Loss less data hiding can extract the embedded secret data and restore the cover media to its original status. Wang et al. in 2010 proposed a loss less data hiding method to embed secret message on VQ indices but their scheme has the encoded bit stream over-expanded. This paper improves their embedding approach by employing the index clusters with localization to enhance the similarity of adjacent...
Framework-based1 applications are quite popularly used in current commercial applications. Framework-based applications are often controlled by XML configuration files. However, most of these frameworks are complex or not well documented, which poses a great challenge for programmers to correctly utilize them. To overcome these difficulties, we propose a new method to recommend XML configuration snippets...
Distributed video coding (DVC) is an emerging application of distributed source coding (DSC). Since coding complexity is shifted from encoder sides to decoder sides, DVC is appropriate and useful for the environments where low power encoding is allowed. The coding performance of DVC is greatly affected by side information extracted from bi-directional key frames which is enhanced through channel decoding...
In the past, the concept of performing the task of feature selection by attribute clustering was proposed. Hong et al. thus proposed several genetic algorithms for finding appropriate attribute clusters. In this paper, we attempt to improve the performance of the GA-based attribute-clustering process based on the grouping genetic algorithm (GGA). In our approach, the general GGA representation and...
This paper proposes a new approach to reduce the effort of building formal models representative of the structure and behaviour of Graphical User Interfaces (GUI). The main goal is to automatically extract the GUI model with a dynamic reverse engineering process, consisting in an exploration phase, that extracts information by interacting with the GUI, and in a model generation phase that, making...
Encoding data independently in cyan, magenta, and yellow (CMY) print colorant channels with detection in complementary Red, green, and blue (RGB) image capture channels offers an attractive framework for extending monochrome barcodes to color with increased data rates. The undesired absorption of colorants in regions of spectral sensitivity of the noncomplementary capture channels, however, gives...
The depth information plays an essential role in the virtual-view (or free-viewpoint) 3D video systems. In this paper, we propose a new algorithm to code a depth map for the purpose of virtual view synthesis. The idea is to use H.264/AVC to represent the rough shape (including depth values) of a depth map and then additional information is transmitted to improve the depth values around the object...
Studying collaboration and its support by IT in experiments has been limited to collecting and analyzing collaboration products and performance criteria ex post. This paper presents CoPrA, a Collaboration Process Analysis technique, which allows investigating behavior of individuals in distributed groups mediated by collaboration technology from a process-oriented perspective. Based on coded communication...
Differential energy watermarking considers the properties that adjacent image blocks have similar energy in the transform domain and it is not sensitive for human system to the characteristics of high frequency, by adjusting the transform domain coefficients to achieve the purpose of watermark. This paper presents a differential energy watermarking method based on macro-block prediction. This method...
Genetic Algorithm and Association Rules both are commonly used methods in data mining. In this paper, a brief overview of Genetic Algorithm and Association Rules has been given, and this paper has presented an improved extract method of association rules of genetic algorithm based on their respective advantages and disadvantages. It also did some research on designing encoding methods, structuring...
Thematic analysis is an approach that is often used for identifying, analyzing, and reporting patterns (themes) within data in primary qualitative research. 'Thematic synthesis' draws on the principles of thematic analysis and identifies the recurring themes or issues from multiple studies, interprets and explains these themes, and draws conclusions in systematic reviews. This paper conceptualizes...
Open Source software is competing successfully in many areas. The commercial sector is recognizing the benefits offered by Open Source development methods that lead to high quality software. Can these benefits be realized in specialized domains where expertise is rare? This study examined discussion forums of an Open Source project in a particular specialized application domain -- electronic medical...
All patient-related medical information during a hospital stay in France, has to be collected and coded in the compilation of medical units discharge documents, according to a standardized approach. The process of describing a patient disease in terms of appropriate diagnostic codes is nevertheless, a non-intuitive operation for the physician. As a consequence, coding errors, inaccuracies and missing...
We propose an XML C source code representation to support developing CASE tools. Since source code is a main artifact of software development, most CASE tools have some features related to source code editor, static analyzer, profiler, etc. To develop such tools, detailed information related to source code is needed. However, it is quite difficult to reuse program analysis features because they do...
This paper proposes a new Audio-Video Synchronization Coding algorithm on the latest H.264/AVC video coding standard. The audio information is only embedded into the last non-zero and non-trailing coefficient during the CAVLC (Context Adaptive Variable Length Coding) process and can be extracted from the video stream at the receiver terminal without distortion. This method is efficient with low computational...
Most healthcare institutions such as hospitals and clinics store their data in the form of databases of various formats. The Health Ontology System that we have developed provides a means to integrate these data with concepts and semantics in the form of a shared cumulative ontology for enabling machines to interpret them. This involves three major software tools, namely, Ontology Generator, Ontology...
To reduce the redundant information in software static analysis and improve the accuracy and efficiency of the information extraction, this paper proposed a syntax trees model based on relational storage mode. Modeling on dependency relationship between terminals will effectively reduce the information redundancy and can be stored in XML (eXtensible Markup Language) format. Using the mature XML parsing...
In this paper we describe a framework of GIS-based system for automated processing of mass remote sensing and geospatial data products as a step in preparation of data for the needs of end users. In particular we employed the GDAL data model and python and GDAL Library to convert HDF5 format data into standard GIS format. We then batch processed all the data to a targeted data type using python coding...
In the storage of the ordered tree, for two weaknesses (the XML document is large and the space-efficient LOUDS bit-string can only describe static trees), the space-efficient-tree package format based on the LOUDS bit-string is proposed. This package format can not only store ordered trees space-efficiently, but also achieve the dynamic operations of ordered trees. In the end, a variety of common...
When the new generation video encoding standard H.264/AVC achieved higher compression ratio and transmission robustness, computational complexity was increased acutely, and was unfavorable in real-time environmental application. Combined the visual perception characteristics and video encoding information, a new extraction method for motion region of interest and optimized coding scheme were proposed...
