Query: Separation Surfaces in the Spectral TV Domain for Texture Decomposition   In this paper we introduce a novel notion of separation surfaces for image
decomposition. A surface is embedded in the spectral total-variation (TV) three
dimensional domain and encodes a spatially-varying separation scale. The method
allows good separation of textures with gradually varying pattern-size,
pattern-contrast or illumination. The recently proposed total variation
spectral framework is used to decompose the image into a continuum of textural
scales. A desired texture, within a scale range, is found by fitting a surface
to the local maximal responses in the spectral domain. A band above and below
the surface, referred to as the \textit{Texture Stratum}, defines for each
pixel the adaptive scale-range of the texture. Based on the decomposition an
application is proposed which can attenuate or enhance textures in the image in
a very natural and visually convincing manner.
