The pith
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
The reading
What carries the argument
The cross-modality feature alignment space (CFAS) starts with LiDAR points projected into the camera image; the sparse depth map is densified by a 7-by-7 max-pooling window, and depth gradients in four directions are concatenated to form a depth variation map. The heterogeneous agent feature alignment (HAFA) module concatenates camera features with that depth variation map and applies a convolution-plus-activation to produce an information-attention map that gates which modality each agent relies on. The aligned features are then lifted into bird's-eye view using depth-based scattering and fused across agents with a transformer encoder, the same structure used in prior intermediate-fusion cooperative perception.
What would settle it
Collect field measurements of calibration drift, vibration, and synchronization errors from a deployed infrastructure camera/LiDAR suite over several months, build a test set whose noise matches those measured distributions, and compare AgentAlign against standard intermediate fusion on it; if the method's margin shrinks to within a few AP points, the claimed real-world robustness is not established.
Extended reading notes
Core claim
The paper's central claim is that multi-sensor misalignment in multi-agent perception can be absorbed at the feature level rather than corrected at the sensor level. A cross-modality feature alignment space (CFAS), built by projecting LiDAR into dense depth maps and adding depth-gradient variation, gives camera and LiDAR features a common representation. A heterogeneous agent feature alignment mechanism (HAFA) then learns an information-attention map that dynamically reweights the modalities for each agent, down-weighting whichever stream is corrupted by noise. Under multifactorial noise this restores cooperative detection accuracy, and the paper reports state-of-the-art results on V2X-Real and on its introduced V2XSet-Noise dataset.
Load-bearing premise
The central claim rests on the assumption that the synthetic noise models used to build V2XSet-Noise (sinusoidal wind vibration at 2 Hz, uniform calibration perturbations inside ±0.5 degrees and meters, 0.1 s synchronization delay, and systematic errors inside ±0.1) match the distribution of real sensor misalignment in deployed vehicle-to-everything systems.
Editorial extensions
If this is right
- If the reported gains hold, infrastructure installation tolerances can be relaxed: cameras and LiDARs no longer need frequent manual recalibration to keep cooperative perception accurate.
- The V2XSet-Noise benchmark provides a controlled way to test how any cooperative perception method degrades under calibration error, vibration, time-sync lag, distortion, and systematic bias.
- The CFAS depth-variation representation is a reusable building block for any camera-LiDAR fusion task with sparse depth, not only V2X.
- HAFA's gating could be read as a reliability estimate, potentially useful for deciding which agents' data to transmit under bandwidth constraints.
Reading between the lines
- The paper's noise magnitudes are synthetic and untested against field measurements, so the practical size of the gain may depend on how well those ranges match a specific deployment site.
- If HAFA learns to downweight a modality under misalignment, the same attention could be exposed as an interpretable sensor-health signal for diagnostics.
- The method's benefit is demonstrated on detection only; tracking and prediction pipelines that consume these features might not inherit the full gain.
Editorial analysis
A structured set of objections, weighed in public.
Referee Report
Summary. The paper proposes AgentAlign, a cooperative perception framework that aligns multi-modal features across heterogeneous agents (vehicles and infrastructure) to be robust to sensor misalignment and multifactorial noise. The method introduces a cross-modality feature alignment space (CFAS) that densifies projected LiDAR depth and computes depth gradients, plus a heterogeneous agent feature alignment (HAFA) mechanism that learns an information-attention map to weight camera and LiDAR features. The authors construct a V2XSet-Noise dataset by applying hand-crafted noise models (calibration error, wind vibration, camera distortion, LiDAR motion distortion, time asynchrony, systematic error) to V2XSet and OPV2V, and evaluate on V2X-Real, noisy OPV2V, and V2XSet-Noise, reporting state-of-the-art AP numbers. The central claim is that AgentAlign achieves SOTA performance on real-world multifactorial noise benchmarks.
Significance. If the reported results are correct and reproducible, the work addresses a real and underexplored problem: fragile inter-agent sensor correlations under realistic misalignment. The proposed CFAS and HAFA modules are simple and potentially generalizable, and the V2XSet-Noise dataset could serve as a useful robustness benchmark. However, the paper currently provides no code, no data, no error bars, and no ablations on the real dataset that match the headline numbers, which severely limits the verifyability of the claims. The core architectural ideas deserve consideration, but the evidence presented is not yet at the standard required for publication.
major comments (4)
- [§4.3, Table 1 vs §4.4, Table 4] The headline SOTA claim is internally contradicted by the paper's own ablation. Table 1 reports the complete AgentAlign model at 62.6% AP@0.3 and 60.4% AP@0.5 on V2X-Real, while Table 4 reports the full configuration (Cam. + Depth Agg. + Depth Var. + HAFA) at 49.9% AP@0.3 and 38.4% AP@0.5 on the same dataset. No difference in evaluation split, noise injection, checkpoint selection, or metric definition is stated. Both numbers cannot describe the same configuration under the same protocol. The authors must reconcile this discrepancy, explain any protocol difference, and report which number is the actual result for the full model.
- [§3.5 and §4.2 (V2XSet-Noise)] The simulated noise evaluation is only as meaningful as the realism of the noise models. The parameters (2 Hz sinusoidal vibration, uniform calibration perturbations of ±0.5° and ±0.5 m, 0.1 s synchronization delay, systematic errors in ±0.1) are chosen by the authors without validation against field measurements or an established benchmark. Moreover, the method is explicitly designed to counter these specific noise types, so the V2XSet-Noise results do not provide independent evidence of real-world robustness. The real-world V2X-Real results would supply that evidence, but they are called into question by the Table 1/Table 4 contradiction.
- [§4.3, Tables 1–3] The comparison tables omit the strongest cited multi-modal cooperative perception methods. For instance, HM-ViT [26] and V2X-ViT [30], both cited in the paper, are not included in any comparison, and CooperFuse [37] is also absent. Additionally, no error bars or multiple-run statistics are provided, so the reported improvements (e.g., 62.6 vs 58.6 on V2X-Real) cannot be assessed for statistical significance. The authors should add comparisons to these relevant methods and report variance.
- [§4.1 (Implementation Details)] The training protocol is underspecified. The paper states that the LiDAR and camera streams are trained separately and then HAFA is trained for 10 epochs, but it does not report the total training schedule, learning rates, batch size, optimizer, number of agents during training, or the exact data split (train/val/test) for V2XSet-Noise and V2X-Real. Without these details, the experiments are not reproducible, especially since code and data are promised only for future release.
minor comments (6)
- [§4.4 heading] The heading reads "Abalation Studies" and should be corrected to "Ablation Studies."
- [§3.5 heading] The heading "Time Sychronization" contains a typo; it should be "Time Synchronization."
- [§3.5, Calibration Error] The phrase "can be particularly series" should be "can be particularly serious."
- [§4.2] The paper uses AP@0.3/0.5 for V2X-Real but AP@0.5/0.7 for V2XSet-Noise and OPV2V. The choice of different IoU thresholds across datasets should be justified, as it makes cross-dataset comparisons confusing.
- [Supplementary, Eq. (2)] In the supplementary, Eq. (2) uses a notation with fXc and fXl that is not standard; this is likely a typographical artifact. Please define all symbols consistently.
- [References] Several references are incomplete or inconsistent (e.g., [5] formats authors as "Wen Yang; Zheng Gong; ..." with semicolons). The authors should verify the reference list.
Circularity Check
No derivation-level circularity: the headline result is anchored by an external real-world benchmark; only the simulated-noise evaluation is partially self-referential.

[Section 3.5 (V2X Multifactorial Noise) and Section 4.2 (Evaluation and Dataset)]
"To evaluate the impact of different types of noise and assess the robustness of AgentAlign, we constructed a new dataset, V2XSet-Noise, based on simulated V2XSet[30] to explicitly account for real-world sensor noise in V2X communication scenarios. ... All noise is added in a controlled manner, resulting in a total of 11,447 frames in our dataset."
The V2XSet-Noise benchmark is generated by the authors from V2XSet, also from the same group, using corruption types and magnitudes chosen in this paper (e.g., +/-0.5 degree and +/-0.5 m calibration perturbations, 2 Hz sinusoidal vibration, 0.1 s asynchrony, +/-0.1 systematic errors). AgentAlign's CFAS and HAFA modules are explicitly designed to counter exactly these misalignment types, so the simulated-benchmark robustness claim re-tests the paper's own assumptions rather than an independently specified corruption distribution. This is evaluation-level self-reference, not a derivation where an output equation reduces to an input by construction, and the V2X-Real external benchmark anchors the central SOTA claim, so the severity is low.
full rationale
I walked the claimed derivation chain: multi-modal feature extraction, CFAS projection and depth-variation construction, HAFA attention-based alignment, multi-agent fusion, and evaluation on V2X-Real, V2XSet-Noise, and noisy OPV2V. No equation in the method is defined in terms of the target metric; no fitted parameter is renamed as a prediction; no load-bearing uniqueness theorem or ansatz is imported from self-citations. Citations to prior work by the same group are uses of public datasets and baselines (V2X-Real, OPV2V, HM-ViT) and are externally checkable. The only partially circular element is the V2XSet-Noise benchmark, whose noise model is authored in this paper; but because the headline comparison on V2X-Real is an independent external benchmark, the central state-of-the-art claim has independent content. The apparent inconsistency between Table 1 (62.6/60.4 AP) and Table 4 (49.9/38.4 AP) for the full model on V2X-Real is a consistency and correctness concern, not a circularity step, because it does not exhibit a reduction of an output to an input by construction; accordingly it is not scored here.

Cooperative perception has attracted wide attention given its capability to leverage shared information across connected automated vehicles (CAVs) and smart infrastructures to address sensing occlusion and range limitation issues. However, existing research overlooks the fragile multi-sensor correlations in multi-agent settings, as the heterogeneous agent sensor measurements are highly susceptible to environmental factors, leading to weakened inter-agent sensor interactions. The varying operational conditions and other real-world factors inevitably introduce multifactorial noise and consequentially lead to multi-sensor misalignment, making the deployment of multi-agent multi-modality perception particularly challenging in the real world. In this paper, we propose AgentAlign, a real-world heterogeneous agent cross-modality feature alignment framework, to effectively address these multi-modality misalignment issues. Our method introduces a cross-modality feature alignment space (CFAS) and heterogeneous agent feature alignment (HAFA) mechanism to harmonize multi-modality features across various agents dynamically. Additionally, we present a novel V2XSet-noise dataset that simulates realistic sensor imperfections under diverse environmental conditions, facilitating a systematic evaluation of our approach's robustness. Extensive experiments on the V2X-Real and V2XSet-Noise benchmarks demonstrate that our framework achieves state-of-the-art performance, underscoring its potential for real-world applications in cooperative autonomous driving. The controllable V2XSet-Noise dataset and generation pipeline will be released in the future.
