Abstract We developed a rich dataset of Chest X-Ray (CXR) images to assist investigators in artificial intelligence. The data were collected using an eye-tracking system while radiologist reviewed and reported on 1,083 CXR images. contains the following aligned data: image, transcribed radiology report text, radiologist’s dictation audio eye gaze coordinates data. hope this can contribute vario...

In this paper, a new iris localization method for mobile devices is presented. Our system uses both intensity and saturation threshold on the captured eye images to determine iris boundary and sclera area, respectively. Estimated iris boundary pixels which have been placed outside the sclera will be removed. The remaining pixels are mainly the boundary of iris inside the sclera. Then, circular ...

A major goal of systems neuroscience is to describe neural representations of the environment that mediate perception. An experimental strategy adopted by researchers involved in this effort is to obtain three-dimensional correlations between the physical properties of a stimulus, a psychophysical report of the subject, and measures of intervening neural events. Perception is, of course, a priv...

Human sound localization relies on implicit head-centered acoustic cues. However, to create a stable and accurate representation of sounds despite intervening head movements, the acoustic input should be continuously combined with feedback signals about changes in head orientation. Alternatively, the auditory target coordinates could be updated in advance by using either the preprogrammed gaze-...

This paper describes the effect of spectro-temporal factors on human sound localization performance in two dimensions (2D). Subjects responded with saccadic eye movements to acoustic stimuli presented in the frontal hemisphere. Both the horizontal (azimuth) and vertical (elevation) stimulus location were varied randomly. Three types of stimuli were used, having different spectro-temporal patter...

Passive deviation of one eye through 18 degrees, 30 degrees and 42 degrees, achieved by force applied to a sucked-on contact lens, caused the direction of visual targets seen by the other eye to be misjudged in the direction of the passive movement by an amount roughly one-sixth of the angle of passive deviation. The result was the same when the perceived direction was indicated by hand, as whe...

This work presents methods for tracking a ball from noisy data taken by robots. In robotic soccer, getting a good estimation of a ball’s position is a critical. In addition, accurate ball tracking enables robots to play well, for example, efficiently passing to other robots, fine saves by the goalie, good team play, and so on. In this paper, we present new ball tracking technique based on Monte...

− Autostereoscopic display systems can provide users a natural 3-D visualization environment by projecting stereo video onto the user's eyes. Eye position localization is a central module in this kind of display system when users are allowed to move freely. This paper presents robust 3-D eye tracking techniques that can provide accurate eye positions in real time. Technical batteries comprise: ...

This paper presents an eye detection technique basedon color and shape features. The approach consists of three steps: a rough eye localization using projection technique, a white color thresholding to extract white sclera, and an ellipse fitting to fit the ellipse shape of eye. The proposed white color thresholding utilizes the normalized RGB chromaticty diagram, where white color objects are ...
