Object Detection is a Computer Vision task that aims to detect and classify individual objects in a scene or image. There are various model architectures for Object Detection, but the two most common are region proposal (e.g. The Lightning Flash team recently released a new exciting integration with the IceVision Object Detection library that enables dozens of new state-of-the-art backbones that can be fine-tuned and inference just a few lines of code. We participated in the Kaggle: COVID19 detection/classification challenge to showcase the new integration, which presents a realistic and challenging dataset of CT scans from over six thousand patients. The recent Kaggle: COVID19 detection/classification aims to facilitate medical screening and eventually assist medical experts/doctors with making diagnoses.
