PineSORT: A Simple Online Real-time Tracking Framework for Drone Videos in Agriculture

IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR) Workshops

PineSORT is a Multiple Object Tracking (MOT) system for drone-based agricultural monitoring. It improves tracking by adding motion direction cost, ORB-based camera motion compensation, a three-stage association strategy, and overlap management. It significantly enhances accuracy compared to BoTSORT and AgriSORT on pineapple drone datasets.

Simple Object Detection Framework without Training

2024 IEEE 6th International Conference on BioInspired Processing (BIP)

This paper introduces a simple object detection framework based on few-shot methods and Visual Foundation Models (VFM). The framework integrates object proposal, embedding creation, and classification. It is applied to pineapple localization in drone imagery, providing a scalable and cost-effective solution in data-scarce environments.

Artificial Intelligence in STEM Education: Interactive Hands-on Environment using Open Source Electronic Platforms

Tecnología en Marcha

This article describes a constructivist hands-on methodology to teach Artificial Intelligence using open-source electronic platforms such as Arduino, Raspberry Pi, and Snap Circuits. The approach emphasizes creativity, inclusion, and diversity while motivating students to develop innovative AI solutions for real-world problems.

Evaluation of the Influence of Multispectral Imaging for Object Detection in Pineapple Crops

2023 IEEE 5th International Conference on BioInspired Processing (BIP)

This research explores the use of multispectral drone images, combining RGB with near-infrared and red-edge channels, for object detection in pineapple crops. The study examines image alignment techniques (SIFT, ORB) and evaluates early and late fusion strategies for incorporating multispectral data into object detection pipelines.

The Women’s Antenna: An experience of community technology construction led by Cabécar women of Costa Rica

2023 IEEE International Humanitarian Technology Conference (IHTC)

This work documents the experiences of Cabécar women leaders in Costa Rica, highlighting their community-driven technology initiatives. The women created a local communication network inspired by cultural metaphors, bridging the digital divide while preserving ancestral wisdom and strengthening indigenous decision-making.

STEM education in semi-virtual interactive environment

Tecnología en Marcha

This paper proposes a semi-virtual learning model for STEM education during the Covid-19 pandemic. Volunteers provide synchronous guidance to students in interactive environments supported by workshops and virtual tools, ensuring continuity of STEM learning despite social restrictions.

ML4H Auditing: From Paper to Practice

Proceedings of the Machine Learning for Health NeurIPS Workshop (PMLR)

This work applies the ML4H audit framework proposed by the ITU/WHO Focus Group on Artificial Intelligence for Health (FG-AI4H) to three use cases: diabetic retinopathy, Alzheimer’s disease, and cytomorphologic classification for leukemia diagnostics. The study highlights the importance of bias, interpretability, and robustness assessments, bridging the gap between proposed guidelines and their application in real-world healthcare practice.

Quantum Computing

Quantum computing is the use of quantum-mechanical phenomena such as superposition and entanglement to perform computation. Computers that perform quantum computations are known as quantum computers.

• Quantum Teleportation
• Quantum Cryptography
