Previous neural radiance fields often struggle to preserve high-frequency textures in urban and aerial large-scale scenes due to insufficient model capacity on the scene surface. This is attributed to their sampling locations or grid vertices falling in ...

Liver segmentation is considered as a challenge task, and accurate and reliable segmentation of liver is essential of the follow-up of liver treatment. In this paper, a novel liver segmentation method including intensity separation, region growing and ...

Aiming at the influence of the complex electromagnetic environment to radar, a method of visualization for radar electromagnetic waves under the influence of electronic jamming is presented. Firstly, presenting the flow of visualization for radar ...

Kyoto Visualization System (KVS) is a multi-platform, open-source C++ Toolkit for developing scientific visualization applications. KVS provides useful classes to quickly implement surface rendering, volume rendering, point-based rendering, and others. ...

Implicit surfaces (IS) are commonly used in image creation, modeling environments, modeling objects, and scientific data visualization. In this article, we present a survey of different techniques for fast visualization of IS. The main classes of ...

Recent advances in graphics hardware have made it a desirable goal to implement the Reyes algorithm on current graphics cards. One key component in this algorithm is the bound-and-split phase, where surface patches are recursively split until they are ...

Medical image three-dimensional reconstruction, which is of great value in medical research and clinical diagnosis, has been a focal field in recent years. How to achieve medical image three-dimensional reconstruction quickly and efficiently is a ...

This paper presents models and algorithms for estimating the shape of a mirrored surface from a single image of that surface, rendered under an unknown, natural illumination. While the unconstrained nature of this problem seems to make shape recovery ...

Based on the summary and analysis of work done in the field of surface rendering, this paper proposes a mathematical method which can significantly improve the precision of surface rendering. The method is built on the rational function interpolation ...

In the year 2007 we celebrate the 20-th anniversary of coining the notion of volume rendering, followed by its first "official" usage in the papers by Levoy and by Drebin, Carpenter and Hanrahan in 1988. The new and revolutionary introduced by these ...

We present a side-by-side analysis of two recent image space approaches for the visualization of vector fields on surfaces. The two methods, Image Space Advection (ISA) and Image-Based Flow Visualization for Curved Surfaces (IBFVS) generate dense ...

A new method for the synthesis of dense, vector-field aligned textures on curved surfaces is presented, called IBFVS. The method is based on Image Based Flow Visualization (IBFV). In IBFV two-dimensional animated textures are produced by defining each ...

Automatic detection of meaningful isosurfaces is important for producing informative visualizations of volume data, especially when no information about the data origin and imaging protocol is available. We propose a computationally efficient method for ...

The display of iso-surfaces in medical data sets is an important visualizationtechnique used by radiologists for the diagnosis of volumetricdensity data sets. The demands put by radiologists on sucha display technique are interactivity, multiple stacked ...

This paper presents an approach for surface rendering in 3D rectilinear datafield. The approach will first detect the border of the given object in the field by underlying function fitting and the second gradient derivative calculating. On marking ...

In this article we present the visualization of the human body basing upon the X-ray CT and MR images. Topics and examaples of images rendered by the computer are all selected from the studies in the authors' laboratory during about twenty years. Topics ...

Three methods for evaluating the surface coordinates, first derivatives, and normal vectors of a NURB surface are compared. These methods include forward differencing, knot insertion, and a tow-stage Cox-de Boor technique. The computational complexity of ...
