The 1$^{\text{st}}$ Workshop on Maritime Computer Vision (MaCVi) 2023 focused on maritime computer vision for Unmanned Aerial Vehicles (UAV) and Unmanned Surface Vehicle (USV), and organized several subchallenges in this domain: (i) UAV-based Maritime Object Detection, (ii) UAV-based Maritime Object Tracking, (iii) USV-based Maritime Obstacle Segme...
Preprint
The control problem of a multi-copter swarm, mechanically coupled through a modular lattice structure of connecting rods, is considered in this article. The system's structural elasticity is considered in deriving the system's dynamics. The devised controller is robust against the induced flexibilities, while an inherent adaptation scheme allows fo...

In this work, we explore the process of designing a long-term drone surveillance system by fusing object detection, tracking and classification methods. Given a video stream from an RGB-camera, a detection module based on YOLOV5 is trained for finding drones within its field of view. Although in drone detection, high accuracy and robustness is achi...
Chapter
This paper reports the results of the 5th edition of the “Drone-vs-Bird” detection challenge, organized within the 21st International Conference on Image Analysis and Processing (ICIAP). By taking as input video samples recorded by common cameras, the aim of the challenge is to devise advanced approaches aimed at spotlighting the presence of drones...
Article
Visual object tracking methods depend upon deep networks that can hardly meet real-time processing requirements on mobile platforms with limited computing resources. In this work, we propose a real-time object tracking framework by enhancing a lightweight feature pyramid network with Transformer architecture to construct a robust target-specific ap...
Article
Full-text available
UAVs operating in a leader-follower formation demand the knowledge of the relative pose between the collaborating members. This necessitates the RF-communication of this information which increases the communication latency and can easily result in lost data packets. In this work, rather than relying on this autopilot data exchange, a visual scheme...

Recent object tracking methods depend upon deep networks or convoluted architectures. Most of those trackers can hardly meet real-time processing requirements on mobile platforms with limited computing resources. In this work, we introduce the Siamese Transformer Pyramid Network (SiamTPN), which inherits the advantages from both CNN and Transformer...
Article
Full-text available
This work is devoted to the presentation of a Wireless Sensor System implementation for upper limb rehabilitation to function as a complementary system for a patient’s progress supervision during rehabilitation exercises. A cost effective motion capture sensor node composed by a 9 Degrees-of-Freedom (DoF) Inertial Measurement Unit (IMU) is mounted...
Chapter
Full-text available
The scope of this chapter is the development of an aerial manipulator platform using an octarotor drone with an attached manipulator. An on-board spherical camera provides visual information for the drone’s surroundings, while a Pan-Tilt-Zoom camera system is used to track targets. A powerful computer with a GPU offers significant on-board computat...
Article
In this article, a novel robotic platform for robotic assisted minimally invasive surgical operations is presented. The platform consists of a 3 Degree-of-Freedom (DoF) passive tool holder and a 12 DoF robotic probe for dexterous motion upon insertion. The developed prototype is presented in terms of its mechatronic and kinematic structure. Regardi...
Conference Paper
The design, implementation and experimental evaluation of a minimally invasive surgical robotic instrument is presented in this article. The tool is constructed using rapid prototyping techniques and each degree-of-freedom is actuated via an antagonistic tendon driven mechanism using servo motors. The accompanying software runs under the Robot Oper...
Conference Paper
The design, fabrication and testing of an SMA-actuated redundant robotic-probe for minimally invasive surgical procedures is the subject of this article. The resulting probe is lightweight, modular and its controller relies on an antagonistic principle for each pair of tendons. The developed platform consists of a twelve Degree of Freedom snake-lik...
Conference Paper
This article is concerned with the design, implementation and control of a redundant robotic tool for Minimal Invasive Surgical (MIS) operations. The robotic tool is modular, comprised of identical stages of dual rotational Degrees of Freedom (DoF). An antagonistic tendon-driven mechanism using two DC-motors in a puller-follower configuration is us...
Conference Paper
In this paper the design and positioning efficiency tests of a robotic endoscope prototype for Minimally Invasive Surgical (MIS) operations are presented. The manufactured probe features twelve Degrees-of-Freedom (DoF), using universal joints and links in a redundant configuration. For actuation, Shape Memory Alloys (SMAs) are used in a smart confi...
Conference Paper
A fuzzy rule-based and energy-efficient method for estimating the free size of parking places in smart cities is proposed. In particular, the estimation is the output value of a fuzzy inference system (FIS) which was implemented on each wireless sensor mote (WSM) of a wireless sensor network (WSN) placed in the ground below the parking places and i...
Conference Paper
The development and experimental evaluation of a prototype endoscopic robotic surgical tool is presented in this article. Smart memory alloys (SMA) are used as wires in a tendon-driven actuation mechanism. The 2N-DOF redundant manipulator is a cascade configuration of N-universal joint modules. The kinematics of the tool is analysed and simple yet...
