FairRSFM: A Biome-Aware Benchmark and Debiasing Framework for Remote Sensing Foundation Models
Md Aminur Hossain, Omkumar Vaghasiya, Rajeev Ranjan Dwivedi +2
Remote sensing foundation models (RSFMs) are commonly evaluated using aggregate metrics, which can hide systematic performance disparities across ecological regions. We introduce F…
Near-field Ultrafast Nondiffractive Laser Nanoscale Cutting of Glass with Quasi-null Interface Roughness
Rajeev Dwivedi, Anton Rudenko, Guodong Zhang +5
Generally, ultrafast laser glass dicing is governed by explosive material removal, which restricts the achievable surface roughness. Here we report single-step dicing of aluminosil…
Query-Aware Token Budgeting for Efficient Late-Interaction Visual Document Retrieval
PS Rishi, Rajeev Ranjan Dwivedi, Vinod K Kurmi
Late-interaction visual document retrievers preserve fine-grained page evidence by storing many token embeddings per page, but the resulting storage and query-time interaction cost…
AlignJEPA: Predictive Vision-Language Alignment for Remote Sensing Foundation Models
Md Aminur Hossain, Omkumar Vaghasiya, Rajeev Ranjan Dwivedi +2
Remote sensing (RS) foundation models provide transferable Earth observation representations across sensors, resolutions, and geographies, yet most remain weakly aligned with natur…
Histogram Assisted Quality Aware Generative Model for Resolution Invariant NIR Image Colorization
Abhinav Attri, Rajeev Ranjan Dwivedi, Samiran Das +1
We present HAQAGen, a unified generative model for resolution-invariant NIR-to-RGB colorization that balances chromatic realism with structural fidelity. The proposed model introdu…
