A Novel Discrete Fractional Complex Hadamard Transform for Medical Image Encryption

ICASSP 2024accepted

This paper introduces a new discrete fractional complex Hadamard transform (FCHT) and its generalized form, the multiple-parameter FCHT (MFCHT). The MFCHT is applied to the medical image encryption. Both subjective observations and objective evaluations are conducted to validate the effectiveness of…

MSN-net: Multi-Scale Normality Network for Video Anomaly Detection

ICASSP 2023accepted

Existing unsupervised video anomaly detection methods often suffer from performance degradation due to the overgeneralization of deep models. In this paper, we propose a simple yet effective Multi-Scale Normality network (MSN-net) that uses hierarchical memories to learn multi-level prototypical spa…
