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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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...
