Descripción
An optimal window for image analysis is determined by means of
information theory. The size of the window is then used as a good
estimator of image quality. The method is sensitive to the size of the
structures present in the image (contrary to the contrast method, widely
used to select the best images of a series) and can provide a quality
map, indicating the zones more or less degraded in the image. In this
letter I describe the optimal window method (OWM) and compare it with
the contrast method, showing a first application to a series of images
taken at Themis IPM.
