Technology for Seamless Multi-Projection onto a Hybrid Screen Composed of Differently Shaped Surface Elements
نویسندگان
چکیده
We describe a tiled-projection display system whose entire image is composed of twenty four patches of projection, sixteen of which are used for front projection and eight of which are used for rear projection on the center area of the screen. Eight pairs of the projectors are used to project stereoscopic images, the left-eye image and the right-eye image. The screen consists of differently shaped surface elements that are the partial surfaces of such objects as planes, spheres, cylinders and tori. The following three technologies were developed for the display system: (1) a digital camera based measurement of the position and the color features of the pixels projected on a screen, (2) software that computes the geometry correction and the color modulation for edge blending by using the measurement data, and (3) real time image processing hardware to enable arbitrary geometrical warping and color modulation for individual pixels.

Bearing in mind that lack of data is a common problem in the study of porphyry copper mining exploration, our goal was set to identify the hidden patterns within the data and to extend the information to the data-less areas. To do this, the combination of pattern recognition techniques has been used. In this work, multi-layer neural network was used to estimate the concentration of geochemical ...

An intelligent design method of double screen frequency selective surfaces (FSSs) is addressed in this paper. The employed unit cell is composed of two metallic screens, which are printed on both sides of a substrate. The presented non-trial-and-error approach is investigated based on the separate design of each screen. With the help of some physical intuition and an equivalent circuit model, i...
