Idea
A robust scene-level sketch-based image retrieval model improving accuracy for designers, artists, and visual search platforms.
Research Paper
Core Innovation
This paper introduces a novel training objective that integrates pre-training, encoder design, and loss formulation to handle ambiguity and noise in free-hand scene sketches. It significantly improves retrieval accuracy without increasing model complexity. The approach sets new state-of-the-art results on major sketch-based image retrieval benchmarks.

Research Paper Overview
Back To The Drawing Board: Rethinking Scene-Level Sketch-Based Image Retrieval
Summary
The paper addresses the challenge of retrieving natural images that match the semantics and spatial layout of free-hand sketches at the scene level. It highlights the inherent ambiguity and noise in real-world sketches and proposes a robust training objective combining pre-training, encoder architecture, and loss formulation. The approach achieves state-of-the-art results on FS-COCO and SketchyCOCO datasets without added model complexity, emphasizing the importance of training design and improved evaluation in cross-modal retrieval.
