journal’s readers.That first group must be satisfied to create the opportunity to appeal to the second. Thus, familiarity with the style and tone ofthe specific journal is crucial.

Education In India

Quality, as we know so far, was originally developed in the manufacturing industry. In the area of higher education, the adoption of quality control has been superficial and diluted by the exercise of academic . Further, the prevailing culture of universities is often based on individual autonomy, which is zealously guarded. Thus, it is usually difficult to apply the features of quality to higher education considering the fact that quality requires. However, the quality of higher education is very important for its stakeholders. Notably, providers (funding bodies and the community at large), students, staff and employers of graduates are. The most commonly grouped dimensions of quality are product, software and service. In the changing context marked by expansion of higher education and globalization of economic activities, education has become a national concern with an international dimension. To cope with this changing context, countries have been pressurized to ensure and assure quality of higher education at a nationally comparable and internationally acceptable standard. Consequently, many countries initiated “national quality assurance mechanisms” and many more are in the process of evolving a suitable strategy. Most of the quality assurance bodies were established in the nineties and after a few years of practical experience, they are rethinking many issues of quality assurance. At this juncture where countries look for experiences and practices elsewhere, the experience of India has many valuable lessons and this report is an attempt to share those developments..

Technological Constraints

Emerging 3D-related technologies such as augmented reality, virtual reality, mixed reality, and stereoscopy have gained remarkable growth due to their numerous applications in the entertainment, gaming, and electromedical industries. In particular, the 3D television (3DTV) and free-viewpoint television (FTV) enhance viewers’ television experience by providing immersion. They need an infinite number of views to provide a full parallax to the viewer, which is not practical due to various financial and technological constraints. Therefore, novel 3D views are generated from a set of available views and their depth maps using depth-image-based rendering (DIBR) techniques. The quality of a DIBR-synthesized image may be compromised for several reasons, e.g., inaccurate depth estimation. Since depth is important in this application, inaccuracies in depth maps lead to different textural and structural distortions that degrade the quality of the generated image and result in a poor quality of experience (QoE). Therefore, quality assessment DIBR-generated images are essential to guarantee an appreciative QoE. This paper aims at estimating the quality of DIBR-synthesized images and proposes a novel 3D objective image quality metric. The proposed algorithm aims to measure both textural and structural distortions in the DIBR image by exploiting the contrast sensitivity and the Hausdorff distance, respectively. The two measures are combined to estimate an overall quality score. The experimental evaluations performed on the benchmark MCL-3D dataset show that the proposed metric is reliable and accurate, and performs better than existing 2D and 3D quality assessment metrics.
