Fig. 3From: Egocentric vision-based detection of surfaces: towards context-aware free-living digital biomarkers for gait and fall risk assessmentSample patches from MAGFRA-W dataset. Outdoor patches were cropped at (267,0) and (1200,0) from the \(1920\times 1080\) outdoor frames during gait. \(1080\times 1080\) regions were cropped from upper left and right corners for indoor scenes. These dimensions were carefully selected to be compatible with the datasets used to train EgoTerrainNet-Outdoor and -IndoorBack to article page
