It is well known that one-dimensional cellular neural networks (1-D CNNs) with the template A = [1, 2,−1] can perform connected component detection (CCD). However this has been confirmed only by numerical and laboratory experiments. In this paper, sufficient conditions for 1-D CNNs to perform CCD are obtained through theoretical analysis. Main result shows that a wide class of templates includi...

The CTIO Prime Focus CCD instrument with an RCA CCD was in operation at the CTIO 4-m telescope for six years between 1982-1988. A large body of literature has been published based on CCD images taken with this instrument. We review the general properties of the now-retired PFCCD system to aid astronomers in the interpretation of the photometric data in the literature.

We report on holographic recording of nanosecond events on a conventional CCD camera. Three frames of an air-discharge event, with resolution of 5.9 ns and frame interval of 12 ns, are recorded in a single CCD frame. Each individual frame is reconstructed by digital filtering of the CCD frame, since successively recorded holograms are centered at different carrier frequencies in the spatial fre...
