TasselNetV4: A vision foundation model for cross-scene, cross-scale, and cross-species plant counting

arXiv.org Artificial Intelligence

Accurate plant counting provides valuable information for agriculture such as crop yield prediction, plant density assessment, and phenotype quantification. Vision-based approaches are currently the mainstream solution. Prior art typically uses a detection or a regression model to count a specific plant. However, plants have biodiversity, and new cultivars are increasingly bred each year. It is almost impossible to exhaust and build all species-dependent counting models. Inspired by class-agnostic counting (CAC) in computer vision, we argue that it is time to rethink the problem formulation of plant counting, from what plants to count to how to count plants. In contrast to most daily objects with spatial and temporal invariance, plants are dynamic, changing with time and space. Their non-rigid structure often leads to worse performance than counting rigid instances like heads and cars such that current CAC and open-world detection models are suboptimal to count plants. In this work, we inherit the vein of the TasselNet plant counting model and introduce a new extension, TasselNetV4, shifting from species-specific counting to cross-species counting. TasselNetV4 marries the local counting idea of TasselNet with the extract-and-match paradigm in CAC. It builds upon a plain vision transformer and incorporates novel multi-branch box-aware local counters used to enhance cross-scale robustness. Two challenging datasets, PAC-105 and PAC-Somalia, are harvested. Extensive experiments against state-of-the-art CAC models show that TasselNetV4 achieves not only superior counting performance but also high efficiency.Our results indicate that TasselNetV4 emerges to be a vision foundation model for cross-scene, cross-scale, and cross-species plant counting.


Speech Language Models for Under-Represented Languages: Insights from Wolof

arXiv.org Artificial Intelligence

We present our journey in training a speech language model for Wolof, an underrepresented language spoken in West Africa, and share key insights. We first emphasize the importance of collecting large-scale, spontaneous, high-quality unsupervised speech data, and show that continued pretraining HuBERT on this dataset outperforms both the base model and African-centric models on ASR. We then integrate this speech encoder into a Wolof LLM to train the first Speech LLM for this language, extending its capabilities to tasks such as speech translation. Furthermore, we explore training the Speech LLM to perform multi-step Chain-of-Thought before transcribing or translating. Our results show that the Speech LLM not only improves speech recognition but also performs well in speech translation. The models and the code will be openly shared.


Nuclear Diffusion Models for Low-Rank Background Suppression in Videos

arXiv.org Artificial Intelligence

ABSTRACT Video sequences often contain structured noise and background artifacts that obscure dynamic content, posing challenges for accurate analysis and restoration. Robust principal component methods address this by decomposing data into low-rank and sparse components. Still, the sparsity assumption often fails to capture the rich variability present in real video data. To overcome this limitation, a hybrid framework that integrates low-rank temporal modeling with diffusion posterior sampling is proposed. The proposed method, Nuclear Diffusion, is evaluated on a real-world medical imaging problem, namely cardiac ultrasound dehazing, and demonstrates improved dehazing performance compared to traditional RPCA concerning contrast enhancement (gCNR) and signal preservation (KS statistic).


Israeli strike on Yemen's Houthis reportedly kills eight

BBC News

Israeli strike on Yemen's Houthis reportedly kills eight The Israeli military says its air force has carried out its most powerful strike in Yemen in response to the Houthi movement's repeated drone and missile attacks on Israel. The Israel Defense Forces (IDF) said dozens of its aircraft bombed targets belonging to the Houthis' security and intelligence services, and military in the capital Sanaa. The Houthi-run government's health ministry denounced what it called Israel's brutal crime, saying civilian facilities and residential buildings were hit and that eight people were killed. It comes a day after 22 people were injured, two of them seriously, in a Houthi drone attack in the Israeli Red Sea resort of Eilat. The Houthis have controlled much of north-western Yemen since they ousted the country's internationally recognised government from there 10 years ago, sparking a civil war.

Why have Spain and Italy sent ships to assist the Gaza Sumud flotilla?

Al Jazeera

Can Israel survive economic isolation? Why have Spain and Italy sent ships to assist the Gaza Sumud flotilla? Italy and Spain have decided this week to dispatch naval vessels to assist the Global Sumud Flotilla on its way to break Israel's siege of Gaza. The unprecedented move to support a flotilla headed towards the Palestinian enclave comes after repeated attacks against the Sumud Flotilla, including a drone attack early on Wednesday. Israel is widely believed to be behind the attacks.


Amid drone attacks, activists confront fear and hope on Gaza flotilla

Al Jazeera

Can Israel survive economic isolation? The activists of the Global Sumud Flotilla remain alert. Wednesday's drone attack on the vessels - heading towards Gaza to break Israel's siege on the Palestinian enclave - is not expected to be the last. As the flotilla, currently travelling in Greek territorial waters, nears Gaza, a larger Israeli attack is expected. Acar is experienced in spotting drones and assessing security risks, having previous experience trying to reach Gaza on June's Madleen flotilla, which Israel intercepted.


Drone attacks leave Denmark exposed - and searching for response

BBC News

A night of drone incidents at airports and military bases all over Jutland, western Denmark, has not caused any harm or damage - and yet it has exposed the country's defences as vulnerable to attack. In an era of hybrid warfare, there is a sense of embarrassment in Denmark - a founding member of the North Atlantic Treaty Organization (Nato) alliance - that its critical infrastructure has become so vulnerable. Aalborg and Billund airports had to close, while drones were spotted at Esbjerg, Sonderborg and Skrydstrup. Aalborg also serves as a military base and Skrydstrup is home to some of the air force's F-35 and F-16 war planes. Drones were also seen over the Jutland Dragoon regiment at Holstebro .
