WebOct 1, 2024 · Along the same line of research, we present a robust double-weighted guided image filter (RDWGIF) by incorporating the robust edge-aware weighting (REAW) and the mollifier from Sobolev space theory into the cost function of the GIF. WebIn nonparametric statistics, a kernel is a weighting function used in non-parametric estimation techniques. Kernels are used in kernel density estimation to estimate random variables' density functions, or in kernel regression to estimate the conditional expectation of a random variable. Kernels are also used in time-series, in the use of the periodogram to …
