HDR image watermarking using saliency detection and quantization index modulation
Ahmed Khan, Minoru Kuribayashi, KokSheik Wong +1
High-dynamic range (HDR) images are circulated rapidly over the internet with risks of being exploited for unauthorized usage. To protect these images, some HDR image based waterma…
A Generalized Approach for Cancellable Template and Its Realization for Minutia Cylinder-Code
Xingbo Dong, Zhe Jin, KokSheik Wong
Hashing technology gains much attention in protecting the biometric template lately. For instance, Index-of-Max (IoM), a recent reported hashing technique, is a ranking-based local…
Synthesize-It-Classifier: Learning a Generative Classifier through RecurrentSelf-analysis
Arghya Pal, Rapha Phan, KokSheik Wong
In this work, we show the generative capability of an image classifier network by synthesizing high-resolution, photo-realistic, and diverse images at scale. The overall methodolog…
On the Risk of Cancelable Biometrics
Xingbo Dong, Jaewoo Park, Zhe Jin +3
Cancelable biometrics (CB) employs an irreversible transformation to convert the biometric features into transformed templates while preserving the relative distance between two te…
Spontaneous Subtle Expression Detection and Recognition based on Facial Strain
Sze-Teng Liong, John See, Raphael Chung-Wei Phan +4
Optical strain is an extension of optical flow that is capable of quantifying subtle changes on faces and representing the minute facial motion intensities at the pixel level. This…
Less is More: Micro-expression Recognition from Video using Apex Frame
Sze-Teng Liong, John See, KokSheik Wong +1
Despite recent interest and advances in facial micro-expression research, there is still plenty room for improvement in terms of micro-expression recognition. Conventional feature…
