Estimation of rotation angle on image superposition by using mixed coordinate system
Journal Title: Вісник НТУУ КПІ. Серія Радіотехніка, Радіоапаратобудування - Year 2010, Vol 0, Issue 42
Abstract
Non-search algorithm of image angle estimation is presented. This algorithm improves precision of image angle estimation in wide range in comparison to known algorithms. Images are presented in rectangle system of coordinate and for derivative calculation two symmetrically rotated copies of one image are used. Analysis of algorithm includes investigation of theoretical model and real magneto-optic images.
