Structure From Motion focus stacking Cultural Heritage small artefacts photogrammetry
2016/11/11
Digital documentation and high-quality 3D representation are always more requested in many disciplines and areas due to the large amount of technologies and data available for fast, detailed and quick...
Popper's Contribution to the Philosophical Study of Artifacts
technical artifacts three worlds embodied World 3 objects (partial)autonomy non-neutrality
2016/5/30
This paper aims to critically discuss the versatility of Popper’s theory of three worlds in the analysis of issues related to the ontological status and character of technical artifacts. Despite being...

2015/11/9
With growing interest in the role of teachers as the key mediators between educational policies and outcomes, the importance of developing good measures of classroom processes has become increasingly ...
Perceptual artifacts and phenomena:Gibson's role in the 20th century
Perceptual artifacts phenomena Gibson century
2015/8/13
The concepts of invariants and cues are useful, as are those of dorsal and ventral streams, but Norman overgeneralizes when interweav-ing them. Cues are not confined to identification tasks, invariant...
sEMG during Whole-Body Vibration Contains Motion Artifacts and Reflex Activity
Stretch reflex vibration training power spectral density frequency analysis filtering spectral linear interpolation
2015/5/26
The purpose of this study was to determine whether the excessive spikes observed in the surface electromyography (sEMG) spectrum recorded during whole-body vibration (WBV) exercises contain motion art...

3D modelling data processing waterlogged artefacts restoration laser scanning image-based modelling photogrammetry
2015/4/23
The fragility of organic artefacts in presence of water and their volumetric variation caused by the marine life on or surrounding them dictate that their physical dimensions be measured soon after th...
INVESTIGATING 3D RECONSTRUCTION METHODS FOR SMALL ARTIFACTS
Laser Scanning SfM 3Dmodels Artifacts
2015/3/3
Small artifacts have always been a real challenge when it comes to 3D modelling. They usually present severe difficulties for their 3D reconstruction. Lately, the demand for the production of 3D model...
3D Measurement System Using Line Laser for Archeological Artifacts
Digital Archeology Laser-beam Jomon-pottery 3D-measurement
2015/1/6
We developed ortho-projection and drawing system for reduction of record work of archeological artifacts. But, in this system, there are lacks of data. They were caused by position of source-light (ph...
