My name is Krzysztof Lis and I am a PhD student at the EPFL Computer Vision Lab of Pascal Fua. I come from Poland and did my master's degree at ETH Zurich. My research concerns visual perception for autonomous cars:

  • detecting unusual and anomalous objects,
  • semantic segmentation,
  • jointly perceiving semantic and 3D information about the scene.

Apart from computer vision, my interests are game development, digital art, fantasy & science-fiction.

Label Grab

Annotation tool for semantic and instance segmentation, with automated help from the GrabCut algorithm implemented in OpenCV .

The algorithm attempts to find the foreground object in a user-selected bounding box. It presents a suggested per-pixel mask, the user can then correct its mistakes and next suggestion will take those into account.

Augmented Unreality

Augmented Unreality is a plugin for Unreal Engine 4 which enables creation of augmented reality applications by displaying a video stream from a camera inside the game and tracking camera position using the ArUco fiducial markers .

I created it as a semester project at ETH Zürich.
