Single image dehazing is a challenging task, for which the domain shift between synthetic training data and real-world testing images usually leads to degradation of existing methods. To address this issue, we propose novel framework collaborating with unlabeled real data. First, develop disentangled network (DID-Net), disentangles feature representations into three component maps, i.e. latent haze-free image, transmission map, global atmospheric light estimate, respecting physical model...

The increasing number of presentation attacks on reliable face matching has raised concerns and garnered attention towards anti-spoofing (FAS). However, existing methods for FAS modeling commonly fuse multiple visual modalities (e.g., RGB, Depth, Infrared) in a straightforward manner, disregarding latent feature gaps that can hinder representation learning. To address this challenge, we propose novel multimodal framework (mmFAS) focuses explicit alignment fusion features across different...

Long waves are amplified as short-wave groups shoal and break over reefs, therefore, having significant impacts on coastal inundation, structure stability, sediment transport. This study investigated the cross-reef variation of long-wave energy exchange with group a reef using fully nonlinear analysis simulation results by non-hydrostatic model SWASH. The objective was to elucidate mechanisms transformation under forcing reef, assess consequences simplifications in linear weakly analyses...

Abstract The present paper aims to clarify the mechanism of infragravity wave (IGW) energy amplification over nearshore shoals reported in recent studies. Wave transformation and transfer between short waves (SWs) IGWs were investigated using SWASH model for nonbreaking random propagating trapezoid with different bottom slopes. It was found that time lag relative SW groups is major from SWs IGW all segments shoal. generated on front slope enlarged plateau shoal, decreases rear higher...

In the present study, analytical solutions of IG at O ( β 1 ) = h x /(Δ kh ), bottom slope, Δ k group wavenumber, depth) intermediate and are derived separately. case off-resonance [ μ −1 where resonant departure parameter, c g speed] water, additional quadrature with wave forcing (hereinafter, nonequilibrium response or component) induced relative to...

Video dehazing using deep-learning based methods has just received increasing attention in recent years. However, most existing tackle temporal consistency the color domain only, which are less sensitive to small and imperceptible motions a video, due fog's drift diffusion. In this work, we investigate frequency domain, enables us capture effectively, find that phase component contains more semantic structures yet haze information than amplitude of hazy image. Based on these observations,...

Fast and accurate estimation of wave runup is needed for coral-reef islands, but most the existing formulae are not applicable in this context. Tree-based models were applied to comprehensive numerical database Pearson et al. (J. Geophys. Res.

It found that, conditions, reef roughness, reef-flat length generally crucial predicting runup, while importance...

A new definition of wave groupiness factor is proposed here based on wave-height history trains. This takes into account the dual roles both zero-downcrossing height and period in spatial temporal evolution groupiness. It demonstrated that less sensitive to operational can describe degree not only linear trains but also highly nonlinear ones. The variation across a laboratory fringing reef was investigated. Results showed shoaling zone, became more pronounced. Decreasing triggered by...

An artificial neural network (ANN) tool trained using a backpropagation algorithm was developed to predict the overtopping rate of impermeable vertical seawalls on coral reefs. The training database produced from simulations nonhydrostatic wave model calibrated subset experimental data and covered wide range hydrological conditions, reef morphologies, seawall heights. ANN configuration optimized through sensitivity analysis overfitting prevented k-fold cross-validation technique....
