Survey of Astronomical Image Processing Methods [PDF]
Lecture Notes in Computer Science, 2015 The image processing is becoming a key issue in astronomical data analysis. This paper introduces the algorithms and methods applied in astronomical image processing from different aspects. The paper first shows methods of lossless compression of astronomical images, like the pyramidal median transform, segment-based DPCM and 5/3 integer wavelet ...
