We describe a method that allows imaging of objects moving within heavily scattering random media. This should prove valuable in biological imaging and other applications.
Our proposed glasses-free tabletop 3D display, fvision, employs a hollow conical screen and tiny, circularly arranged projectors installed underneath the table. It floats interactive virtual 3D objects on a flat tabletop surface.
We propose a novel algorithm for stitching multiple synchronized video streams into a single panoramic video with spatial-temporal content-preserving warping. Compared to image stitching, video stitching faces several new challenges including temporal coherence, dominate foreground objects moving across views, and camera jittering. To overcome these issues, the proposed algorithm draws upon ideas...
Technological developments and the emergence of new equipment such smartphones have changed news paradigms. One of the most obvious consequences was the democratization of information with the so-called citizen journalism. Anonymous persons who through their mobile and social networks can report what is happening in seconds and with just one click in their mobile phone. But after this step, we are...
The focus of our research is on improving mobile image and video browsing interfaces. To get a better idea about real world mobile photo and video scenarios and to base our research on real world numbers we performed a survey of photo and video usage on smartphones and tablets. In an online survey we asked 215 participants of the German speaking region about their mobile image collections, their usage...
Tables are widely used for various activities. We can share and exchange such media as documents or photos on their surfaces. fVisiOn, our proposed novel glasses-free tabletop 3D display, is designed to be a communication tool to augment ordinary tabletop activities by naturally providing virtual 3D media alongside actual media. This paper introduces the basic idea of our proposed method and recent...
Three-dimensional (3D) measurement is an important means for robots to acquire information about their environment. Structure from Motion is one of these 3D measurement methods. The 3D reconstruction of objects in the environment can be obtained from pictures captured with single camera in Structure from Motion. Furthermore, the camera motion can be obtained simultaneously. Because of its simplicity,...
Our main goal was to design and implement a software and hardware infrastructure enabling us to run multiple interactive applications on our facade using different types of devices for interaction. This paper presents a modular software architecture to interact with media facades. Furthermore the paper will explain the hardware infrastructure of the facade. After that the modular software architecture...
Opinion mining deals with the determination of people's sentiments over the social web as positive, negative or neutral. Microblogs such as twitter serves as a rich source for opinion mining and sentiment analysis as opinions are shared by millions of users. In our paper, we have analyzed the various methods available through which the twitter data can be extracted. We have provided an overall picture...
This paper presents an immersive telepresence system for entertainment and meetings (ITEM). The system aims to provide a radically new video communication experience by seamlessly merging participants into the same virtual space to allow a natural interaction among them and shared collaborative contents. With the goal to make a scalable, flexible system for various business solutions as well as easily...
The last decade has witnessed an explosive growth in multimedia big data, with the invention of big data analytics technologies, such as Hadoop, Spark, Storm. All these technologies are valuable to mine intelligence from multimedia big data, and further shed new insights into multimedia networks. This paper presents an outlook on the development of future multimedia networks and discuss utilizing...
This paper proposes a smart, easy-deployed remote monitor system based on Android system. Different from normal monitor system, what you need to deploy the monitor system are only a camera, a PC with Linux system and an Android smart phone, which is commonly held by people. The system is based on the open-source library live555, FFmpeg and x264, thus it is readily extendable. In this system, the video...
We introduce our initial design of gesture interface for the TV control of visually impaired users, with its implementation and user study. Two bare-hand gesture sets were designed using simple linear and circular motions of arms. For the two gesture sets, a rule-based recognition system was developed using a Kinect sensor. In a user study, the linear and circular gesture sets on our recognition system...
Optical tomography provides visual images of the interior of objects. There are various methods depending on how the material behaves under scattering. If scattering is weak, one approach extracts the scattering amplitudes from the inputed projected images and estimates a cross-sectional image from images without scattering. Conversely, if the scattering is strong, an approach is to use the scattering...
In this paper, a vestibular rehabilitation system is proposed, which provides for realistic experiences based on multiple sensory media. Postures of vestibular rehabilitation exercises are taken by multiple cameras for multiple A/V media and their reference motion data are generated for similarity analysis. Watching the multiple media contents on multiple display devices and taking postures according...
Presentation of a prototype platform for accessing Venetian archives online and interactively (case study: Le Corbusier's unrealised project for a new Venice hospital). Specifically, commissioned by the Direzione Generale per gli Archivi (DGA), MeLa Media Lab has created an interactive and flexible online exhibition space which conforms to internet standards and enables a dynamic visualization of...
This paper looks at performance in the context of activism and digital video documentation in which performers' corporeality and the scenic space are mediated through video and online video sharing platforms such as YouTube. It aims to define the ways digital video materializes the body of the performer in front of the camera and how this corporeality is translated to the spectator. Despite all technical...
In this paper the issue of on-line adaptation of the robot vision system to variations in the refractive index of the ambient fluid is being considered. This is achieved by developing an analytical model of the light propagation through the AUV water-dome-air interface before entering the camera optics. The model developed is used for simulation of the AUV's camera dome. The effect of variations in...
As a trend, our everyday goods are changing to program-controlled ones from pure mechanical or electrical ones. The concept of ‘coded object’ was proposed for such a new generation product by Kitchin and Dooge. We propose a novel interaction method using OCR for coded objects, which is aimed at simplifying the operations on the configuration of coded objects and making the recording, sharing, and...
We previously proposed the artificial fiber (AF) patterns in order to be able to hide information in printed documents. AF pattern uses the features of the medium (e.g., paper). It has features of rotational invariance, low visibility of the hidden information. But it still suffered extraction threshold instability when using a camera to extract the information. This problem has now been overcome...
