In the field of agent-based modeling (ABM), visualizations play a key role in conveying, identifying and understanding the relevant behaviors of a model. However, few toolkits provide modelers graphic tools and visual cues for the design of efficient and communicative visualizations. In this paper, we review some technologies in the NetLogo ABM toolkit that improves its design of model visualiz...

Information graphics (non-pictorial graphics such as bar charts and line graphs) contain a great deal of knowledge. Information retrieval research has focused on retrieving textual documents and on extracting images based on words appearing in the accompanying article or based on low-level features such as color or texture. Our goal is to build a system for retrieving information graphics that ...

This paper presents a new face recognition method using virtual view-based eigenspace. This method provides a possible way to recognize human face of different views even when samples of a view are not available. To achieve this, we have developed a virtual human face generation technique that synthesizes human face of arbitrary views. By using a frontal and profile images of a specific subject...

Volumes acquired for medical purposes are continuously increasing in size, faster than graphic cards memory capacity. Large volumetric datasets do not fit into GPU memory and therefore direct rendering is not possible. Even large volumes that still fit into GPU memory make frame rates decay. In order to reduce the size of large volumetric models, we present a new compression scheme. In this pap...

The main characteristics of ignition and combustion fuel droplets (organic coal-water fuel, oil emulsion, in the usual state) placed on heated surfaces structural steel (DIN standard grade X16CrNi25-20) were experimentally determined under conditions corresponding to start-up nominal operation power-generating equipment. It was shown that due application texture surfaces, it is possible change ...

Texture analysis is key to better understanding of the relationships between microstructures materials and their properties, as well use models in process systems using raw signals or images input. Recently, new methods based on transfer learning with deep neural networks have become established highly competitive approaches classical texture analysis. In this study, three traditional approache...

We present a complete system for efficient 3D video object extraction, representation, coding, and interactive rendering. 3D video objects provide the same functionalities as virtual computer graphic objects but also depict motion and appearance of real world moving objects. They can be viewed interactively from any direction and can be integrated in complete 3D scenes together with other virtu...

This article tackles some important issues relating to the analysis of a particular case of complex ancient graphic images, called “lettrines”, “drop caps” or “ornamental letters”. Our contribution focuses on proposing generic solutions for lettrine recognition and classification. Firstly, we propose a bottom-up segmentation method, based on auto-correlation features, ensuring the separation of...

Diffusion curves are a powerful vector graphic representation that stores an image as a set of 2D Bezier curves with colors defined on either side. These colors are diffused over the image plane, resulting in smooth color regions as well as sharp boundaries. In this paper, we introduce a new automatic diffusion curve coloring algorithm. We start by defining a geometric heuristic for the maximum...
