We propose a novel method for fusing different classifiers outputs. Our approach, called Context Extraction for Local Fusion with Fuzzy Integrals (CELF-FI), is a local approach that adapts fuzzy integrals fusion method to different regions of the feature space. It is based on a novel objective function that combines context identification and multi-algorithm fusion criteria into a joint objective...
In this paper, we show the importance of face-voice correlation for audio-visual person recognition. We evaluate the performance of a system which uses the correlation between audio-visual features during speech against audio-only, video-only and audio-visual systems which use audio and visual features independently neglecting the interdependency of a person's spoken utterance and the associated facial...
For a successful real-time vision-based HCI system, inference from natural visual method is crucial. In this paper, we have aimed to provide interaction through gesture and posture recognition for alphabets and numbers. In addition, data fusion is carried out which integrates these systems to extract multiple meanings at the same time. 3D information is exploited for segmentation and detection of...
Pervasive healthcare provides an effective solution for monitoring the wellbeing of elderly, quantifying post-operative patient recovery and monitoring the progression of neurodegenerative diseases such as Parkinson's. However, developing functional pervasive systems is a complex task that entails the creation of appropriate sensing platforms, integration of versatile technologies for data stream...
Commonly, surveillance operators are today monitoring a large number of CCTV screens, trying to solve the complex cognitive tasks of analyzing crowd behavior and detecting threats and other abnormal behavior. Information overload is a rule rather than an exception. Moreover, CCTV footage lacks important indicators revealing certain threats, and can also in other respects be complemented by data from...
In the domain of rail vehicles a robust localization is a fundamental precondition for reasonable actions within operating systems. In addition to reliable sensor measurements an efficient and precise localization is highly dependent on accurate map information. In that context digital maps are often not available in the required quality. Key focus of this contribution is to substitute established...
In this paper, we investigate the mutual-complementary functionality of accelerometer (ACC) and electromyogram (EMG) for recognizing seven word-level sign vocabularies in German sign language (GSL). Results are discussed for the single channels and for feature-level fusion for the bichannel sensor data. For the subject-dependent condition, this fusion method proves to be effective. Most relevant features...
Keystroke dynamics refers to a userpsilas habitual typing characteristics. These typing characteristics are believed to be unique among large populations. In this paper, we present a novel keystroke dynamic recognition system by using a fusion method. Firstly,we record the dwell time and the flight time as the feature data. We then calculate their mean and standard deviation values and stored. The...
