PHOTOGRAMMETRIC TECHNIQUES FOR PALEOANTHROPOLOGICAL OBJECTS PRESERVING AND STUDYING
Fossil Accuracy Automation 3D model Palaeoanthropology Non-contact measurements
2018/6/4
Paleo-anthropological research has its specificity closely related with studied objects. Their complicated shape arises from anatomical features of human skull and other skeletal bones. The degree of ...
Vectorization, Edge Preserving Smoothing and Dimensioning of Profiles in Laser Scanner Point Clouds
Laser scanning Edge preserving smoothing Profile
2015/12/16
The 3D geometry of an object can be captured very efficiently using a terrestrial laser scanner. By modelling and visualisation of
these 3D data, it is possible to obtain vectorized geometric informa...
Preserving Ground Plan and Facade Lines for 3D Building Generalization
3D GIS 3D City Models Visualization Buildings Generalization Adjustment
2015/12/2
As 3D city models are becoming available and attractive for consumer purposes in personal navigation systems or visualization applications, the hardware used to visualize these models changes from spe...
EDGE-PRESERVING SMOOTHING OF HIGH-RESOLUTION IMAGES WITH A PARTIAL MULTIFRACTAL RECONSTRUCTION SCHEME
Remote Sensing, Segmentation High-Resolution
2015/6/1
We introduce a novel approach as a preprocessing step for
feature extraction and/or image segmentation. The method is derived from the multifractal formalism proposed for image
compression. This pro...
MULTI-QUADRATIC DYNAMIC PROGRAMMING PROCEDURE OF EDGE– PRESERVING DENOISING FOR MEDICAL IMAGES
Dynamic programming Bayesian framework
2015/5/21
In this paper, we present a computationally efficient technique for edge preserving in medical image smoothing,
which is developed on the basis of dynamic programming multi-quadratic procedure. Addi...
A NEW APPROACH TO EDGE-PRESERVING SMOOTHING FOR EDGE EXTRACTION AND IMAGE SEGMENTATION
Image Processing Filtering Radiometric Quality Feature Extraction Edge Extraction Segmentation Multi-spectral Data
2014/12/31
This paper introduces a new approach to edge-preserving smoothing of digital images. It is designed for an effective elimination of the image noise within digital images what is an essential step in a...
DIMENSIONALITY REDUCTION OF HYPERSPECTRAL IMAGES BY COMBINATION OF NON-PARAMETRIC WEIGHTED FEATURE EXTRACTION (NWFE) AND MODIFIED NEIGHBORHOOD PRESERVING EMBEDDING (NPE)
Hyperspectral Imagery Feature Extraction LDA NPE Classification
2014/12/1
This paper combine two conventional feature extraction methods (NWFE&NPE) in a novel framework and present a new semi-supervised feature extraction method called Adjusted Semi supervised Discriminant ...
Scalable and Detail-Preserving Ground Surface Reconstruction from Large 3D Point Clouds Acquired by Mobile Mapping Systems
Surface reconstruction LiDAR geometry urban mobile mapping
2014/9/9
The currently existing mobile mapping systems equipped with active 3D sensors allow to acquire the environment with high sampling rates at high vehicle velocities. While providing an effective solutio...
QUALITY ASSESSMENT IN RIVER NETWORK GENERALISATION BY PRESERVING THE DRAINAGE PATTERN
river network generalisation quality assessment drainage pattern fuzzy logic
2014/4/24
The drainage pattern of a river network is the arrangement in which a stream erodes the channels of its network of tributaries. It can
reflect the geographical characteristics of a river network to ...
