M. Corbalan et al., COLOR IMAGE ACQUISITION BY CHARGE-COUPLED-DEVICE CAMERAS IN POLYCHROMATIC PATTERN-RECOGNITION, Optical engineering, 35(3), 1996, pp. 754-760
The influence of the image acquisition by a color CCD camera in color
pattern recognition is studied. Two different types of cameras are use
d: a camera with a single CCD element and color filters (1CCD camera),
and a camera with dichroic mirrors and three CCD elements (3CCD camer
a). Two problems are considered: in the first problem, both the target
and the scene are captured by the camera; in the second problem, only
the scene is captured by the camera and the target is computer genera
ted. A wide range of gain/offset values are used for image acquisition
and pattern recognition results are obtained by computer simulation.
The results reveal that the 3CCD camera is much more suitable than the
1CCD camera for pattern recognition purposes. (C) 1996 Society of Pho
