The ability to communicate is one of the core aspects human life. For this, we use not only verbal but also nonverbal signals remarkable complexity. Among latter, facial expressions belong most important information channels. Despite large variety in daily life, research on has so far mostly focused emotional aspect. Consequently, databases available community include expressions, neglecting largely unexplored aspect conversational expressions. To fill this gap, present MPI expression...

The human face is an important and complex communication channel. Humans can, however, easily read in a not only identity information but also facial expressions with high accuracy. Here, we present the results of four psychophysical experiments which systematically manipulated certain areas video sequences nine conversational to investigate recognition performance its dependency on motions different parts. help demonstrate what perceptually necessary sufficient recognize expressions....

Communication is critical for normal, everyday life. During a conversation, information conveyed in number of ways, including through body, head, and facial changes. While much research has examined these latter forms communication, the majority it focused on static representations few, supposedly universal expressions. Normal conversations, however, contain very wide variety expressions are rarely, if ever, static. Here, we report several experiments that show use eye, internal motion...

Abstract This survey provides an overview of perceptually motivated techniques for the visualization medical image data, including physics‐based lighting as well illustrative rendering that incorporate spatial depth and shape cues. Additionally, we discuss evaluations were conducted in order to study perceptual effects these compared conventional techniques. These assessed perception with judgment, orientation matching, related tasks. existing their evaluation serves a basis defining process...

Most events are processed by a number of neural pathways. These pathways often differ considerably in processing speed. Thus, coherent perception requires some form synchronization mechanism. Moreover, this mechanism must be flexible, because speed changes over the life an organism. Here we provide behavioral evidence that humans can adapt to new intersensory temporal relationship (which was artificially produced delaying visual feedback). The conflict between these results and previous work...

The human face is capable of producing an astonishing variety expressions—expressions for which sometimes the smallest difference changes perceived meaning considerably. Producing realistic-looking facial animations that are able to transmit this degree complexity continues be a challenging research topic in computer graphics. One important question remains answered is: When good enough? Here we present integrated framework psychophysical experiments used first step systematically evaluate...

Rapid and accurate visuomotor coordination requires tight spatial temporal sensorimotor synchronization. The introduction of a or intersensory misalignment (either temporal) impairs performance on most tasks. For more than century, it has been known that few minutes exposure to can induce recalibration relationships, phenomenon may be referred as adaptation. Here, we use high-fidelity driving simulator demonstrate the system adapt misalignments very complex tasks, refer We adapting single...

We present a method for image interpolation that is able to create high-quality, perceptually convincing transitions between recorded images. By implementing concepts derived from human vision, the problem of physically correct relaxed which perceived as visually by observers. find it suffices focus on exact edge correspondences, homogeneous regions and coherent motion compute results. A user study confirms visual quality proposed approach. show how each aspect our approach increases result....

We present the Cardiff Conversation Database (CCDb), a unique 2D audiovisual database containing natural conversations between pairs of people. The currently contains 30 conversations. To date, eight are fully annotated for speaker activity, facial expressions, head motion, and non-verbal utterances. In this paper we describe data collection annotation process. also provide results baseline experiments in which an SVM classifier was used to identify parts recordings from frontchannel...

Comfortable, high-quality 3D stereo viewing is becoming a requirement for interactive applications today. Previous research shows that manipulating disparity can alleviate some of the discomfort caused by stereo, but it best to do this locally, around object user gazing at. The main challenge thus develop gaze predictor in demanding context real-time, heavily task-oriented such as games. Our key observation player actions are highly correlated with present state game, encoded game variables....

Lighting has been used to enhance emotion and appeal of characters for centuries, from paintings in the Renaissance modern-day digital arts. In VFX animation studios, lighting is considered as important modelling, shading, or rigging. Most existing work focuses on either empirical best-practice created by artists centuries perception with basic shapes. contrast, our effect emotional characters. Our study presents an extensive set novel perceptual experiments designed investigate effects...

Evaluation of five types silicon photodiode was undertaken to verify their suitability for absolute radiometry and also use as transfer standards in the spectral region from 1 nm 1100 nm. Four were fabricated this study; these p-on-n photodiode, n-on-p photodiodes with dioxide front windows a metal-silicide window. Fabrication 100% internal quantum efficiency is demonstrated necessity making radiometric measurements lowest possible uncertainty pointed out. The linearity characteristics...

Communication plays a central role in everday life. During an average conversation, information is exchanged variety of ways, including through facial motion. Here, we employ custom, model-based image manipulation technique to selectively “freez ” portions face video recordings order determine the areas that are sufficient for proper recognition nine conversational expressions. The results show most expressions rely primarily on single area convey meaning with different using areas. also...

The goal of stylization is to provide an abstracted representation image that highlights specific types visual information. Recent advances in computer graphics techniques have made it possible render many varieties stylized imagery efficiently making into a useful technique, not only for artistic, but also visualization applications. In this paper, we report results from two sets experiments aim at characterizing the perceptual impact and effectiveness three different context dynamic facial...

Conversing with others is one of the most central human behaviours. In any conversation, humans use facial motion to help modify what said, control flow a dialog, or convey complex intentions without saying word. Here, we employ custom, image-based, stereo motion-tracking algorithm track and selectively "freeze" portions an actor actress's face in video recordings order determine necessary sufficient motions for nine conversational expressions. The results show that expressions rely...

The effects of gaze eccentricity on the steering an automobile were studied. Drivers performed attention task while attempting to drive down middle a straight road in simulation. Steering was biased direction fixation, and deviation from center proportional until saturation at approximately 15° gaze-angle ahead. This effect remains when position head controlled reverse-steering used. Furthermore, not dependent speed but reversed forward movement driver removed Thus, small deviations driver’s...
