Three-Dimensional Contouring of Grid Data by Personal Computer

Three-dimensional computer-automated threshold Amsler grid test.

We describe a novel method for testing a visual field that employs a computer monitor with displays of varying contrast that permits unprecedented resolution and characterization of the structure of scotomas in three dimensions. Patients are placed in front of a touch-sensitive computer screen at a fixed distance. With one eye covered, they focus on a central fixation marker and trace with thei...

Computer vision - three-dimensional data from images

Reading is a hobby to open the knowledge windows. Besides, it can provide the inspiration and spirit to face this life. By this way, concomitant with the technology development, many companies serve the e-book or book in soft file. The system of this book of course will be much easier. No worry to forget bringing the computer vision three dimensional data from images book. You can open the devi...

Computer visualization of three-dimensional image data using IMOD.

We have developed a computer software package, IMOD, as a tool for analyzing and viewing three-dimensional biological image data. IMOD is useful for studying and modeling data from tomographic, serial section, and optical section reconstructions. The software allows image data to be visualized by several different methods. Models of the image data can be visualized by volume or contour surface ...

Human-Computer Interaction with Visualization of Three- Dimensional Medical Data

The 3D data, processed in radiology, requires interaction metaphors different from common user’s needs. In cooperation with medical institutions we have designed a Graphic User Interface (GUI) and Human Input Device (HID), that both address the special requirements of the users. For the GUI we designed new elements to enhances customizability. As a HID we developed an alternative approach for t...
