SaMer reduces vision-language token overhead while preserving object-level retrieval precision
Vision-language retrieval systems face a scaling bottleneck: preserving fine-grained visual details while keeping inference costs tractable. SaMer addresses this by intelligently merging image tokens into representative clusters during training, using object-level supervision as a guide without requiring detectors at inference time. The approach maintains the late-interaction retrieval interface that enables precise matching between queries and visual regions, solving a practical constraint for production multimodal search. This matters because dense token representations currently force tradeoffs between retrieval quality and computational efficiency, a friction point as vision-language models scale to real-world applications.58
