The advance in image/video editing techniques has facilitated people in synthesizing realistic images/videos that may hard to be distinguished from real ones by visual examination. This poses a problem: how to differentiate real images/videos from doctored ones? This is a serious problem because some legal issues may occur if there is no reliable way for(More)
Captions in videos often play an important role in video information indexing and retrieval. In this paper, we present a novel video caption detection approach. We first apply a new Multiple Frames Integration (MFI) method to minimize the variation of the background of the image. A time-based minimum (or maximum) pixel value search is employed and Sobel(More)
Touch is a unique channel in affect conveyance. A significant aspect of this uniqueness is that the relation of touch to affect is immediate, without the need for symbolic encoding and decoding. However, most pioneering research work in developing remote touch technologies, result in the use of touch as a symbolic channel either by design or user decision.(More)
A fault-tolerant (FT) control approach for four-wheel independently-driven (4WID) electric vehicles is presented. An adaptive control based passive fault-tolerant controller is designed to ensure the system stability when an in-wheel motor/motor driver fault happens. As an over-actuated system, it is challenging to isolate the faulty wheel and accurately(More)
This paper investigates whether and how digitally mediated social touch (remote touch) may influence the sense of connectedness toward a speaker and the emotional experience of what is being communicated. We employ an 'augmented' storytelling methodology where we manipulate the modality of an 'emotive' channel that accompanies the speech, and the contextual(More)
The null space property (NSP) and the restricted isometry property (RIP) are two properties which have received considerable attention in the compressed sensing literature. As the name suggests, NSP is a property that depends solely on the null space of the measurement procedure and as such, any two matrices which have the same null space will have NSP if(More)
This year we have participated in all the four tasks including shot boundary determination, story segmentation, high-level feature extraction and video search task. Several low-level visual, audio and text features are extracted for each of the tasks. In order to reduce the semantic gap between low-level features and high-level concepts, we have tried to(More)
Heme binds to amyloid β-peptide (Aβ) in the brain of Alzheimer's disease (AD) patients, thus forming Aβ-heme complexes and leading the characteristic pathological features of AD. The interaction between heme and Aβ might have important biological relevance to AD etiology. In this work, the electrochemical performances of heme after incubation with Aβ1-42,(More)
