Selective Spatio-Temporal Fruit Inspector (S$^2$FI): A Mamba-based Framework for Rotational Fruit Quality Assessment

The paper introduces the Selective Spatio-Temporal Fruit Inspector (S$^2$FI), a low‑cost, high‑efficiency fruit sorting system that uses a 3D convolutional encoder and a Mamba‑based backbone to extract spatiotemporal features and adaptively weight informative frames during fruit rotation. The hardware design features a dual‑conveyor and curved rail system powered by household electricity, enabling fast deployment and lightweight embedded operation. Experiments on a newly built dataset of 6,460 samples demonstrate that S$^2$FI achieves the best balance of accuracy, speed, and practicality compared to baseline methods.

A Lightweight Multimodal Vision-Language Framework for Early-Stage Anatomical Green Fruit Classification in Commercial Orchards

The paper introduces a lightweight multimodal vision‑language framework based on TinyCLIP for fine‑grained classification of early‑stage apple fruitlet anatomy (calyx, fruitlet body, peduncle) in orchard images. Using a dataset of 600 high‑resolution RGB images, the model employs domain‑specific language prompts and a sliding‑window inference strategy to produce interpretable heatmaps for whole‑image localization. Achieving macro‑F1 of 0.93 on an NVIDIA T4 GPU and maintaining accuracy after INT8 quantization, the system is optimized for edge deployment on NVIDIA Jetson hardware with model sizes around 127‑137 MB and millisecond‑level inference.

RootDown: Deploying and Benchmarking Models for Beet-Root Detection on Edge Devices

RootDown presents an end‑to‑end image‑based pipeline for detecting partially occluded sugar beets on loader conveyors, a key step toward automated quality inspection. The authors introduce a dedicated benchmark and an automatic annotation strategy that uses the SAM 3 foundation model to generate bounding boxes, comparing these labels with manually annotated ones. They also evaluate deployment on edge hardware, showing that a Raspberry Pi 5 with a Hailo accelerator can perform high‑performance, low‑power inference suitable for mobile outdoor use.

RankGround: Efficient High-Resolution GUI Grounding via Lightweight Reranker-Guided Crop Selection

RankGround is a two‑stage framework for GUI grounding that uses a single Vision‑Language Model call per query. It introduces GroundRanker, a lightweight multimodal reranker that selects the most promising crop from a dense candidate set, trained with a two‑stage curriculum on ranking supervision data derived from existing grounding datasets. Experiments show RankGround outperforms strong baselines, achieving 1.4× faster inference and a 5.5% average improvement in localization accuracy over the second‑best method across all backbones and screen scales.
