Learning advice on knowledge related to object detection?

Part 1 (2020) Non-beginner

Through the study of fastai course, I have gained a deep understanding of classification and segmentation. However, at the present stage, the application of object detection is very wide, but I have little understanding of its relevant contents.Is there any good information to promote the learning of object detection knowledge? Thanks~

This is a great resource:


(if you only interested in the newest stuff be sure to look at part 3/4)

I found this article to be great: http://www.telesens.co/2018/03/11/object-detection-and-classification-using-r-cnns/#ITEM-1455-0

Not quite sure about your question. But I would say to look at this, it is a good start:

Hey, there’s a previous iteration of the course where Jeremy talks about it. Check this out Object detection 1 , Object detection 2 and finally papers with code. I think if you try replicate the examples and review the papers with specific goals in mind you’ll probably be able to implement it in your own use case.

I want to do fastai v2 implementations of object detection algorithms such as yolo v3 and ssd variants. Anyone interested in doing a study group around object detection algorithms?

@zevarela here’s some starter code for object detection I did (this used the SSD technique from v1, has a few issues but if you check the discussion forum there’s someone who’s been working on it, I’d focus on it for the data block :slight_smile: )

Wow! Thanks a lot! This seems to be exactly what I was looking for!

FWIW, let me plug my own blog post on the topic. :smile: https://machinethink.net/blog/object-detection/

@zevarela did anyone ever join you to do this? I’m very interested. I’ve been looking at and trying to dive into @muellerzr 's notebook for the last several days which I’m running into issues applying to a different dataset. It seems I’m not alone based on other posts and it’d be good to get your feedback and maybe we can work together.

Honestly I would recommend IceVision instead of that notebook, and eventually I’ll be updating that notebook to utilize their library. It’s much better integrated with the api :slight_smile:

OK. I came across IceVision. I had bookmarked that to come back to but maybe I should re-prioritize. Thanks
