Detectron2 Overview

Detectron2 is a cutting-edge object detection framework developed by Facebook AI Research (FAIR). It simplifies the process of building, training, and deploying object detection models. By providing modular components and pre-implemented state-of-the-art algorithms, Detectron2 enables efficient experimentation and development in the field of computer vision.

Retinanet Baseline

The COCO-Detection/retinanet baseline is a specific object detection model architecture available within Detectron2. RetinaNet is a one-stage object detection model known for its efficient speed and competitive accuracy. It's especially suited for detecting objects of varying scales and sizes, making it a suitable choice for medical image analysis like tumor detection in brain MRI images. The COCO-Detection baseline further fine-tunes the RetinaNet architecture on the COCO dataset, which is a widely-used benchmark for object detection tasks.

Web Application

The user-friendly web application powered by Streamlit simplifies the utilization of the tumor detection model. Users can effortlessly upload their brain MRI images and instantly visualize the detected tumor regions.

Dataset

The dataset used in this project is sourced from Roboflow Universe. This dataset consists of axial brain MRI images annotated with tumor regions.

Project Structure

• train: This directory contains files for training the model. The trained model weights are saved in the /train/output/directory, eliminating the need for retraining. The project's training progress, such as loss and validation plots, can be found here as well. The selected model weights for deployment were taken from epoch number 3000 based on the provided training and validation plots.
