Abstract In automated video surveillance applications, detecting abnormal human activity is incredibly difficult to classify them. The automatic detection of aberrant human activity in a surveillance system was resolved in our proposed work. The videos are first turned into frames, and keyframes from a batch of frames are extracted using fuzzy logic. Secondly, the features are retrieved from the keyframes using a pre-train convolutional neural network (CNN) through transfer learning. Finally, to recognize anomalous activity from video, the collected features are loaded into a Long-Short Term Memory (LSTM) based recurrent network. Two benchmark datasets were used to evaluate the proposed methodology: the UCF50 and the UCF-crime, with our model achieving 95.04% and 49.04% accuracy, respectively. Using the same data set, the experimental findings are compared to conventional detection approaches which suggest that our proposed model outperforms the other approaches that were compared.
