Transformer-Aided Underwater Object Tracking

Duration: October 2022 – January 2023
Type: Computer Vision Research Project

This project focused on enhancing object tracking precision in underwater environments using transformer-based techniques. The challenging aspect of this work was dealing with light-constrained conditions that are typical in underwater scenarios, where traditional tracking methods often fail.

Project Objectives:

Develop robust object tracking algorithms for underwater environments
Address challenges posed by limited lighting conditions
Implement transformer architectures for improved tracking performance
Achieve measurable improvements in tracking precision

Key Achievements:

Enhanced Tracking Precision: Achieved a 2.5% improvement in tracking accuracy compared to baseline methods
Transformer Integration: Successfully adapted transformer architectures for underwater object tracking
Light Constraint Handling: Developed specialized techniques for low-light underwater conditions
Real-world Application: Demonstrated practical applicability in actual underwater scenarios

Technical Approach:

The project leveraged the attention mechanisms inherent in transformer architectures to better focus on relevant object features despite challenging lighting conditions. Key innovations included:

Custom transformer encoder-decoder architectures optimized for underwater imagery
Advanced preprocessing techniques for light enhancement
Temporal consistency mechanisms for stable tracking across frames
Multi-scale feature extraction for robust object representation

Challenges Addressed:

Light Attenuation: Underwater environments significantly reduce light availability
Color Distortion: Water causes color shifts that affect object appearance
Motion Blur: Underwater currents create additional motion complexities
Scale Variations: Objects appear different at various depths

Technologies Used:

Python
PyTorch
OpenCV
Transformer architectures (Vision Transformer variants)
Underwater imaging datasets
Custom data augmentation techniques

Applications:

This research has potential applications in:

Marine biology research
Underwater robotics
Submarine navigation systems
Ocean exploration and monitoring
Aquaculture monitoring systems

Caption photos easily. On the left, a road goes through a tunnel. Middle, leaves artistically fall in a hipster photoshoot. Right, in another hipster photoshoot, a lumberjack grasps a handful of pine needles.

This image can also have a caption. It's like magic.

You can also put regular text between your rows of images. Say you wanted to write a little bit about your project before you posted the rest of the images. You describe how you toiled, sweated, bled for your project, and then… you reveal its glory in the next row of images.

You can also have artistically styled 2/3 + 1/3 images, like these.

The code is simple. Just wrap your images with <div class="col-sm"> and place them inside <div class="row"> (read more about the Bootstrap Grid system). To make images responsive, add img-fluid class to each; for rounded corners and shadows use rounded and z-depth-1 classes. Here’s the code for the last row of images above:

<div class="row justify-content-sm-center">
  <div class="col-sm-8 mt-3 mt-md-0">
    {% include figure.liquid path="assets/img/6.jpg" title="example image" class="img-fluid rounded z-depth-1" %}
  </div>
  <div class="col-sm-4 mt-3 mt-md-0">
    {% include figure.liquid path="assets/img/11.jpg" title="example image" class="img-fluid rounded z-depth-1" %}
  </div>
</div>
