Less is More: Concise Retrieval and Critic-based Re-ranking for Composed Image Retrieval

Read the original on arXiv AI →

The paper introduces Less-is-More CIR, a two-stage, training-free framework for zero-shot composed image retrieval. First, it generates concise target-oriented captions that keep only the most discriminative modification semantics, reducing semantic noise. Second, a critic re-ranking module evaluates retrieved candidates for modification consistency and reference preservation, improving retrieval performance.

Preserve-and-Compose Training for Composed Image Retrieval

The paper introduces Preserve-and-Compose Training (PACT) for composed image retrieval, a task where a query image is modified by a textual instruction while preserving visual content from a reference image. PACT learns from image–text–text triplets, using target captions for supervision and visual evidence from the source image to maintain relevant details, without requiring target images or gallery updates. The authors also propose Chord scoring, which blends target similarity with source-relative directional agreement in a frozen image space, and demonstrate that this combined approach yields strong retrieval performance across multiple zero-shot CIR benchmarks and various backbones.

DiCE-CIR: Direct Composition Learning for Efficient Zero-Shot Composed Image Retrieval

Zero-shot composed image retrieval (ZS-CIR) aims to retrieve a target image from a multimodal query consisting of a reference image and an edit text describing the desired modification. Recent ZS-CIR studies have relied on projection-based methods that map a reference image into pseudo-word tokens in the text embedding space.

FlowCIR: Semantic Transport via Flow Matching for Zero-Shot Composed Image Retrieval

Zero-shot composed image retrieval (ZS-CIR) aims to retrieve a target image by editing a reference image with a natural-language instruction, without relying on domain-specific annotated triplets. Most existing ZS-CIR methods rely on textual inversion to translate the reference image into pseudo-text tokens and then compose them with the instruction via simple concatenation in the text space, which can be lossy and brittle for fine-grained semantics.
