Image decomposition and staircase effect reduction based on total generalized variation
Journal of Systems Engineering and Electronics(2014)
摘要
Total variation (TV) is widely applied in image processing. The assumption of TV is that an image consists of piecewise constants, however, it suffers from the so-called staircase effect. In order to reduce the staircase effect and preserve the edges when textures of image are extracted, a new image decomposition model is proposed in this paper. The proposed model is based on the total generalized...
