Bimetallic nanoalloys with a wide variety of
structures and compositions have been fabricated through many diverse techniques. Generally, various steps and chemicals are involved in their fabrication. In this study, the ...
Three-Dimensional Integral Imaging for Gesture Recognition Under Occlusions
(Institute of Electrical and Electronics Engineers (IEEE), 2017-02)
Over the last years, three-dimensional (3-D) imaging has been applied to human action and gesture recognition, usually in the form of depth maps from RGB-D sensors. An alternative which has not been explored is 3-D integral ...
Prior-based probabilistic latent semantic analysis for multimedia retrieval
(Springer Verlag, 2017)
Topic models have shown to be one of the most effective tools in Content-Based
Multimedia Retrieval (CBMR). However, the high computational learning cost together
with the huge expansion of multimedia collections limit ...
Sparse Multi-modal probabilistic Latent Semantic Analysis for Single-Image Super-Resolution
(Elsevier, 2018)
This paper presents a novel single-image super-resolution (SR) approach
based on latent topics in order to take advantage of the semantics pervading
the topic space when super-resolving images. Image semantics has shown ...
Unsupervised Remote Sensing Image Retrieval Using Probabilistic Latent Semantic Hashing
(Institute of Electrical and Electronics Engineers, 2020-02-06)
Unsupervised hashing methods have attracted considerable attention in large-scale remote sensing (RS) image retrieval, due to their capability for massive data processing with significantly reduced storage and computation. ...
Sentinel-3/FLEX Biophysical Product Confidence Using Sentinel-2 Land-Cover Spatial Distributions
(IEEE, 2021-03-11)
The estimation of biophysical variables from remote sensing data raises important challenges in terms of the acquisition technology and its limitations. In this way, some vegetation parameters, such as chlorophyll fluorescence, ...
Multimodal Probabilistic Latent Semantic Analysis for Sentinel-1 and Sentinel-2 Image Fusion
(IEEE, 2018-09)
Probabilistic topic models have recently shown a great potential in the remote sensing image fusion field, which is particularly helpful in land-cover categorization tasks. This letter first studies the application of ...
DAT-CNN: Dual Attention Temporal CNN for Time-Resolving Sentinel-3 Vegetation Indices
(IEEE, 2022-03-22)
The synergies between Sentinel-3 (S3) and the forthcoming fluorescence explorer (FLEX) mission bring us the opportunity of using S3 vegetation indices (VI) as proxies of the
solar-induced chlorophyll fluorescence (SIF) ...
Recommendation-Based Conceptual Modeling and Ontology Evolution Framework (CMOE+)
(Springer Verlag, 2017-08)
Within an enterprise, various stakeholders create different conceptual models, such as process, data, and requirements models. These models are fundamentally based on similar underlying enterprise (domain) concepts, but ...
