The Segmenting and Tracking Every Pixel (STEP) benchmark consists of 2 training sequences and 2 test sequences. It is based on the MOTChallenge and Multi-Object Tracking and Segmentation (MOTS) benchmark. This benchmark extends the annotations to the STEP task. To this end, we added dense pixelwise segmentation labels for every pixel. In this benchmark, every pixel has a semantic label and all pixels belonging to the most salient object class, pedestrian, have a unique tracking ID. We evaluate submitted results using the Segmentation and Tracking Quality (STQ) metric. This benchmark is part of the ICCV21-Workshop Segmenting and Tracking Every Point and Pixel.
