Image Manipulations
After the raw image data are calibrated into relative intensive values
several operations may be applied to frames to enhance features which
later should be studied. This involves manipulations with the
Signal-to-Noise ratio (S/N), resolution, and coordinates of the
images. Further, real but disturbing features may be removed to allow
a better access to the objects of interest. The typical methods
include digital filtering, coordinate transformations, and image
restoration.
