A question about .sm file about affordance-net HOT 6 OPEN

The segmentation groundtruth from Pascal dataset is only binary. If you don't care about the object parts/affordances, then you can simply just treat all masks equally. In this case, it becomes the instance segmentation problem, which is less complicated. Each .sm file is for one object and keeps the affordance IDs that this object has.

@nqanh Thanks! But I still don't understand, for pascal_voc dataset, I find segmentationclass only have 2913 .png less than train samples. If I want use it to affordanceNet and don't care about the object parts, What should I do?

And about your dataset(IIT), I download the IIT_Affordances_2017dataset. Can you tell me how to deal with it to get dataset like yours? I find the dataset don't have .png. I'm really anxious with it! I'll be appreciate if you have time to answer it

If you don't care about the object parts, then in your mask groundtruth, you'll have only 2 classes (background + foreground). If you prepare your data correctly, then AffordanceNet code works fine with 2 classes. You can visualize the groundtruth to understand more (there are already some discussions and code in other issues).

The IIT_Affordances_2017 does has the image files :)

@litingsjj and please change the number of classes in proto.txt files
