High-Sensitivity High-Speed Compressive Spectrometer for Raman Imaging
(American Chemical Society, 2019-04-25)
Compressive Raman is a recent framework that allows for large data compression of microspectroscopy during its measurement. Because of its inherent multiplexing architecture, it has shown imaging speeds considerably higher ...
Depth estimation improvement in 3D integral imaging using an edge removal approach
(Springer, 2018)
A new depth estimation method for 3D reconstruction in a synthetic aperture integral imaging framework is presented. This
method removes the edges of the objects in the elemental images when the objects are in focus. This ...
Partially-coherent spirally-polarized gradual-edge imaging
(Elsevier, 2019)
In this work we develop a partially-coherent spirally-polarized imaging system for generating gradual edge detection images. A rotating diffuser is used for producing illumination sources with tunable degree of coherence.
Using ...
Remote Sensing Image Fusion Using Hierarchical Multimodal Probabilistic Latent Semantic Analysis
(IEEE, 2018-11)
The generative semantic nature of probabilistic topic models has recently shown encouraging results within the remote sensing image fusion field when conducting land cover categorization. However, standard topic models ...
Modelling contextual constraints in probabilistic relaxation for multi-class semi-supervised learning
(Elsevier, 2014)
This paper proposes a semi-supervised approach based on probabilistic relaxation theory. The algorithm performs a consistent multi-class assignment of labels according to the contextual information constraints. We start ...
Reducing complexity in polygonal meshes with view-based saliency
(Elsevier, 2014-08)
Salient features in 3D meshes such as small high-curvature details in the middle of largely flat regions are easily ignored by most mesh simplification methods. Nevertheless, these features can be perceived by human observers ...
A bias correction function for classification performance assessment in two-class imbalanced problems
(Elsevier, 2014)
This paper introduces a framework that allows to mitigate the impact of class imbalance on most scalar performance measures when used to evaluate the behavior of classifiers. Formally, a correction function is defined with ...
Human gesture recognition using three-dimensional integral imaging
(Optical Society of America, 2014)
Three-dimensional (3D) integral imaging allows one to reconstruct a 3D scene, including range information, and provides sectional refocused imaging of 3D objects at different ranges. This paper explores the potential use ...
Simplification method for textured polygonal meshes based on structural appearance
(Springer-Verlag, 2013-05)
This paper proposes an image-based simplification method for textured triangle meshes that preserves the structural appearance of textured models. Models used in interactive applications are usually composed of textured ...
Smooth shadow boundaries with exponentially-warped gaussian filtering
(Elsevier, 2013-05)
Shadow mapping is widely used in computer graphics for efficiently rendering shadows in real-time applications. Shadow maps cannot be filtered as regular textures, thus their limited resolution can cause severe shadow map ...
