Ubiquitous wireless local networks which use channel transfer function estimation to compensate for echoes on the wireless channel are uniquely suited for motion detection as a secondary use. In this way, added value can be provided without additional hardware. This paper presents a procedure with uses channel state information of an IEEE 802.11 High Throughput wireless link to reliably detect the...
This paper proposes a High Dynamic Range (HDR) system with low computation complexity based on inexpensive electronic devices. It utilizes advanced hardware structure with CMOS sensors that can generate multiple frames consisting of long and short exposures. In addition, the interval time between long and short frames can be set to a few msec or even less. Existing HDR recovering and compression techniques...
Array microphones are frequently used in the field of speech signal applications. In this paper a use case for array microphones combined with signal processing and IEEE 802.1 AVB Ethernet-based audio signal transmission is presented. The proposed application is intended for conferencing systems. The array microphones with beam steering and sound source localization algorithm are used to span multiple...
The typical result of an entire digital film production chain are multiple versions of a media file. This constitutes a great challenge in creating and managing for content creators. Especially in post production processes, different versions arise for final distribution of several resolutions, frame rates, languages and subtitles. The Interoperable Master Format (IMF) is a uniform master standard...
This paper demonstrates the application of electromyography (EMG) signals for controlling home devices. To achieve this we have used an armband called MYO® that has an array of eight sEMG sensors around the forearm. We have studied 15 different hand gestures to create a dictionary of gesture control. We have achieved gesture recognition using Support Vector Machines (SVMs) as a classification method...
This paper presents a robust hand detection algorithm using the facial information. The proposed algorithm consists of four steps: (i) detection of a face, (ii) generation of regions of interest (ROI) to detect hands, (iii) skin color extraction from the face region, and (iv) detection of hands using the face skin color in the ROI. The proposed algorithm can reduce false detection caused by a similar...
In 2015, NetFlix made the headlines with nearly 37% of Internet traffic being caused by their streaming applications1. The trend towards similar applications is further accelerated by increasing number of mobile devices used to consume high resolution video and interact with low latency. Hence, new challenges arise that can no longer be solved by solely altering the network's edge. Software-Defined...
The present paper describes a low-cost algorithm for video stabilization. Like other feature based algorithms, it is robust to motion blur, noise and illumination changes. Moreover, maintaining real time processing, it is not negatively affected by moving objects in the scene, works fine even in conditions of low details in the background and it is robust to scene changes.
This paper presents a visionary concept, Digital Senses that aims to extend the human senses to machines. This will bring disruptive innovations in the consumer market. Towards that goal, this work examines how the Internet of Things (IoT) can enable digital senses and concentrates on an IoT architecture for the same. The building blocks of the architecture are identified as well as the operating...
Within the last few years, studies on Advanced Driver Assistance Systems (ADAS) have been actively conducted and deployed in modern vehicles; moreover, lane detection and departure warning systems are important modules of ADAS. However, most of the recent papers have only focused on PC-based lane detection modules, and very few concerns have been addressed for the customized embedded board. This paper...
The capability of automated vehicles with intelligent on-board systems aimed at improving traffic safety has been in constant advance. This paper proposes an integrated module of lane and vehicle detection for a forward collision warning system that can be embedded in an autonomous driving system operating in real time. Integration of lane and vehicle detection provides more precise information for...
This paper presents a super-resolution (SR) method for the asymmetric dual-camera system. The proposed method restores the high-resolution (HR) image using the local self-similarity between two input images as wide- and tele-view images. The proposed method consists of three steps: i) registration and warping processes to reduce the disparity between the input images, ii) high-frequency patch extraction...
This work presents the design of an exergaming interface and an assessment tool for the analysis of physical activities. Typically, exergaming aim to engage the user in physical or cognitive activities by qualitative goals that do not take into account the quantitative assessment of the exercise execution. In this work, authors propose an interactive interface which displays a human avatar and returns...
Domestic appliances normally used on daily basis are gradually transitioning into the third internet wave, the internet of things. Usually, the end user is the only qualified actor to identify poor performance of these appliances. Moreover, such bad performance only comes to attention in extreme cases, when the appliance is not functioning anymore. This work describes an intelligent, low cost system,...
