The authors propose VPS, which combines two operations: grid_search inspects a regular grid of image tiles in parallel using question-conditioned sub-agents, and zoom_in adaptively selects a precise or merged region for higher-resolution inspection.
Parallel tile inspection and adaptive zoom improve high-resolution visual search
A new framework, VPS, uses question-conditioned tile readers and a learned zoom controller to outperform sequential zoom-only search across five benchmarks and three model sizes.
