Sky2Ground: A Benchmark for Site Modeling under Varying Altitude
Zengyan Wang, Sirshapan Mitra, Rajat Modi +2
We introduce Sky2Ground, a three-view dataset designed for varying altitude camera localization, correspondence learning, and reconstruction. The dataset combines structured synthe…
ProDiG: Progressive Diffusion-Guided Gaussian Splatting for Aerial to Ground Reconstruction
Sirshapan Mitra, Yogesh S. Rawat
Generating ground-level views and coherent 3D site models from aerial-only imagery is challenging due to extreme viewpoint changes, missing intermediate observations, and large sca…
RobustGait: Robustness Analysis for Appearance Based Gait Recognition
Reeshoon Sayera, Akash Kumar, Sirshapan Mitra +2
Appearance-based gait recognition have achieved strong performance on controlled datasets, yet systematic evaluation of its robustness to real-world corruptions and silhouette vari…
GaitCrafter: Diffusion Model for Biometric Preserving Gait Synthesis
Sirshapan Mitra, Yogesh S. Rawat
Gait recognition is a valuable biometric task that enables the identification of individuals from a distance based on their walking patterns. However, it remains limited by the lac…
Stable Mean Teacher for Semi-supervised Video Action Detection
Akash Kumar, Sirshapan Mitra, Yogesh Singh Rawat
In this work, we focus on semi-supervised learning for video action detection. Video action detection requires spatiotemporal localization in addition to classification, and a limi…
