Finite Hilbert Transform in Weighted L2 Spaces
This work addresses mathematical challenges in imaging applications, such as half-scan techniques, but appears incremental as it builds on existing transform theory.
The paper tackles the problem of analyzing and inverting the finite Hilbert transform in weighted L2 spaces, deriving new properties like Plancherel-like equations and coerciveness, and constructing iterative sequences for inversion with simulation results for specific parameters.
Several new properties of weighted Hilbert transform are obtained. If mu is zero, two Plancherel-like equations and the isotropic properties are derived. For mu is real number, a coerciveness is derived and two iterative sequences are constructed to find the inversion. The proposed iterative sequences are applicable to the case of pure imaginary constant mu=i*eta with |eta|<pi/4 . For mu=0.0 and 3.0 , we present the computer simulation results by using the Chebyshev series representation of finite Hilbert transform. The results in this paper are useful to the half scan in several imaging applications.
