Revolutionizing Entity Detection in Dynamic Media: A Deep Learning Approach
Leveraging Artificial Neural Networks for Enhanced Security and Efficiency in Video Content Analysis
Executive Impact
This paper presents a novel deep learning approach for detecting specific entities within video sequences, focusing on artificial neural networks to identify characters. Our method offers significant improvements in locating target individuals efficiently from both private and public image databases. The proposed classifier holds substantial promise for reinforcing national security systems, particularly in Angola, by integrating with existing databases of target individuals (e.g., disappeared persons, criminals) and video feeds from the Integrated Public Security Centre (CISP). This innovation enhances capabilities for real-time security and intelligence gathering.

Entity Detection Output (Person/No Person)
| Metric | Proposed Approach | Traditional Methods |
|---|---|---|
| Accuracy (AUC) | 67.7% (with SGD) | Lower (e.g., 66% with RMSprop) |
| Robustness to Pose/Attire Changes | Highly effective, identifies targets despite varied clothing, hairstyles, and postures (87-93% sensitivity). |
Prone to failure with significant variations in appearance; often struggles with occlusion or unusual positions. |
| Efficiency in Dynamic Media | Designed for video sequences, leverages temporal features for robust detection. |
Primarily image-based; less effective in dynamic, real-time video analysis without significant overhead. |
| False Positives | Instances observed, particularly with distant characters or similar-looking individuals. |
Higher rates due to simpler feature extraction and lack of temporal context. |
| False Negatives | Occurs when specific features are obscured (e.g., head coverings) or during rapid, complex movements. |
Common when target is partially visible or in non-standard poses. |
Case Study: National Security Enhancement in Angola
The proposed classifier offers a significant opportunity for Angola to strengthen its national security. By integrating with the **Integrated Public Security Centre (CISP)** and its existing databases of target individuals (e.g., disappeared persons, criminals), the system can provide efficient, real-time detection in video sequences. This capability can drastically reduce investigation times and improve proactive security measures, making public spaces safer and supporting law enforcement efforts with advanced AI-powered surveillance.
