Labeling Indoor Scenes with Fusion of Out-of-the-Box Perception Models

no code implementations17 Nov 2023 Yimeng Li, Navid Rajabi, Sulabh Shrestha, Md Alimoor Reza, Jana Kosecka

We aim to develop a cost-effective labeling approach to obtain pseudo-labels for semantic segmentation and object instance detection in indoor environments, with the ultimate goal of facilitating the training of lightweight models for various downstream tasks.

Learning-Augmented Model-Based Planning for Visual Exploration

no code implementations15 Nov 2022 Yimeng Li, Arnab Debnath, Gregory Stein, Jana Kosecka

Our approach surpasses the greedy strategies by 2. 1% and the RL-based exploration methods by 8. 4% in terms of coverage.

Self-supervised Pre-training for Semantic Segmentation in an Indoor Scene

no code implementations4 Oct 2022 Sulabh Shrestha, Yimeng Li, Jana Kosecka

Given the spatial and temporal consistency cues used for pixel level data association, we use a variant of contrastive learning to train a DCNN model for predicting semantic segmentation from RGB views in the target environment.
