EfficientDet for Edge-Aware Semantic Segmentation

Assignment for Object Detection during VR course at MIMUW in 2022, graded for 10 / 10
Beware as repo is ~400MB large, as it consists of two fully trained models
Author: Marcin Mazur

Code Structure

  • models - best model checkpoints.
  • plots - plots generated during trainings.
  • report - report with techinques, summary of my work (mm418420.pdf).
  • src source files.
    • data - module for data processing.
    • utils - module for useful help functions.
  • efficient_det.ipynb - notebook with logs from best run.

Performance

Tests should be fast ~1min, and can be run with pytest command.
Full training (10 epochs) takes ~3min on 4GB GPU.

Environment

Project was developed on:

  • python 3.9.7
  • pytorch 1.11.0

Task description

In this task - one should implement a part of the one of the state-of-the-art NN architecture for dense predictions - EfficientDet - called the BiFPN feature combinator. Then one should use the features from the FPN as an input to two heads: one for an person segmentation (single class) and other for an edge detection. This network should be trained on the PennFundan dataset with traditional augmentations.
