HDR image watermarking using saliency detection and quantization index modulation

no code implementations22 Feb 2023 Ahmed Khan, Minoru Kuribayashi, KokSheik Wong, Vishnu Monn Baskaran

First, the host image goes through our proposed salient object detection model to produce a saliency map, which is, in turn, exploited to segment the foreground and background of the host image.

A Generalized Approach for Cancellable Template and Its Realization for Minutia Cylinder-Code

no code implementations2 Mar 2022 Xingbo Dong, Zhe Jin, KokSheik Wong

In this paper, we proposed a generalized version of IoM hashing namely gIoM, and therefore the unordered and variable size biometric template can be used.

Synthesize-It-Classifier: Learning a Generative Classifier Through Recurrent Self-Analysis

no code implementations CVPR 2021 Arghya Pal, Raphael C.-W. Phan, KokSheik Wong

During training, the classifier iteratively uses these synthesized images as fake samples and re-estimates the class boundary in a recurrent fashion to improve both the classification accuracy and quality of synthetic images.

Synthesize-It-Classifier: Learning a Generative Classifier through RecurrentSelf-analysis

no code implementations26 Mar 2021 Arghya Pal, Rapha Phan, KokSheik Wong

During training, the classifier iteratively uses these synthesized images as fake samples and re-estimates the class boundary in a recurrent fashion to improve both the classification accuracy and quality of synthetic images.

On the Risk of Cancelable Biometrics

no code implementations17 Oct 2019 Xingbo Dong, Jaewoo Park, Zhe Jin, Andrew Beng Jin Teoh, Massimo Tistarelli, KokSheik Wong

Cancelable biometrics (CB) employs an irreversible transformation to convert the biometric features into transformed templates while preserving the relative distance between two templates for security and privacy protection.

Spontaneous Subtle Expression Detection and Recognition based on Facial Strain

no code implementations9 Jun 2016 Sze-Teng Liong, John See, Raphael Chung-Wei Phan, Yee-Hui Oh, Anh Cat Le Ngo, KokSheik Wong, Su-Wei Tan

In this paper, we present a novel method for detecting and recognizing micro-expressions by utilizing facial optical strain magnitudes to construct optical strain features and optical strain weighted features.

Less is More: Micro-expression Recognition from Video using Apex Frame

no code implementations6 Jun 2016 Sze-Teng Liong, John See, KokSheik Wong, Raphael C. -W. Phan

The apex frame of a video contains the highest intensity of expression changes among all frames, while the onset is the perfect choice of a reference frame with neutral expression.
