In this paper we present a scalable multi-view video streaming system with client-side view interpolation. Most parts of the system have been shown to be able to perform in real-time, but never as a complete system. Even though our algorithms are not yet highly optimized, we show that running a complete multi-view streaming system video on consumer hardware is possible today. Since multi-view coding...
Intraoperative thermographic imaging, associated with time-resolved data analysis, is used to identify and visualise functional areas and pathological tissue in brain surgery. In this contribution we propose a hardware-software system for real-time pre-processing, fusion, and analysis of concurrent infrared and whitelight recordings. As a proof-of-concept, a digital temporal filter is applied to the...
Wireless Multimedia Sensor Networks (WMSN) are one of the emerging paradigms of the Internet of Things (IoT) that are used to retrieve content including scalar data, video and audio streams and still images from the physical environment. In contrast to scalar sensor (such as temperature and humidity sensor) nodes, multimedia sensor nodes capture high volumes of data and perform far more complex tasks...
Recent advances in technology and rapid growth of consumer electronics have made tremendous amount of multimedia information available to the general population. Browsing through large collections of consumer videos and manually creating summaries can be tedious. Automatic summarization techniques will give the user an easy way to look up important content of a collection of media and to browse media...
A FPGA-based embedded system development platform with dual-camera support, named MorFPGA Duo, is presented in this paper. The MorFPGA Duo platform adopts the modular design concept and is capable of a dual core employing the ARM Cortex A9, two channel SDI cameras with Full-HD resolution, versatile built-in peripherals and high expandability to satisfy users' eager needs for state-of-the-art research...
In previous work it has been shown that volume registration can be used to generate dense 3D maps from RGBD video data with various advantages over feature matching approaches. This paper presents preliminary work in applying this technique to general monocular video data. This approach does not require additional RGB-D hardware and generates dense 3D models with similar complexity.

We present an efficient open-source implementation of a novel video alignment algorithm, based on low dimensionality frame matching and the recently introduced ECC image registration algorithm.
This paper describes a voice navigational system for the visually impaired which runs on the user's smart-phone as an application and requires no additional expensive or heavy hardware. This system requires just the live video stream from the user's phone camera and an internet connection, and hence can be used on the most basic of smart-phones. The system proposed here identifies obstacles in front...
We are presenting PanoVC — a mobile telepresence system based on continuously updated panoramic images. We are showing that the experience of telepresence, i.e. the sense of "being there together" at a distant location can be achieved with standard state-of-the-art mobile phones. Because mobile phones are always on hand users can share their environments with others in a pervasive way. Our...
A hardware and software solution for guitar string vibration measurement by fast cameras is described. Orthogonal setup for 3D image acquisition is proposed capable to capture several thousand image frames per second. Dedicated image processing algorithm was developed and described in the paper, aimed at tracking the movement of some selected points along the string. Fast and accurate tracking results...
Live results obtained from the first real-time high-resolution free viewpoint synthesis hardware that utilizes three-camera disparity estimation are presented. The proposed hardware generates high-quality free viewpoint video at 55 frames per second on a Virtex-7 FPGA at a 1024×768 XGA video resolution for any horizontally-aligned arbitrary camera positioned between the leftmost and rightmost physical...
The recent development of high-quality free viewpoint synthesis algorithms and their implementations allows to realize glasses-free 3D perception. Although many algorithms have been developed in this domain, the real-time hardware realization of a free viewpoint synthesis for real-world images is challenging due to its high computational load and memory bandwidth requirements. In this paper, the first...

Smartphones are frequently used to shoot and share videos online and emerging applications, such as Augmented Reality, will increase the usage of the camera. Unfortunately, shooting and streaming video drains a modern smartphone's battery very quickly. We report results from a measurement study to dissect the smartphone energy consumption when using such an application. Our main findings are that...
