A Reversible Data Hiding Scheme for 3D Polygonal Models Based on Histogram Shifting with High Embedding Capacity
3D Research - Tập 6 - Trang 1-12 - 2015
Reversibility is the ability to recover the stego media back to the cover media
without any error after correctly extracting the secret message. This study
proposes a reversible data hiding scheme for 3D polygonal models based on
histogram shifting. Specifically, the histogram construction is based on the
geometric similarity between neighboring vertices. The distances between the
neighboring vert...
Efficient view based 3-D object retrieval using Hidden Markov Model
3D Research - Tập 4 - Trang 1-7 - 2013
Recent research effort has been dedicated to view based 3-D object retrieval,
because of highly discriminative property of 3-D object and has multi view
representation. The state-of-art method is highly depending on their own camera
array setting for capturing views of 3-D object and use complex Zernike
descriptor, HAC for representative view selection which limit their practical
application and m...
Metaheuristic Techniques for Detection of Optic Disc in Retinal Fundus Images
3D Research - Tập 9 - Trang 1-22 - 2018
Eye diseases like glaucoma and diabetic retinopathy are known to be the thieves
of eye-sight that are responsible for causing the vision loss worldwide.
Automatic detection of such diseases with the help of the digital color fundus
photography helps in early diagnosis and treatment. From the fundus images,
optic disc is required to be analyzed to diagnose the disease. In this paper, a
technique ha...
Modeling and Optimization of Tool Wear and Surface Roughness in Turning of Al/SiCp Using Response Surface Methodology
3D Research - Tập 9 - Trang 1-13 - 2018
Nowadays metal matrix composites are widely utilized in major industries such as
aerospace and automotive because of their excellent properties in association
with non-reinforced. This research work is attempted to analyze the consequence
of cutting parameters on tool life and surface quality. The experimental work is
consist of turning Al/SiCp (45%SiCp) weight with uncoated Carbide tools and the
...
Introducing a Public Stereoscopic 3D High Dynamic Range (SHDR) Video Database
3D Research - Tập 8 - Trang 1-9 - 2017
High dynamic range (HDR) displays and cameras are paving their ways through the
consumer market at a rapid growth rate. Thanks to TV and camera manufacturers,
HDR systems are now becoming available commercially to end users. This is taking
place only a few years after the blooming of 3D video technologies. MPEG/ITU are
also actively working towards the standardization of these technologies.
Howeve...
Multi-sensor 3D volumetric reconstruction using CUDA
3D Research - Tập 2 - Trang 1-14 - 2011
This paper presents a full-body volumetric reconstruction of a person in a scene
using a sensor network, where some of them can be mobile. The sensor network is
comprised of couples of camera and inertial sensor (IS). Taking advantage of IS,
the 3D reconstruction is performed using no planar ground assumption. Moreover,
IS in each couple is used to define a virtual camera whose image plane is
hori...
Globally optimal rotation alignment of spherical surfaces with associated scalar values
3D Research - Tập 4 - Trang 1-7 - 2013
We propose a new approach to global optimization algorithm based on controlled
random search techniques for rotational alignment of spherical surfaces with
associated scalar values. To reduce the distortion in correspondence and
increase efficiency, the spherical surface is first re-sampled using a geodesic
sphere. The rotation in space is represented using the modified Rodrigues
parameters. Corre...
Contrast Enhancement Technique Based on Lifting Wavelet Transform
3D Research - Tập 9 - Trang 1-13 - 2018
Contrast enhancement is an indispensable process for improving the subjective
quality and information content of an image. Adjustment in the relative
brightness and darkness of an image is done in order to attain the same. This
paper employs lifting wavelet transform (LWT) to enhance the image since it is
computationally inexpensive. The application of LWT results in the low and high
frequency com...
LGSA: Hybrid Task Scheduling in Multi Objective Functionality in Cloud Computing Environment
3D Research - Tập 10 - Trang 1-16 - 2019
Cloud computing turns to be a big shift from the conventional perception of the
IT resources. It is a transpiring computing technology that is increasingly
stabling itself as the promising future of distributed on-demand computing. The
processes comprised in it are the ones that act as a vital backbone and which
strengthen the entire stream of cloud computing as a whole. In specific, Task
scheduli...
Enhancing Security of Double Random Phase Encoding Based on Random S-Box
3D Research - Tập 9 - Trang 1-20 - 2018
In this paper, we propose a novel asymmetric cryptosystem for double random
phase encoding (DRPE) using random S-Box. While utilising S-Box separately is
not reliable and DRPE does not support non-linearity, so, our system unites the
effectiveness of S-Box with an asymmetric system of DRPE (through Fourier
transform). The uniqueness of proposed cryptosystem lies on employing high
sensitivity dynam...
