Visible Mask - Data generation

Question

Visible Mask - Data generation

Opened this issue a month ago · 3 comments

Often it is required to obtain only the visible portion of the mask for the object and thus removing the mask of distractors. How to achieve this?

I am not sure I am following, could share an example?

Sure, for example in the below case I want ground truth mask of "white watering can" behind the yellow duck, then the output mask should be only the visible portion of the "white watering can". Similarly when segmentation mask is generated then it would be great to have an option which only outputs the visible portion of the object and excluding all the distractor mask.

https://github.com/owl-project/NVISII/blob/master/examples/09.meta_data_exporting.py#L125-L139 check this out, this is what you want to save, if you look at the code, when we compute the visibility, we move objects and render them around to get percentage.
