From Web to Pixels: Bringing Agentic Search into Visual Perception

Hugging Face Daily Papers Papers

Summary

This paper introduces WebEye, a benchmark for object localization requiring external knowledge resolution, and Pixel-Searcher, an agentic approach that connects search results to visual annotations.

Visual perception connects high-level semantic understanding to pixel-level perception, but most existing settings assume that the decisive evidence for identifying a target is already in the image or frozen model knowledge. We study a more practical yet harder open-world case where a visible object must first be resolved from external facts, recent events, long-tail entities, or multi-hop relations before it can be localized. We formalize this challenge as Perception Deep Research and introduce WebEye, an object-anchored benchmark with verifiable evidence, knowledge-intensive queries, precise box/mask annotations, and three task views: Search-based Grounding, Search-based Segmentation, and Search-based VQA. WebEyes contains 120 images, 473 annotated object instances, 645 unique QA pairs, and 1,927 task samples. We further propose Pixel-Searcher, an agentic search-to-pixel workflow that resolves hidden target identities and binds them to boxes, masks, or grounded answers. Experiments show that Pixel-Searcher achieves the strongest open-source performance across all three task views, while failures mainly arise from evidence acquisition, identity resolution, and visual instance binding.

Abstract

Researchers introduce WebEye, a benchmark for object localization requiring external knowledge resolution, and Pixel-Searcher, an agent-based approach that connects hidden target identities to visual annotations through search and reasoning.

Visual perception connects high-level semantic understanding to pixel-level perception, but most existing settings assume that the decisive evidence for identifying a target is already in the image or frozen model knowledge. We study a more practical yet harder open-world case where a visible object must first be resolved from external facts, recent events, long-tail entities, or multi-hop relations before it can be localized. We formalize this challenge asPerception Deep Researchand introduce WebEye, anobject-anchored benchmarkwithverifiable evidence,knowledge-intensive queries,precise box/mask annotations, and three task views:Search-based Grounding,Search-based Segmentation, andSearch-based VQA. WebEyes contains 120 images, 473 annotated object instances, 645 unique QA pairs, and 1,927 task samples. We further proposePixel-Searcher, anagentic search-to-pixel workflowthat resolves hidden target identities and binds them to boxes, masks, or grounded answers. Experiments show thatPixel-Searcherachieves the strongest open-source performance across all three task views, while failures mainly arise from evidence acquisition, identity resolution, andvisual instance binding.
