In this paper we consider dense volumetric modeling of moving samples such as body parts. Most dense modeling methods consider samples observed with a moving X-ray device and cannot easily handle moving samples. We propose instead a novel method to observe shape motion from a fixed X-ray device and to build dense in-depth attenuation information. This yields a low-cost, low-dose 3D imaging solution, taking benefit of equipment widely available in clinical environments. Our first innovation is to combine a video-based surface motion capture system with a single low-cost/low-dose fixed planar X-ray device, in order to retrieve the sample motion and attenuation information with minimal radiation exposure...

Research demonstrated that aging services technologies (ASTs) can reduce caregiver burden. However, ASTs are underutilized by caregivers due to poor awareness. This study evaluated the effectiveness of a video-based educational program to increase caregiver AST knowledge among 43 caregivers. Paired sample t-tests showed positive change in AST knowledge, stigma, and intention to engage in AST activities post-program. Caregivers endorsed highly positive AST views pre- and post-program without statistically significant change...

This study compared decision-making (DM) of experienced and novice volleyball coaches while measuring blood flow brain activation with functional near-infrared spectroscopy. We sampled 34 coaches (mean (M) age of 32.5, standard deviation [ SD] = 9.4 years) divided into two experience groups: (a) novice (M = 2.8, SD = 1.9 years) and (b) experienced (M = 19, SD = 7.2 years). We evaluated coaches' DM through their responses to video-based scenarios of attacks performed in the extremities of the net within the Declarative Tactical Knowledge Test in Volleyball...

During face-to-face communication, the mouth of the talker is informative about speech content, while the eyes of the talker convey other information, such as gaze location. Viewers most often fixate either the mouth or the eyes of the talker's face, presumably allowing them to sample these different sources of information. To study the neural correlates of this process, healthy humans freely viewed talking faces while brain activity was measured with BOLD fMRI and eye movements were recorded with a video-based eye tracker...

Alcohol use is a key risk factor for HIV infection among MSM, in part because intoxication may interfere with the use of prevention methods like condoms. However, few studies have examined whether this is due to alcohol's pharmacological or expectancy effects or explored the specific aspects of sexual decision-making that may be affected. In this study, high-risk, heavy drinking MSM (N = 121) were randomly assigned to receive either (1) alcohol beverages, (2) placebo beverages, or (3) control beverages, before navigating a video-based sexual risk scenario that assessed several aspects of sexual decision-making...

BACKGROUND:  In 2011, we implemented a new video-based system for quality control of laparoscopic pyloromyotomy. More than 3 years later, we evaluated how the implementation had gone and assessed its usability in predicting postoperative outcomes. METHODS:  Four key point images or short video-segments were to be recorded perioperatively: prepyloromyotomy, parallel-mobility testing, perforation testing, and postpyloromyotomy. Data of all 134 patients undergoing laparoscopic pyloromyotomy from September 2011 to December 2014 were analyzed retrospectively...

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) presents an alternative model for personality disorders in which severity of personality pathology is evaluated by the Level of Personality Functioning Scale (LPFS). The Structured Interview for the DSM-5 Alternative Model for Personality Disorders, Module I (SCID-5-AMPD I) is a new tool for LPFS assessment, but its interrater reliability (IRR) has not yet been tested. Here we examined the reliability of the Norwegian translation of the SCID-5-AMPD I, applying two different designs: IRR assessment based on ratings of 17 video-recorded SCID-5-AMPD I interviews by five raters; and test-retest IRR based on interviews of 33 patients administered by two different raters within a short interval...

This article proposes an optical measurement of movement applied to data from video recordings of facial expressions of emotion. The approach offers a way to capture motion adapted from the film industry in which markers placed on the skin of the face can be tracked with a pattern-matching algorithm. The method records and postprocesses raw facial movement data (coordinates per frame) of distinctly placed markers and is intended for use in facial expression research (e.g., microexpressions) in laboratory settings...

Video-based person re-identification (re-id) is an important application in practice. Since large variations exist between different pedestrian videos, as well as within each video, it's challenging to conduct re-identification between pedestrian videos. In this paper, we propose a simultaneous intra-video and inter-video distance learning (SI2DL) approach for video-based person re-id. Specifically, SI2DL simultaneously learns an intravideo distance metric and an inter-video distance metric from the training videos...

BACKGROUND: Education on inhaler technique is critical for effective asthma treatment. However, traditionally used face-to-face education is time-consuming, costly, and often laborious. The current study evaluated the efficacy of a newly developed video-based inhaler technique education method. METHODS: A total of 184 subjects with well-controlled or partly-controlled asthma were enrolled from 12 hospitals in South Korea from 30 November 2015 to 01 June 2016. Subjects were randomly divided into two groups in a 1:1 ratio; a control group that received face-to-face education, and a study group that received video education...

This paper presents a system with location functionalities for the inventory of traffic signs based on passive RFID technology. The proposed system simplifies the current video-based techniques, whose requirements regarding visibility are difficult to meet in some scenarios, such as dense urban areas. In addition, the system can be easily extended to consider any other street facilities, such as dumpsters or traffic lights. Furthermore, the system can perform the inventory process at night and at a vehicle's usual speed, thus avoiding interfering with the normal traffic flow of the road...

Micromovements of the eye during visual fixations provide clues about how our visual system acquires information. The analysis of fixational eye movements can thus serve as a noninvasive means to detect age-related or pathological changes in visual processing, which can in turn reflect associated cognitive or neurological disorders. However, the utility of such diagnostic approaches relies on the quality and usability of detection methods applied for the eye movement analysis. Here, we propose a novel method for (micro)saccade detection that is resistant to high-frequency recording noise, a frequent problem in video-based eye tracking in either aged subjects or subjects suffering from a vision-related pathology...

Long-term video-based tracking of single A549 lung cancer cells exposed to three different concentrations of the marine toxin yessotoxin (YTX) reveals significant variation in cytotoxicity, and it confirms the potential genotoxic effects of this toxin. Tracking of single cells subject to various toxic exposure, constitutes a conceptually simple approach to elucidate lineage correlations and sub-populations which are masked in cell bulk analyses. The toxic exposure can here be considered as probing a cell population for properties and change which may include long-term adaptation to treatments...

We present a method for automating the measurement of upper thermal limits in small aquatic organisms. Upper thermal limits are frequently defined by the cessation of movement at high temperature, with measurement being performed by manual observation. Consequently, estimates of upper thermal limits may be subject to error and bias, both within- and among-observers. Our method utilises video-based tracking software to record the movement of individuals when exposed to high, lethal temperature. We develop an algorithm in the R computing language that can objectively identify the loss of locomotory function from tracking data...

Executive Functions (EFs) have been associated with aggression in children and adolescents. EFs as higher-order cognitive abilities are assumed to affect cognitive functions such as Social Information Processing (SIP). We explored SIP skills as a mediating mechanism linking EFs to aggression in adolescents with mild to borderline intellectual disability (MBID with IQ from 50-84), a high risk group for aggressive behaviors and EF impairments. A total of 153 adolescents (Mage  = 15.24, SD = 1.35; 54% male) with MBID participated...
