What about Object Detection?

[Jyothiraditya-Payavula]

Hey @mrdbourke,

Firstly you have curated an excellent course. So kudos on that.

But I'm kinda pissed off as the course doesn't feature anything about Object Detection. Right now, I'm planning to start an project which requires Object Detection but, don't know how any of that works,

Is object detection different from image classification, in terms of training it using Keras and etc ?

If possible could you provide us with some resources that could help us build object detection models, because I had a difficult time finding any.

And also, no matter what the resource you share, We'd like to learn this Object detection teached by you, so I (and many other students) hopefully are expecting a future potential course or a YouTube video series

We would much appreciate it and also there's great scarcity of tutorials on this topic right now.

Have a great day !!

I also searched for object detection and OCR models, there are some good papers that shows models architectures for that:
https://arxiv.org/pdf/1506.01497.pdf,
https://arxiv.org/pdf/1704.03549v4.pdf
But is possible to use RPN in TF without creating own layers from scratch or subclassing and tinkering with existing ones?

Hey @AdityaNaidu2k2,

Thank you for the kind words!

As for now, there's no plans to add object detection to the current course (it's already far long enough).

Though there may be more through a tutorial on YouTube/ZTM in the future.

In the meantime, I'd check out the TensorFlow object detection API: https://github.com/tensorflow/models/tree/master/research/object_detection

There are a lot of helpful resources on that page.

Also, TensorFlow Hub has a fair few object detection models ready to use: https://www.tensorflow.org/hub/tutorials/object_detection

Finally, Pyimagesearch is another great place for object detection tutorials with TensorFlow: https://www.pyimagesearch.com/category/object-detection/

And @lukbast, I'm not sure what RPN is? But for all available pre-built TensorFlow layers, see the docs here: https://www.tensorflow.org/api_docs/python/tf/keras/layers, if it's not there, subclassing is your next option
