3D objects descriptors methods: Overview and trends
2017
International audience; Object recognition or object's category recognition under varying conditions is one of the most astonishing capabilities of human visual system. The scientists in computer vision have been trying for decades to reproduce this ability by implementing algorithms and providing computers with appropriate tools. Hence, several intelligent systems have been proposed. To act in this field, numerous approaches have been proposed. In this paper we present an overview of the current trend in 3D objects recognition and describe some representative state of the art methods, highlighting their limits and complexity.
A new weighted normal-based filter for 3D mesh denoising
2018
In this paper, we propose a normal based filtering method for 3D mesh denoising. For this purpose, we compute the new triangle normal vectors by using a weighted sum of the average (smoothness) and the myriad (sharpness) filters in each neighborhood. These weights, that reflect the degree of the surface sharpness, are calculated according to the statistical distribution of the angles between the normal vectors of the triangles. The histogram of the angles between surface normal vectors is accurately fitted by the well known Cauchy distribution. Here, we justify the use of the myriad filter whose estimated value represents the optimum of the location parameter of the investigated distributio…
Creating Digital Musical Instruments With and for Children: Including Vocal Sketching as a Method for Engaging in Codesign
2020
International audience; A class of master of science students and a group of preschool children codesigned new digital musical instruments based on workshop interviews involving vocal sketching, a method for imitating and portraying sounds. The aim of the study was to explore how the students and children would approach vocal sketching as one of several design methods. The children described musical instruments to the students using vocal sketching and other modalities (verbal, drawing, gestures). The resulting instruments built by the students were showcased at the Swedish Museum of Performing Arts in Stockholm. Although all the children tried vocal sketching during preparatory tasks, few …
Towards Understanding of Software Engineer Motivation in Globally Distributed Projects
2011
Motivation in software engineering is reported to be a source for performance improvement, which leads to project overall success. Since it is a soft factor and difficult to quantify it is usually neglected. Research in this field is rather scarce and outdated. On the basis of a recent systematic review of software engineers' motivation we set an agenda for further investigation of the role of motivation in contemporary projects. As software organizations nowadays seek opportunities inherited in both - global software development (GSD) and agile projects, it is important to understand how different project environments influence motivation.

Best Practices for International eSourcing of Software Products and Services
2008
This paper analyzes how the information and communications technology-supported international eSourcing of software products and services (IeS) can be effectively executed. The extant literature falls short of providing a systematic and detailed enough set of best practices to guide IeS. This paper presents best practices for IeS to facilitate further research, and to help managers and other stakeholders to understand, execute, and proactively improve and manage international eSourcing. The practices emphasize the need to establish and enact rigorous, mature, and quantitatively managed eSourcing life- cycles in order to transcend temporal, geographical, social, technical, and other boundari…
Analysing software integration scenarios: the case of telecommunications operations software
2008
Telecom operators deploy a vast number of software systems to support their operations. Vendors of this software often integrate in their products several software systems, in order to enable innovations, minimize customer's integration efforts, etc. Different integration scenarios can be envisioned, and the issue of identifying more beneficial scenarios is of a great importance to the vendors. This paper aims at analyzing different software integration scenarios from the viewpoint of their support for innovations, and focuses on the context of telecommunications operations software. For each scenario, the overall modularity of the set of software systems is evaluated, and the expected bene…
Apathy Towards the Integration of Usability Work: A Case of System Justification
2016
In this article we report from a case study of a software development organization and we study in particular the developers’ and product managers’ attitudes towards integrating usability work into software development. We offer explanations based on system justification theory illuminating what would-be integrators might be up against. The analysis shows how the developers only pay lip service to usability work and how they treat users superficially. It further shows how that leads to stereotyping of usability designers and users in order to preserve status quo, and how internalization of inequality between the developers and usability designers rationalizes the preservation of status quo.…
Explaining Change Paths of Systems and Software Development Practices
2010
This chapter discusses how systems development practices are shaped. Based on interviews conducted in ten development organizations and previous literature, we identify eight types of change paths in systems development practices: emergence, adoption, idealization, formalization, abandonment, informalization, entropy, and disobedience. We argue that the eight change path types provide an integrated theoretical framework on the study of how systems development practices change in organizations, projects, and among individual developers in a given context. We discuss how this framework complements existing theories and concepts of the contemporary literature on systems development.
MetaEdit+ A Fully Configurable Multi-User and Multi-Tool CASE and CAME Environment
1996
Computer Aided Software Engineering (CASE) environments have spread at a lower pace than expected. One reason for this is the immaturity of existing environments in supporting development in-the-large and by-many and their inability to address the varying needs of the software developers. In this paper we report on the development of a next generation CASE environment called MetaEdit+. The environment seeks to overcome all the above deficiencies, but in particular pays attention to catering for the varying needs of the software developers. MetaEdit+ is a multi-method, multi-tool platform for both CASE and Computer Aided Method Engineering (CAME). As a CASE tool it establishes a versatile an…
