A better similarity mapping function across heterogeneous high-dimensional features is very desirable for many applications involving multi-modal data. In this paper, we introduce coupled dictionary learning (DL) into supervised sparse coding for multi-modal (crossmedia) retrieval. We call this Supervised coupleddictionary learning with group structures for MultiModal retrieval (SliM). SliM for...

Simulation is the most viable solution for the functional verification of SoC. The acceleration of simulation with multi-FPGA is a promising method to comply with the increasing complexity and large gate capacity of SoC. The most time-consuming factor of multi-FPGA simulation accelerator is signal transfer time between simulator and multi-FPGA system. This paper proposes a performance driven de...

This study aimed at introducing short-T1/T2 compartment to MR fingerprinting (MRF) 3 T. Water that is bound myelin macromolecules have significantly shorter T1 and T2 than free water can be distinguished from by multi-compartment analysis. We developed a new multi-inversion-recovery (mIR) mapping-MRF based on an unbalanced steady-state coherent sequence (FISP). mIR pulses with interval of 400 o...

Reedbeds across the UK are amongst the most important habitats for rare and endangered birds, wildlife and organisms. However, over the past century, this valued wetland habitat has experienced a drastic reduction in quality and spatial coverage due to pressures from human related activities. To this end, conservation organisations across the UK have been charged with the task of conserving and...

Identification and mapping of the significant alterations are the main objectives of the exploration geochemical surveys. The field study is time-consuming and costly to produce the classified maps. Therefore, the processing of remotely sensed data, which provide timely and multi-band (multi-layer) data, can be substituted for the field study. In this study, the ASTER imagery is used for altera...

We use an inverse scattering approach to study multi-peakon solutions of the Degasperis–Procesi (DP) equation, an integrable PDE similar to the Camassa–Holm shallow water equation. The spectral problem associated to the DP equation is equivalent under a change of variables to what we call the cubic string problem, which is a third order non-selfadjoint generalization of the well-known equation ...

Sub-pixel mapping technique can specify the location of each class within the pixels based on the assumption of spatial dependence. Traditional sub-pixel mapping algorithms only consider the spatial dependence at the pixel level. The spatial dependence of each sub-pixel is ignored and sub-pixel spatial relation is lost. In this paper, a novel multi-objective sub-pixel mapping framework based on...

Fine-tuning of multi-color emission characteristics of upconversion lanthanide-ion-doped nanocrystals is of high importance for 3-D color displays, multi-color bio-imaging, and multiplexed cellular labeling. Here, we report a strategy enabling crystal phase transition and morphology transformation between GdF3:Yb ,Tm and GdOF:Yb,Tm nanocrystals for fine-tuning of upconversion multi-color emissi...
