Hi @avinashj,
thanks for the compliment! I actually did work a bit further on the project, specifically on the leaves from the category “NaturalBackground” which would be similar to your dataset.
My idea is to use the model I trained on the “SheetAsBackground” data with fastai and apply transfer learning to it, in order to train the model with the “NaturalBackground” images.
This seems not to work out of the box with fast.ai, as there are not 124 classes but instead 51 classes in the new dataset. I found a way to solve this problem with the help of @PierreO, see how it is done here.
I guess you could take my model and use transfer learning with your own dataset. Let me know how it goes!
