Iteracinis optimizavimu pagrįsto akies dugno kraujagyslių trasavimo metodo variantas

Informacijos Mokslai, 2009
Akies dugne matomos smulkios žmogaus kraujagyslės. Iš jų pakitimų galima diagnozuoti įvairias sisteminių ligų komplikacijas. Dėl to daug dėmesio skiriama automatiniams kraujagyslių stebėjimo akies dugno vaizduose algoritmams.

Application of a New Shore-Based Vessel Traffic Monitoring System Within San Francisco Bay

Frontiers in Marine Science, 2020
Vessel traffic management systems can be employed for environmental management where vessel activity may be of concern. One such location is in San Francisco Bay where a variety of vessel types transit a highly developed urban estuary. We analyzed vessel

Plot Quality Aided Plot-to-Track Association in Dense Clutter for Compact High-Frequency Surface Wave Radar

Remote Sensing, 2022
Due to high false alarm rate and low positioning accuracy of compact high-frequency surface wave radar in moving vessel detection, false plot-to-track association often occurs during moving vessel tracking, thus leading to track fragmentation and false ...

Advances in procedural techniques--antegrade. [PDF]

, 2014
There have been many technological advances in antegrade CTO PCI, but perhaps most importantly has been the evolution of the "hybrid' approach where ideally there exists a seamless interplay of antegrade wiring, antegrade dissection re-entry and ...

Robust MPC-Based Fault-Tolerant Control for Trajectory Tracking of Surface Vessel

IEEE Access, 2018
A robust control method, based on a model predictive control, is developed for the trajectory tracking of a surface vessel with sensor failures. The kinematic model of a surface vessel is first obtained.

Vessel tractography using an intensity based tensor model with branch detection [PDF]

, 2013
In this paper, we present a tubular structure seg- mentation method that utilizes a second order tensor constructed from directional intensity measurements, which is inspired from diffusion tensor image (DTI) modeling.
