A Cascade Face Spoofing Detector Based on Face Anti-Spoofing R-CNN and Improved Retinex LBP
IEEE Access, 2019 In consideration of secure and convenient, face gains increasing attention in variety of fields during the past decades. Since human face is most accessible from our daily life and preserves the richest information, face based biometric systems are ...

Gravity optimised particle filter for hand tracking [PDF]
, 2014 This paper presents a gravity optimised particle filter (GOPF) where the magnitude of the gravitational force for every particle is proportional to its weight. GOPF attracts nearby particles and replicates new particles as if moving the particles towards

Paraunitary oversampled filter bank design for channel coding [PDF]
, 2006 Oversampled filter banks (OSFBs) have been considered for channel coding, since their redundancy can be utilised to permit the detection and correction of channel errors.

An Adaptive Two-Scale Image Fusion of Visible and Infrared Images
IEEE Access, 2019 In this paper, we proposed an adaptive two-scale image fusion method using latent low-rank representation (LatLRR). First, both IR and VI images are decomposed into a two-scale representation using LatLRR to generate low-rank parts (the global structure)

On the Design of Oversampled Filter Banks for Channel Coding [PDF]
, 2004 Oversampled filter banks have been considered for channel coding, because they introduce redundancy into the subband representation of signals and permit more freedom in their design than critically sampled structures.

SAR Image De-Noising Based on Shift Invariant K-SVD and Guided Filter
Remote Sensing, 2017 Finding a way to effectively suppress speckle in SAR images has great significance. K-means singular value decomposition (K-SVD) has shown great potential in SAR image de-noising.

Structural Information Reconstruction of Distorted Underwater Images Using Image Registration
Applied Sciences, 2020 Imaging through wavy air-water surface suffers from uneven geometric distortions and motion blur due to surface fluctuations. Structural information of distorted underwater images is needed to correct this in some cases, such as submarine cable ...

Filter design for filtered back-projection guided by the interpolation model [PDF]
SPIE Proceedings, 2002 We consider using spline interpolation to improve the standard filtered back-projection (FBP) tomographic reconstruction algorithm. In particular, we propose to link the design of the filtering operator with the interpolation model that is applied to the sinogram.
