This paper presents SDHO (scratch detection via harmonic oscillator), a generalized model to detect line scratches on digital images. The line scratch profile is now a solution of a second order homogeneous differential equation, depending exclusively on the width and the brightness of the scratch. This method performs noticeably better than the other existing techniques with a lower computing time.

Abstract
This paper presents SDHO (scratch detection via harmonic oscillator), a generalized model to detect line scratches on digital images. The line scratch profile is now a solution of a second order homogeneous differential equation, depending exclusively on the width and the brightness of the scratch. This method performs noticeably better than the other existing techniques with a lower computing time.File allegati a questo prodotto
