To create a system robust to diverse lighting environments.

Main Methods:

Utilized a time-of-flight (ToF) camera for data acquisition.
Implemented a slide window weight fusion (SWWF) method for image fusion.
Extracted joint features from depth and intensity data.
Applied four machine learning algorithms for object recognition.

Main Results:

Achieved a 0.778 intersection over union (IoU) for target localization.
K-Nearest Neighbor (KNN) achieved the highest classification accuracy at 98.01%.
The framework demonstrated resilience to varying illumination conditions.

Conclusions:

The proposed fusion framework effectively improves object detection and recognition.
The SWWF method provides accurate localization and robust classification.
This approach is suitable for applications requiring reliable object identification under challenging lighting.
