Alessandro Giusti and I are developing the Java+OpenGL powered viewer technology behind L3 HyperView. L3 HyperView is an userfriendly viewer for gigapixel-class images with smooth pan, zoom, rotation and innovative input interfaces.
Leonardo3 HyperView premiered on 12-20 May 2007 at Biblioteca Reale, Torino during the "Codex on flight" exposition, where very high resolution images were displayed on Full High-Definition HDTV screens.
Learn more at L3 homepage and the exposition page (includes photos, press release and video of national TV coverage by RAI3 TG3 Leonardo).

Givan: Localizing 3D straight lines from single 2D images |
|
We present an algorithm that can be used to localize the position in the space of straight lines from a single 2D image. This reconstruction is possible if the image is retrieved using a special camera apparatus. In particular this work focuses on axial catadioptric cameras since for this kind of cameras it is possible to demonstrate that the straight lines localization is always possible with the only exception of particular lines as, for example, those coplanar with the camera axis. The work, then, presents how to cope with the error present in the image that represents the contours of the original image. This is done by applying an optimization algorithm using a particular error function. In the end we present an algorithm used to simulate the image retrieval and the equation of a set of mirrors used in conjunction with the camera.

Siso - single in sigle out dynamic systems simulator |
|
Siso is a real time analisys application for linear dynamic systems with a single input and a single output. The application allow the user to easily change a given system with simple mouse gestures. The system is represented by different views that describe its different aspects and the user has the faculty to select a subset of them. The software was written in Java using OpenGL (thorugh the wrapper library gl4java) in collaboration with Alessandro DiGioia. |
