# EPIC-KITCHENS VISOR Benchmark: VIdeo Segmentations and Object Relations Source: [EPIC-KITCHENS VISOR Benchmark: VIdeo Segmentations and Object Relations]() Collection index: [llms.txt]() Data updated: 2026-01-04T05:22:33.796Z Authors: Ahmad Darkhalil, Dandan Shan, Bin Zhu, Jian Ma, Amlan Kar, Richard Higgins, Sanja Fidler, David Fouhey, Dima Damen Published: 2022-09-26T23:03:26.000Z ## Abstract We introduce VISOR, a new dataset of pixel annotations and a benchmark suite for segmenting hands and active objects in egocentric video. VISOR annotates videos from EPIC-KITCHENS, which comes with a new set of challenges not encountered in current video segmentation datasets. Specifically, we need to ensure both short- and long-term consistency of pixel-level annotations as objects undergo transformative interactions, e.g. an onion is peeled, diced and cooked - where we aim to obtain accurate pixel-level annotations of the peel, onion pieces, chopping board, knife, pan, as well as the acting hands. VISOR introduces an annotation pipeline, AI-powered in parts, for scalability and quality. In total, we publicly release 272K manual semantic masks of 257 object classes, 9.9M interpolated dense masks, 67K hand-object relations, covering 36 hours of 179 untrimmed videos. Along with the annotations, we introduce three challenges in video object segmentation, interaction understanding and long-term reasoning.

Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage. - [Spatial contact segmentation on EPIC-VISOR (val)](): Spatial contact segmentation; EPIC-VISOR (val); IOU: 40.2. - [Temporal contact detection on VISOR (val)](): Temporal contact detection; VISOR (val); BC: 66.3. - [Spatial contact segmentation on HOI4D (val)](): Spatial contact segmentation; HOI4D (val); IoU: 50.2. - [Spatial contact segmentation on FEEL (val)](): Spatial contact segmentation; FEEL (val); IoU: 11.1. - [Temporal contact detection on HOI4D (val)](): Temporal contact detection; HOI4D (val); BC: 55.3. - [Temporal contact detection on FEEL (val)](): Temporal contact detection; FEEL (val); BC: 45.2. ## Original sources and implementation [Original paper]() [PDF]() [Implementation]()
