Research on seamless image stitching based on fast marching method

open access: yesIET Image Processing, 2023
Image stitching is an important way to achieve large‐field high‐resolution imaging. The inconsistencies in brightness and structure and defects in ghosting, blurring and misalignment between images, which are inevitable and difficult to eliminate, make a

Marching Cubes and Histogram Pyramids for 3D Medical Visualization

open access: yesJournal of Imaging, 2020
This paper aims to implement histogram pyramids with marching cubes method for 3D medical volumetric rendering. The histogram pyramids are used for feature extraction by segmenting the image into the hierarchical order like the pyramid shape.

Fast convergence layout algorithm for drawing graphs in marching-graph [PDF]

open access: yes, 2008
Marching-Graph is a new visualization that integrates the graph metaphor and the spatial metaphor into a single visualization. It provides users with highly interactive maps for accessing the logical structures of information that has the geographical ...

A Modified Fast Marching Method [PDF]

open access: yes, 2003
In most, if not all fast marching methods published hitherto, the input cost function and the output arrival time are sampled on exactly the same grid. But since the input data samples are differences of the output samples we found it natural to separate the input and output grid half a sampling unit in all coordinates (two or three).We also employ 8 ...

Fast Marching Techniques for Teaming UAV’s Applications in Complex Terrain

open access: yesDrones, 2023
In this paper, we present a study on coverage missions carried out by UAV formations in 3D environments. These missions are designed to be applied in tracking and search and rescue missions, especially in the case of accidents.

Fast Marching Method for Generic Shape from Shading [PDF]

open access: green, 2005
We develop a fast numerical method to approximate the solutions of a wide class of equations associated to the Shape From Shading problem. Our method, which is based on the control theory and the interfaces propagation, is an extension of the “Fast Marching Method” (FMM) [30,25].

Can local single-pass methods solve any stationary Hamilton-Jacobi-Bellman equation? [PDF]

open access: yes, 2013
The use of local single-pass methods (like, e.g., the Fast Marching method) has become popular in the solution of some Hamilton-Jacobi equations. The prototype of these equations is the eikonal equation, for which the methods can be applied saving CPU ...

A Comparison of Local Path Planning Techniques of Autonomous Surface Vehicles for Monitoring Applications: The Ypacarai Lake Case-study

open access: yesSensors, 2020
Local path planning is important in the development of autonomous vehicles since it allows a vehicle to adapt their movements to dynamic environments, for instance, when obstacles are detected.
