A New Star Removal Method in Airglow Images Using Morphological Operations

N. Venkataramanaiah, S. Varadarajan, T.K. Ramkumar


High intensity amplitudes due to stars introduced background noise in sky images captured by an All sky airglow imager at Gadanki, india(13.50N ,79.20E) . The maped are a of sky overhead at certain wavelengths of airglow emissions to determine characterics of atmospheric gravity waves and also to observe the attributes of ionosphere plasma irregularities/bubles in the upper atmosphere. Even though many investigators used various techniques for eliminating stars from airglow images some stars are still remain.To rise above this a new method for removing stars completely using morphological operations is projeced in this paper for better parametric evolution.
