Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Image Segmentation

Hey, following problem: I want to generate images from UE4 for a deep learning segmentation task, thus I need pixel precise annotation. As suggested in other posts I am using a SceneCaptureComponent2D with a post process material attached that uses custom render depth / custom stencil. This is all fun and working so far except for the following problem: The segmentation generated suffers from some kind of "image interpolation" best described in this image :

This seems like not much but for gray scale "annotation" this is actually doing a lot of damage for me.

This is the setup of my post process shader:

I already deactivated any form of AA, Bloom, Eye Adaption on the capture component. So if anyone could point me into either direction of the problem causing this effect, or a possible solution to this I would be very grateful!
