Stereoscopic liver surface reconstruction
The paper presents a practical approach to measuring liver motion, both respiratory and laparoscopic, with a tool guided in the operating room. The presented method is based on standard operating room equipment, i.e. rigid laparoscopic cameras and a single incision laparoscopic surgery trocar. The triangulation algorithm is used and stereo correspondence points are marked manually by two indepe...
متن کاملStereoscopic Surface Perception
Physiological, computational, and psychophysical studies of stereopsis have assumed that the perceived surface structure of binocularly viewed images is primarily specified by the pattern of binocular disparities in the two eyes' views. A novel set of stereoscopic phenomena are reported that demonstrate the insufficiency of this view. It is shown that the visual system computes the contrast rel...
متن کاملSpeed Discrimination of Stereoscopic (Cyclopean) Motion
This study investigated the degree to which speed of stereoscopic translational motion (i.e. moving binocular disparity information) can be discriminated in a display that minimizes position information. Observers viewed dynamic random-element stereograms depicting arrays of randomly positioned stereoscopic dots that moved bidirectionally. Two tasks were performed: a speed discrimination task a...
متن کاملThe Interactive Spatial Surface - Blended Interaction on a Stereoscopic Multi-Touch Surface
Current touch technology provides precise and accurate large multi-touch surfaces, which allow multiple users to collaborate in these two-dimensional setups. Furthermore, recent developments in the field of display technology support visualization of three-dimensional (3D) virtual environments (VEs) in high-fidelity visual detail on these surfaces. Finally, cost-efficient depth cameras such as ...
متن کاملStereoscopic depth discrimination with contrast windowed stimuli
Depth discrimination with a shifted contrast window was compared to that with a fixed contrast window. Stereoscopic performance with the fixed window was limited to small disparities and varied with spatial frequency. Performance with the shifted window extended to larger disparities and was more similar for low and high spatial frequencies. The results depended upon window shape, indicating th...
