MAMA Net: Multi-scale Attention Memory Autoencoder Network for Anomaly Detection

Yurong Chen, Hui Zhang, Yaonan Wang, Yimin Yang, Xianen Zhou, Q.M. Jonathan Wu
2020 IEEE Transactions on Medical Imaging  
paper, we propose a Multi-scale Attention Memory with hash addressing Autoencoder network (MAMA Net) for anomaly detection.  ...  First, to overcome a battery of problems result from the restricted stationary receptive field of convolution operator, we coin the multi-scale global spatial attention block which can be straightforwardly  ...  MULTI-SCALE ATTENTION HASH MEMORY AUTOENCODER A.  ...

An Exploratory Analysis on Visual Counterfeits using Conv-LSTM Hybrid Architecture

Mohammad Farukh Hashmi, B Kiran Kumar Ashish, Avinash G. Keskar, Neeraj Dhanraj Bokde, Jin Hee Yoon, Zong Woo Geem
2020 IEEE Access  
This temporal-detection pipeline compares very minute visual traces on the faces of real and fake frames using Convolutional Neural Network (CNN) and stores the abnormal features for training.  ...  The proposed algorithm and designed network set a new benchmark for detecting the visual counterfeits and show how this system can achieve competitive results on any fake generated video or image.  ...  The network is loaded with the face detection model through Multi-Cascaded Convolutional Network (MTCNN) architecture.  ...
