clinical photographyThe application of photography, with the exception of radiography, to obtain pictures of parts or the whole of a patient to make a diagnosis.
clinometerAn instrument for measuring the vertical angle of an object. It usually contains an accurately made protractor, a sensitive level bubble, and a sighting device, such as a small telescope.
CLIPcellular logic image processor
clippingA defect in an optical system that prevents rays from reaching their intended destination; it can be caused by an undersized aperture, a baffle out of position, etc. In imaging applications, removing...
clockA signal, generated by an oscillator, that provides the means of synchronization of operations in a data communications network.
closed-circuit television systemA television system that does not broadcast television signals but transmits them over a closed circuit.
closed-loop adaptive single parameterA closed-loop system that compensates for thermal blooming by optimizing only one parameter: the amplitude of the phase correction.
closingIn morphological image processing, a series of dilations followed by the same number of erosions.
