Grounding Image Composition with Label-Conditioned Visual Evidence

Read the original on arXiv Computer Vision →

Grounding Image Composition with Label-Conditioned Visual Evidence introduces the KU-PCPE benchmark, which provides image-level composition labels and class-specific geometric elements but lacks explicit visual evidence for each label. The dataset contains 4,093 training masks and a 1,327-task expert test split, with annotations that include segment-versus-line ratings to indicate whether region or semantic-guideline evidence better explains a label. Performance metrics show a gap between expert agreement (.867 Dice) and model predictions (.664 for the strongest deployable model, .672 for a proposal oracle, and .395 for a VLM proposal selector).

Contrastive Mask Fidelity: Reference-Free Auditing of Ground-Truth Masks in Remote Sensing Semantic Segmentation

arXiv:2608. 09101v1 Announce Type: cross Abstract: Semantic segmentation models are trained and evaluated against human-drawn masks, yet remote-sensing annotations are often coarse, incomplete, or misaligned; high overlap scores may then reflect agreement with imperfect labels rather than faithfulness to the image, creating an evaluation paradox.

VisionQ: VLM-as-a-Judge Taxonomy, Dataset and Benchmark for Qualitative Analysis in Computer Vision

VisionQ is a new benchmark for qualitative analysis in computer vision that evaluates vision‑language models (VLMs) on criterion‑conditioned visual discrimination. It is built from over 1,800 peer‑reviewed comparison figures in CVPR and ICCV papers, linking each image crop to author‑stated visual claims through 3,911 hand‑annotated data points. The benchmark includes a 51‑leaf taxonomy of visual criteria, a protocol that hides method identities and reports accuracy per criterion, and a DPO‑tuned Gemma‑4‑E4B judge that improves accuracy on a held‑out test set.

AgroGround: Multi-Granularity Grounded Recognition in Agriculture

AgroGround is a large‑scale dataset that links plant disease and agricultural target labels to image regions, enabling models to both recognize and localize these targets. It was created by automatically converting eight agricultural VQA datasets into 794,850 grounded instruction examples, including healthy images for negative supervision. Fine‑tuning a shared vision‑language model on these instructions improves recognition, joint accuracy, and healthy‑image abstention, outperforming its annotation teacher on both the AgroGround benchmark and the external PlantSeg test set.
