Annotation clarification #31

Closed souravehere closed 2 years ago

souravehere commented 3 years ago

some bbox annotation contains negative values. for instance, 10, -5, 200, 170, .997. Could you please clarify why negative values in a box coordinates?

example: Data/train/3025/spoof/029572_BB.txt

here's another error: Data/train/3329/spoof/004046_BB.txt doesn't have any annotations at all. it's an empty file

Sure, this situation exists because these box coordinates are produced by the CNN model.

How do you take care of these missing and negative values ? Do you take the whole image as input ?

Arvindia commented 3 years ago

@Davidzhangyuanhan is there any csv file for all the attributes like in original CelebA dataset?
