I korthet

This Master's thesis project investigates semantic communications for vehicle and road user detection using foundation models like CLIP and DINOv2. The research aims to compress and transmit task-relevant spatial features over noisy wireless channels, evaluating performance against various baselines and channel conditions.

Ansvarsområden

Build and evaluate a semantic-communication system that extracts spatial features from images using a frozen CLIP-ViT-B/16 or DINOv2-ViT-B/14 model.
Compresses them through a learned linear bottleneck, quantizes and transmits them over a simulated additive white Gaussian noise (AWGN) channel, and reconstructs bounding boxes and class labels with a lightweight decoder.
Review semantic communications, joint source-channel coding (DeepJSCC), foundation models, and JPEG compression.
Extract patch-level features from the selected COCO classes.
Implement the learned bottleneck, quantization, AWGN channel simulation, and lightweight anchor-free detection decoder.
Train the bottleneck and decoder end-to-end with noise injection at random signal-to-noise ratio (SNR) levels.
Compare both foundation-model approaches with a task-specific encoder-decoder and standard baselines such as JPEG.
Analyze results in a communications context, including mean average precision (mAP) versus SNR and per-class performance.

Krav

Pursuing a master’s degree in Electrical Engineering, Computer Science, Telecommunications, or a related field.
Strong programming skills in Python and PyTorch.
Good understanding of deep-learning concepts, including CNNs, transformers, training procedures, and loss functions.
Ability to work independently, design experiments, and critically interpret results.
Fluency in written and spoken English.

Önskade kvalifikationer

Familiarity with object detection (e.g., YOLO, Faster R-CNN, or FCOS), wireless communications (e.g., SNR and AWGN), or pretrained vision models (e.g., CLIP, ViT, or DINOv2) is an advantage.
