Abstract Poisson disk distributions have many applications in the field of computer graphics. Besides sampling, Poisson disk distributions are used in object distribution, non-photorealistic rendering and procedural texturing. Over the years, a large number of methods for generating Poisson disk distributions have been proposed, making it difficult to choose the right method for a given applica...

Two multiprocessor system-on-chip (MPSoC) architectures are proposed and compared in the paper with reference to audio and video processing applications. One architecture exploits a homogeneous topology; it consists of 8 identical tiles, each made of a 32bit RISC core enhanced by a 64-bit DSP coprocessor with local memory. The other MPSoC architecture exploits a heterogeneoustile topology with ...

In this study, we examined the sensitivity of embossed pattern depth to preheat supply and cooling, and also tested how pattern type and density affect the embossed depth. The main factors such as roller temperature, roller speed, and applied force that mostly affect embossed pattern qualities of roll-to-roll hot embossing were determined based on the response surface methodology. Eight conditi...

We show how one-dimensional cellular automata can be dynamically simulated by DNAbased tiles within the Active Abstract Tile Assembly Model (Active aTAM). The Active aTAM is a tile model for self assembly where tiles are able to transfer signals and change identities according to the signals received. We give a brief description of the model with the dynamics of tile attachment and signal passi...

VideoPlay is a novel tabletop system for editing video using tangible objects and multi-touch interaction. It targets the unique capabilities of the Microsoft Surface platform which supports high precision multi-touch and physical object sensing and tracking. New interaction techniques are presented that allow content to be downloaded from mobile devices onto the table. Physical tiles represent...

The article is devoted to the introduction into scientific circulation of a collection terracotta architectural details from excavations Upper City Olbia in second half 1920-ies. Archaeological research was conducted by Scientific Council All-Ukrainian Academy Sciences according plan proposed B. V. Farmakovskyi after resumption 1924. Two details, fragments polychrome simas Late Archaic period, ...

In this paper, a metadata-based quality-estimation model is proposed for tile-based omnidirectional video streaming services, aiming to realize quality monitoring during service provision. the (ODV) ODV divided into tiles, and high-quality tiles low-quality are distributed in accordance with user's viewing direction. When user changes direction, temporarily watches tiles. addition, longer time ...

This paper presents an overview of our recent work on managing image and video data. The first half of the paper describes a representation for the semantic spatial layout of video frames. In particular, Markov random fields are used to characterize the spatial arrangement of frame tiles that are labeled using support vector machine classifiers. The representation is shown to support similarity...

Oscar Gilbert , Jacob Hendricks , Matthew J. Patitz ? ? , and Trent A. Rogers † Abstract. In this paper we investigate the computational power of the polygonal tile assembly model (polygonal TAM) at temperature 1, i.e. in non-cooperative systems. The polygonal TAM is an extension of Winfree’s abstract tile assembly model (aTAM) which not only allows for square tiles (as in the aTAM) but also al...
