A robot manipulating objects while, say, working in a kitchen, will benefit from understanding which items are composed of the same materials. With this knowledge, the robot would know to exert a simi...
CONTENT PRESERVING WATERMARKING FOR MEDICAL IMAGES USING SHEARLET TRANSFORM AND SVD
Watermarking Medical images Shearlet transform SVD
2017/5/15
Medical Image Watermarking (MIW) is a special field of a watermarking due to the requirements of the Digital Imaging and COmmunications in Medicine (DICOM) standard since 1993. All 20 parts of the DIC...
New theoretical interpretation of images of double out-of-Galactic radiosources
New theoretical interpretation images double out-of-Galactic radiosources
2016/5/20
The author of the paper presents a quite new theoretical model of a double radiosource designed on the basis of the data of radiotelescopic observations and the new conception of the physics of active...
Likelihood-based classification of high resolution images to generate the initial topology and geometry of land cover segments
Likelihood-based classification Maximum likelihood classification Geo-information systems
2016/5/20
This paper’s origin is to reach for a way for automatic initiation of shape hypothesis for Model Based Image Analysis (MBIA) in the specific case of agricultural fields. A solution is to start with lo...
Integration of High Resolution Quicbird Images to GoogleEarth
Image Processing Information Content Image Understanding

As known, at the present time, remote sensing technologies are being improved and year by year, by launching new satellites whose image taking configurations are improved with new techniques, images c...
On-orbit Stellar Camera Calibration based on Space Resection with Multi-images
on-orbit calibration stellar camera space resection multi star images satellite attitude accuracy
2015/11/20
Due to the intense vibration and/or the change of space environmental factors such as temperature, pressure, etc., the stellar camera parameters might change during satellites launching or while orbit...
THE APPLICATION OF CONTENT-BASED INDEXING AND RETRIEVAL OF DIGITAL PICTURES AND RANGE IMAGES TO THE 3D VIRTUAL RECONSTRUCTION OF COMPLEX SITES AND ARCHITECTURES
Content-based indexing/retrieval model range images registration three-dimensional 3D
2015/10/8
The modelling of complex objects and sites involve the acquisition of a large number of texture maps and range images; each one of
them representing a particular viewing angle. These views must be c...
Hopfield Networks in Relevance and Redundancy Feature Selection Applied to Classification of Biomedical High-Resolution Micro-CT Images
feature selection image features pattern classification
2015/7/28
We study filter–based feature selection methods for classification of biomedical images. For feature selection, we use two filters — a relevance filter which measures usefulness of individual features...
Monoscale Ridgelets for the Representation of Images with Edges
Edges Partitioning Local Fourier Transform (JPEG) Ridge functions Ridgelets Radon transform Nonlinear approximation
2015/6/17
In a previous paper [1], the author introduced a new system for representing multivariate functions, namely, the ridgelets. In a following article [3], ridgelets were shown to be optimal for represent...

2015/6/17
This paper reviews the development of several recent tools from computational harmonic analysis. These new systems are presented under a coherent perspective, namely, the representation of bivariate f...
EXTRACTING 3D FREE-FORM SURFACE BOUNDARIES OF MAN-MADE OBJECTS FROM MULTIPLE CALIBRATED IMAGES: A ROBUST, ACCURATE AND HIGH RESOLVING POWER EDGEL MATCHING AND CHAINING APPROACH
Photogrammetry 3D Reconstruction
2015/5/18
This paper describes a purely geometrical approach for matching and chaining edgels, i.e. contours points with their tangent direction,
to reconstruct in a general way 3D rectilinear or curved surfac...
GEOMETRIC ASPECTS OF THE HANDLING OF SPACE IMAGES

2015/5/12
Only few space images do have a perspective geometry like aerial cameras. But also the Russian perspective photos do have not
negligible systematic image errors. By this reason special mathematical m...
