A fast (100 MHz) 1D coded aperture visible light camera has been developed as a prototype for imaging plasma experiments in the EUV/X-ray bands. The system uses printed patterns on transparency sheets as the masked aperture and an 80 channel photodiode array (9 V reverse bias) as the detector. In the low signal limit, the system has demonstrated 40-fold increase in throughput and a signal-to-no...

Rotating line cameras allow to modify camera parameters for adjusting numbers of potential spatial samples within a defined region of interest. The report studies relations between camera parameters and scene parameters, and derives a general approach for designing stereo panoramic cameras. The report also provides a list of problems for further research Acknowledgment. The authors acknowledge ...

Previous work shows that based on ve non-coplanar correspondences of two uncalibrated cameras , 3D reconstruction can be achieved under projec-tive models, or based on four non-coplanar correspondences of two uncalibrated cameras, 3D reconstruction can be achieved under aane models, with three unknown parameters. In this paper, we show that based on four coplanar correspondences of two external...

Most algorithms in 3-D Computer Vision rely on the pinhole camera model because of its simplicity, whereas video optics, especially wide-angle lens, generates a lot of non-linear distortion. In some applications, for instance in stereo vision systems and robotic systems, this distortion can be critical. Camera calibration consists of finding the mapping between the 3-D space and the camera plan...

Dear Editor, The phenotypic appearance of granular corneal dystrophy (GCD) type 1 and GCD type 2 (also known as Avellino corneal dystrophy) changes with age, but is believed to also be influenced by trauma or intervening surgical procedures [1-3]. This report presents two cases of GCD, with varied manifestations before and after surgical intervention. Incidentally, Lee et al. [4] noted high pre...
