Parallel implementation of multifilters
A multi lter is a lter with matrix-valued coe cients, and is used in the processing of vector-valued signals, e.g. color images. Convolution becomes a vector sum of matrix-vector multiplication. In this paper, we e ciently implement a multi lter as a parallel combination of scalar lters. Each scalar lter works on one component of the input vector signal, which increases processing speed by the ...
متن کاملDesign of perfect reconstruction FIR multifilters
The design of perfect reconstruction FIR multi lters is discussed in this paper. Schur algorithm is applied to factorize the polyphase matrix of multi lters into lattice blocks. The multi lters are characterized by the chain parameters in each lattice block. The complete parameterization of paraunitary multi lters and a class of biorthogonal multilters are derived. The parameterizations are min...
متن کاملp38 MAPK and PI3K/AKT signalling cascades in Parkinson’s disease
Parkinson's disease (PD) is a chronic neurodegenerative condition which has the second largest incidence rate among all other neurodegenerative disorders barring Alzheimer's disease (AD). Currently there is no cure and researchers continue to probe the therapeutic prospect in cell cultures and animal models of PD. Out of several factors contributing to PD prognosis, the role of p38 MAPKs (mitog...
متن کاملThe estimation of the Sunyaev–Zel’dovich effects with unbiased multifilters
In this work we study the performance of linear multifilters for the estimation of the amplitudes of the thermal and kinematic Sunyaev–Zel’dovich (SZ) effects. We show that when both effects are present, estimation of these effects with standard matched multifilters is intrinsically biased. This bias is due to the fact that both signals have basically the same spatial profile. We find a new fam...
