The relationship between liking and stimulus complexity is commonly reported to follow an inverted U-curve. However, large individual differences among preferences of participants have frequently been observed since the earliest studies on topic. common use across-participant analysis methods that ignore these in aesthetic gives impression high agreement individuals. In this study, we collected ratings perceived from 30 for a set digitally generated grayscale images. addition, calculated...
Personality analysis has been widely studied in psychology, neuropsychology, and signal processing fields, among others. From the past few years, it also became an attractive research area visual computing. computational point of view, by far speech text have most considered cues information for analyzing personality. However, recently there increasing interest from computer vision community personality data. Recent approaches are able to accurately analyze human faces, body postures...
Various studies on the hand laterality judgment task, using complex sets of stimuli, have shown that judgments during this task are dependent bodily constraints. More specific, these showed reaction times participant's posture or differ for pictures rotated away toward mid-sagittal plane (i.e., lateral medial rotation, respectively). These findings point to use a cognitive embodied process referred as motor imagery. We hypothesize number axes rotation displayed stimuli is critical factor...
People form first impressions about the personalities of unfamiliar individuals even after very brief interactions with them. In this study we present and evaluate several models that mimic automatic social behavior. Specifically, trained on a large dataset short YouTube video blog posts for predicting apparent Big Five personality traits people whether they seem suitable to be recommended job interview. Along presenting our audiovisual approach results won third place in ChaLearn First...
Explainability and interpretability are two critical aspects of decision support systems. Despite their importance, it is only recently that researchers starting to explore these aspects. This paper provides an introduction explainability in the context apparent personality recognition. To best our knowledge, this first effort direction. We describe a challenge we organized on impressions analysis from video. analyze detail newly introduced data set, evaluation protocol, proposed solutions...
The phenomenon of visual occlusion has frequently been studied by means two-dimensional line drawings. These drawings may elicit various interpretations. Sometimes a mosaic shapes is seen, sometimes shape that partly occludes another shape. In the latter case, observers often have clear idea about form occluded Local and global pattern aspects both seem to be decisive with respect preferred interpretation. An attempt made integrate these applying global-minimum principle perceptual...
Objects in our world are partly occluded by other objects or sometimes even themselves. Amodal completion is a visual process that enables us to perceive these as complete and influenced both local object information, present at contour intersections, overall (global) shape. In contrast, semantics have been demonstrated play no role amodal but do so only means of subjective methods. the study, were operationalised material hardness familiar which was varied test whether it leaves unaffected....
Abstract We investigated motion extrapolation in object tracking two experiments. In Experiment 1, we used a multiple-object-tracking task (MOT; three targets, distractors) combined with probe detection to investigate the distribution of attention around target object. found anisotropic rates increased at locations where is heading. 2, introduced black line (wall) center screen and block-wise manipulated object's motion: either objects bounced realistically against wall or went through wall....
We studied the effects of learning on amodal completion partly occluded shapes. Amodal may originate from local characteristics contours, resulting in completions, or global characteristics, completions. Two classes occlusion patterns were constructed: convergent patterns, which and completions resulted same shape, much more ambiguous divergent these different used a sequential matching paradigm obtained behavioral responses (Experiment 1s 2) electroencephalogram recordings 3) to investigate...
This paper reviews and discusses research advances on "explainable machine learning" in computer vision. We focus a particular area of the "Looking at People" (LAP) thematic domain: first impressions personality analysis. Our aim is to make computational intelligence vision communities aware importance developing explanatory mechanisms for computer-assisted decision making applications, such as automating recruitment. Judgments based traits are being made routinely by human resource...
Reflective displays that rely on ambient light as opposed to an internal source have been making inroads for a variety of important applications, especially those involving mobility where power usage must be aggressively controlled. The underlying color rendering strategies both reflective and emissive largely the same, combining three fixed, primary subpixels compose rich gamut users expect. result, displays, is unfavorable brightness/gamut performance since each absorbs roughly 2/3...
Eye movements can have serious confounding effects in cognitive neuroscience experiments. Therefore, participants are commonly asked to fixate. Regardless, will make so-called fixational eye under attempted fixation, which thought be necessary prevent perceptual fading. Neural changes related these could potentially explain previously reported neural decoding and neuroimaging results fixation. In previous work, fixation passive viewing, we found no evidence for systematic movements. Here,...
When solid objects are viewed from only one direction, some parts necessarily occluded. Expectations about possible completions of novel (cubes with indentations) were measured by the response times to determine whether two images could be depth-rotated views same object. Completions considered global if completed indentations identical visible (i.e., they globally simple because repetitions) and local locally (e.g., straight contours a minimal number additional surfaces). The results three...
Explainability and interpretability are two critical aspects of decision support systems. Within computer vision, they in certain tasks related to human behavior analysis such as health care applications. Despite their importance, it is only recently that researchers starting explore these aspects. This paper provides an introduction explainability the context vision with emphasis on looking at people tasks. Specifically, we review study those mechanisms first impressions analysis. To best...
We investigated here how partly occluded stimuli affect early and late prehension kinematics. Stimuli were pictures of cylindrical objects with indentations or protrusions at regular intervals along the contour. They diverged into two plausible completions: a local completion, comprising linear continuation contour, global revealing contour indentations. Convergent one completion acted as controls. Twenty-eight participants repeatedly performed grasping movement in darkness, if they grasped...
