dc.description.abstract | Criminal activity detection from footage, especially in low-light circumstances, offers
a considerable problem due to reduced visibility, noise, and detail loss. In
this research, we present an approach for detecting criminal actions in low-light
videos using deep learning models. The specific difficulty of low-light conditions,
which result in limited visibility and noisy data, is handled using modern video
pre-processing techniques to improve video quality. Our strategy improves video
classification accuracy by using both spatial and temporal information, preserving
essential visual signals. We use transfer learning to adapt pre-trained models such as
VGG-16, MobileNetV2, NASNetMobile, LSTM and a Conv-LSTM so that they can
generalize effectively in low-light settings. The modified UCF Crime dataset simulates
low-light situations, and our results illustrate that the suggested technique
improves detection accuracy while remaining efficient. This study paves the path
for more dependable surveillance systems capable of working in harsh environments.
After working through all these models the best performing model we got was the
ConvLSTM model where we got an accuracy of 77%. | en_US |
