Adaptive behavior guided by unconscious visual cues occurs in patients with various kinds of brain damage as well as in normal observers, all of whom can process visual information of which they are fully unaware [1] [2] [3] [4] [5] [6] [7] [8]. Little is known on the possibility that unconscious vision is influenced by visual cues that have access to consciousness [9]. Here we report a 'blind'...

Optical flow color coding. For optical flow visualization we use the color coding of Butler et al. [3]. The color coding scheme is illustrated in Figure 1. Hue represents the direction of the displacement vector, while the intensity of the color represents its magnitude. White color corresponds to no motion. Because the range of motions is very different in different image sequences, we scale t...

Photographers suffer from many challenging problems when separating and compositing images, such as the color camouflage and unpleasant color bleeding artifacts. To tackle these issues, we present a solution to foreand background segmentation for images taken from multiple cameras, which introduce the parallax that leads to the foreground model projecting to different background locations, whic...

Airborne Light Detection and Ranging (LiDAR) is used in many 3D applications, such as urban planning, city modeling, facility management, and environmental assessments. LiDAR systems generate dense 3D point clouds, which provide a distinct and comprehensive geometrical description of object surfaces. However, the challenge is that most of the applications require correct identification and extr...

Laboratory and flight test evaluations have consistently demonstrated the potential for helmet-mounted display (HMD) presented information to enhance air combat performance. The Air Force Research LaboratoryÕs (AFRLÕs) Helmet-Mounted Sight Plus (HMS+) program seeks to provide further enhancement by enabling the presentation of multi-color symbology and sensor imagery. To take proper advantage o...

In grapheme-color synesthesia, seeing particular letters or numbers evokes the experience of specific colors. We investigate the brain's real-time processing of words in this population by recording event-related brain potentials (ERPs) from 15 grapheme-color synesthetes and 15 controls as they judged the validity of word pairs ('yellow banana' vs. 'blue banana') presented under high and low vi...

OBJECTIVE Computational models of identification and relative comparison tasks performed on color-coded data visualizations were presented and evaluated against two experiments. In this context, the possibility of a dual-use color scale, useful for both tasks, was explored, and the use of the legend was a major focus. BACKGROUND Multicolored scales are superior to ordered brightness scales fo...

This paper will present a visualization tool for comparing images of paintings. The method starts with two types of images, one showing the color surface, the other the underdrawing the first concept of a painting. The purpose of the tool is to support art historians in understanding differences and similarities of the preliminary sketches and the final painting. The algorithm consists of two c...

motor imagery is the ability to imagine performing a movement without any action. the time a movement is mentally rehearsed highly correlates with the actual time of motor action. in this study, the effect of voluntary changes in imagery speed on the duration of the actual performance and learning a complex unfamiliar skill, and also the difference between the effects of real-time and fast imag...
