A new way of Rich Image Representation (VectorPixels)
Simons, Alain; Prakash, Edmond; Wood, James
2014 - anglický
For decades the same technologies has been used for generating images on computer systems. On the one hand
you have bitmap and on the other hand vector technology. Bitmap or pixel technology is mostly used for the
representation of rich colour images. The other available imaging technology, vectors, is mainly used to present
logos and drawings without photo realistic details.
But both techniques have their disadvantages and advantages. In recent years a lot of research has been done to
combine the advantages of both techniques in a comprehensive solution. Much research focused on giving a
vector illustration a realistic picture look.
There was no development from scratch and that is exactly what this paper wants to propose, an algorithm to
invent the pixel again. By always applying new developments on existing technologies generating images
became a mix of various techniques and a rather complex matter.
With the use of VectorPixels (VP) the concept of a pixel will be redefined. In contrast with a pixel (Picture
Element) a VectorPixel will be defined by a mathematical description and be resolution independent.

Connect-S: A Physical Visualization Through Tangible Interaction
Giang, Ken; Funk, Mathias
2014 - anglický
In our current society, open data streams are more and more available through the Internet. This data can have an
increasing impact on everyday life. Its full potential can, however, only reached through better integration and
new interfaces. The goal of this project is to explore the possibilities of repurposing public information in a
developing area of a large city in the Netherlands. Can we create a tangible interaction with use of physical
visualization of these data streams? A series of prototypes have been made to develop a physical visualization
through the method of research through design. Users were involved in expert panels and interviews to fine-tune
and create a final prototype, Connect-S. The concept shows the opportunities of using physical visualization in
connection with physical interaction for browsing and navigation.

Adaptive Projection Displays: a low cost system for public interactivity
Dundas, Jenna; Wagner, Michael
2014 - anglický
Interactive digital public displays that track viewer’s position are currently inaccessible to the average consumer.
Many tracking systems available on the market are prohibitively expensive and are out of scope for small business
owners to purchase. A system can be devised by researching and testing various consumer level tracking technologies
in a low cost and accessible manner. Microsoft’s Kinect in tandem with Unity3D offers a system that is
straightforward to use and allows for ease of implementation. The resulting technique can be quickly carried out
to create an interactive digital public display.

Lane Marking Detection in Various Lighting Conditions using Robust Feature Extraction
Jang, Ho-Jin; Baek, Seung-Hae; Park, Soon-Yong
2014 - anglický
Robustly extracting the features of lane markings under different lighting and weather conditions such as
shadows, glows, sunset and night is the a key technology of the lane departure warning system (LDWS). In this
paper, we propose a robust lane marking feature extraction method. By useing the characteristics of the lane
marking to detect candidate areas. The final lane marking features are extracted by first finding the center points
of the lane marking in the candidate area then these center point pixels are labeled according to the intensity
similarity along the direction of the vanishing point. The performance of the proposed method is evaluated by
experiment at results using real world lane data.

Survey on Automated LEGO Assembly Construction
Kim, Jae Woo; Kang, Kyung Kyu; Lee, Ji Hyoung
2014 - anglický
LEGO has been very popular toy in the world because it is attractive and fun to play with and stimulates one's
creativity by providing means to conveniently assemble a variety of interesting shapes using the limited types of
given bricks. However, it is hard for the beginners to design and assemble complex models they desire to make
without instructions. Building a LEGO assembly manually usually requires a significant amount of trial-anderror.
LEGO company therefore presented the LEGO construction problem in 1998 and in 2001. The problem
statement is "Given any 3D body, how can it be built from LEGO bricks?" In this paper we will investigate the
current research efforts to address the LEGO construction problem. We will review the problem definition,
formulation, and a variety of approaches to solve the problem. We will discuss the data representations for input
3D polygonal models and the LEGO assembly structures, cost functions that will guide the search for the
optimal solution, and various solution methods.
