3-D building reconstruction with ARUBA: a qualitative and quantitative evaluation
(1997)Automatic Extraction of Man-Made Objects from Aerial and Space Images (II)Reliable and accurate 3-D reconstruction of man-made objects is essential for many applications using digital 3-D city models. Manual reconstruction of buildings from aerial images is time consuming and requires skilled personnel, hence large efforts are being directed towards the automation of building detection and reconstruction. In this paper we present ARUBA — a framework for automated 3-D building reconstruction. After highlighting ...Conference Paper -
Image-based reconstruction of informal settlements
(1997)Automatic Extraction of Man-Made Objects from Aerial and Space Images (II)The improvement of living conditions in informal settlements (IS) is one of the most complex and pressing challenges facing developing countries. In this paper we report on progress towards the automated generation of geospatial databases of informal settlements from large scale, low cost, digital still-video imagery. We focus on shack extraction as the predominant data requirement. In contrast to western residential environments where ...Conference Paper -
High power continuous wave operation of mid-infrared quantum cascade lasers
(1997)Proceedings of the 1997 10th IEEE Lasers and Electro-Optics Society Annual Meeting (LEOS)In recent years laser emission from unipolar quantum cascade (QC) structures has been demonstrated in a wide range of wavelengths and temperatures. Continuous wave (CW) operation has also been reported, but with limited output powers (a few tens of mW). We present here the results obtained on a mid-infrared QC laser, whose design has been carefully optimized in order to maximize the injection efficiency and the gain. The device employs a ...Conference Paper
