Scalable Detection of Fossil Palynomorphs in Multifocal Digital Microscopy Images

The paper presents the first scalable, end‑to‑end pipeline for automated detection of fossil palynomorphs in whole‑slide, multifocal digital microscopy images. It introduces efficient image decomposition and compression into 2‑D tiles, benchmarks modern object detection models (including RF‑DETR) achieving an AP@50 of 0.879, and provides algorithms for synthesizing detections across large‑scale images. The pipeline reduces analysis time from days of manual inspection to under one hour, enabling larger‑scale palynological studies.

Automated Palynological Analysis System: Integrating Deep Metric Learning, Detection and Classification in Bright Field Microscopy

The paper introduces an automated high‑throughput microscopy system for melissopalynology that combines H∞ robust mechanical control with deep learning pipelines. It uses U^2‑Net for salient object detection and a DINOv2 Vision Transformer trained via deep metric learning for pollen grain classification, augmented with Gradient‑Weighted Attention for interpretable texture annotations. The system reports a 95.8% classification recall and at least a six‑fold speedup over manual expert analysis.

AtlasPatch: Scalable Foundation Model-based Tissue Detection and Patch Extraction for Computational Pathology

AtlasPatch is a scalable, high‑throughput whole‑slide image preprocessing method that uses a foundation‑model‑based tissue detector operating at thumbnail resolution. By updating only 0.076% of the SAM2 model weights and leveraging a curated dataset of 30,000 thumbnail‑mask pairs, it generates accurate tissue masks and directly produces patch coordinates at the desired magnification, eliminating repeated patch‑level inference. The approach achieves 0.986 precision, is up to 16× faster than existing deep‑learning methods, and maintains downstream multiple‑instance learning performance across six slide‑level classification tasks.

AgriCountDINO: Parameter-Efficient Exemplar-Guided Counting and Localization in Agriculture

AgriCountDINO is a parameter‑efficient, exemplar‑guided framework that jointly counts and localizes plants and their organs by conditioning frozen multiscale DINOv3 features on exemplar appearance and size, then decoding them into target points. It introduces missed‑object recovery and exemplar‑adaptive point NMS to improve detection accuracy. With only 8.4 M trainable parameters, it achieves a three‑shot MAE of 11.92 on the TPC‑268 benchmark and a zero‑shot MAE of 14.25 on unseen generic object categories in FSC‑147, outperforming previous methods without target‑domain training.

Multi-Scale ViT Inference with Habitat-Fit Priors and kNN Retrieval for Multi-Species Plant Identification

arXiv:2607. 14509v1 Announce Type: cross Abstract: This paper describes DS@GT ARC's third-place solution to the PlantCLEF 2026 challenge on multi-species plant identification in vegetation quadrat images, where systems must predict every species present in high-resolution (~3000 x 3000 pixel) plot photographs while training only on single-label images of individual plants.
