Summary
This study introduces a three-class face mask compliance detection system using MobileNetV3, achieving 98.90% accuracy. The advanced model effectively identifies correct, improper, and no mask usage, outperforming traditional methods in surveillance environments.
Area of Science:
- Computer Science
- Artificial Intelligence
- Machine Learning
Background:
- Face mask compliance is crucial for public health surveillance.
- Traditional binary mask detection methods often overlook nuanced compliance levels.
- Developing robust systems for multi-class mask detection is essential for health-sensitive environments.
Purpose of the Study:
- To develop and evaluate a multi-class face mask compliance detection system.
- To address the limitations of binary classification by including 'improper mask use'.
- To compare the proposed system's performance against existing state-of-the-art models.
Main Methods:
- A Deep Convolutional Neural Network (DCNN) based on MobileNetV3 was employed.
- The model was adapted with a lightweight fully connected layer and Squeeze-and-Excitation (SE) blocks.
- A balanced, custom-curated dataset of 2,079 images was used with a 70:15:15 train-validation-test split.
Main Results:
- The MobileNetV3 system achieved 98.90% accuracy and an F1-score of 0.989.
- The three-class system (correct, improper, no mask) demonstrated superior performance.
- The model proved competitive or superior to MobileNetV2, VGG16, and YOLO-based models.
Conclusions:
- The proposed MobileNetV3 system offers a highly accurate solution for multi-class face mask compliance monitoring.
- The inclusion of improper mask use enhances the system's practical applicability in surveillance.
- Future work includes real-time monitoring and explainable AI integration for improved implementation.

01:22Force Classification
Forces play a crucial role in the study of physics and engineering. They are essential in describing the motion, behavior, and equilibrium of objects in the physical world. Forces can be classified based on their origin, type, and direction of action.
Contact and non-contact forces are two of the most widely used categories of forces. As the name suggests, contact forces require physical contact between two objects to act upon each other. Examples of contact forces include frictional,...

01:19Masking and Demasking Agents
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on the metal...
