Binomial Gaussian mixture filter [PDF]
EURASIP Journal on Advances in Signal Processing, 2015 In this work, we present a novel method for approximating a normal distribution with a weighted sum of normal distributions. The approximation is used for splitting normally distributed components in a Gaussian mixture filter, such that components have smaller covariances and cause smaller linearization errors when nonlinear measurements are used for ...

Recursive Gaussian derivative filters
Proceedings. Fourteenth International Conference on Pattern Recognition (Cat. No.98EX170), 2002 We propose a strategy to design recursive implementations of the Gaussian filter and Gaussian regularized derivative filters. Each recursive filter consists of a cascade of two stable Nth-order subsystems (causal and anti-causal). The computational complexity is 2N multiplications per pixel per dimension independent of the size (/spl sigma/) of the ...
