load-bearing objection This paper defines LV-OSD as mixed text-image prompt open-set detection and offers a dual-branch model with TPDW weighting and PRM masking, but the abstract supplies no numbers to check whether it works.
LV-OSD: Language-Vision-Complementary Open-Set Object Detection
The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
The authors establish that the Target-guided Prompt Dynamic Weighting module, guided by prior information extracted from the target image, dynamically produces the text and image prompts that best align with the target semantics, achieving precise alignment and effectively reducing the discrepancy between the two modalities, thereby accommodating the LV-OSD setting.
What carries the argument
Target-guided Prompt Dynamic Weighting (TPDW) module that uses target-image priors to set dynamic weights on text and image prompts for modality alignment.
Load-bearing premise
Prior information extracted from the target image is sufficient to determine weights that optimally align text and image prompts.
What would settle it
An ablation experiment in which fixed or uniform prompt weights produce detection accuracy equal to or higher than the full TPDW module on LV-OSD benchmarks would show that the dynamic weighting step does not deliver the claimed alignment benefit.
If this is right
- The dual-branch architecture accepts text prompts, image prompts, or both at the same time.
- Prompt random masking during training prepares the model for arbitrary prompt combinations at inference.
- The weighting step reduces semantic discrepancy among the input image, text prompts, and image prompts.
- Experiments confirm the formulation and the method work on the proposed LV-OSD task.
Where Pith is reading between the lines
- The same image-prior weighting idea could be tested on other vision-language tasks that fuse separate prompt sources.
- Image content might serve as a general reference signal for deciding how much to trust language versus visual prompts.
- Performance when one prompt type is missing or low-quality would reveal whether the dynamic mechanism still functions.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper introduces LV-OSD, a new open-set object detection setting allowing flexible text-based and/or image-based prompts to specify object categories. It proposes the LVDor dual-branch framework that accepts both modalities, constructs Multi-modal Prompts (MPr) per category, introduces the Target-guided Prompt Dynamic Weighting (TPDW) module that uses target-image priors to dynamically weight and align text and image prompts, and adds a Prompt Random Masking (PRM) mechanism during training to simulate arbitrary prompt combinations at test time. The authors assert that extensive experiments confirm both the problem formulation's practicality and the method's effectiveness, with code and prompts to be released.
Significance. If the experimental claims hold, the work addresses a practically relevant extension of open-set detection by supporting mixed language-vision prompts. The TPDW design offers a concrete mechanism for reducing cross-modal discrepancy via target-guided dynamic weighting, and the PRM training strategy is a straightforward way to handle prompt variability. Public release of prompts and code would strengthen reproducibility. The contribution is primarily architectural and engineering-oriented rather than theoretical.
minor comments (2)
- [Abstract] Abstract: the sentence fragment 'which aims to detect the objects of interest. through the given category list' contains a typographical error (extraneous period and incorrect capitalization).
- [Abstract] Abstract: the claim of 'extensive experimental results' is stated without any numerical values, tables, or baseline comparisons in the provided abstract; the full experimental section should be checked for quantitative support of the central effectiveness claim.
Simulated Author's Rebuttal
We thank the referee for the positive assessment of our LV-OSD problem setting and the LVDor framework, including the TPDW and PRM components, and for recommending minor revision. The summary accurately reflects the manuscript's focus on practical mixed-modality prompting for open-set detection.
Circularity Check
No significant circularity detected
full rationale
The paper introduces LV-OSD as a new problem formulation and presents LVDor as a dual-branch architecture with MPr construction, the TPDW module (guided by target-image priors for dynamic prompt weighting), and PRM for training. These are described as engineering design choices whose effectiveness is asserted via experiments. No equations, derivations, fitted parameters renamed as predictions, or self-citation chains appear in the provided text that reduce any claimed result to its inputs by construction. The central claims remain independent of tautological definitions or load-bearing self-references.

Object detection is an important task in computer vision, which aims to detect the objects of interest. through the given category list or query images. In this work, we propose a new problem of language-visual-complementary open-set object detection (LV-OSD), i.e., using the flexible text-based and/or image-based prompts to specify the desired object categories. This setting is more common and practical in real-world applications. For this purpose, we design a dual-branch detection framework, LVDor, which can simultaneously accept both text and image prompts. Specifically, we first build the Multi-modal Prompts (MPr) containing various text descriptions and image samples for each category. Subsequently, to bridge the semantic gap among the input image, text prompts, and image prompts, we design a Target-guided Prompt Dynamic Weighting (TPDW) module. Guided by the prior information of the target image, this module dynamically produces the text and image prompts that best align with the target semantics, achieving precise alignment and effectively reducing the discrepancy between the two modalities, thereby accommodating the LV-OSD setting. We also propose a simple Prompt Random Masking (PRM) mechanism during training to simulate the arbitrary combination of text and/or image prompts in testing. Extensive experimental results verify our problem formulation's reasonability and our method's effectiveness. Prompts and code will be released publicly.
