Separation of Regional and Residual Components of Bathymetry Using Directonal Median Filtering
I propose a new filtering technique to separate bathymetric data into regional and residual components. Directional median (DiM) filtering divides a given filter circle into N "bow-tie" sectors, allocates the data points inside the filter circle to each bowtie sector based on their relative position with respect to the center of the filter circle, estimates a median value for each sector, and r...
متن کاملSurface denoising with directional fuzzy vector median filtering
This paper proposes a novel approach for smoothing surfaces represented by triangular meshes. The proposed method is a two-step procedure: surface normal smoothing through fuzzy vector median (FVM) filtering followed by vertex position update based on the least square error criteria. This paper applies the fuzzy ordering theory to the vector based data and introduces the fuzzy vector median. Th...
متن کاملSeparation of regional and residual magnetic field data
We present a method for separating regional and residual magnetic fields using a 3-D magnetic inversion algorithm. The separation is achieved by inverting the observed magnetic data from a large area to construct a regional susceptibility distribution. The magnetic field produced by the regional susceptibility model is then used as the regional field, and the residual data are obtained by simpl...
متن کاملResidual Bootstrapping and Median Filtering for Robust Estimation of Gene Networks from Microarray Data
We propose a robust estimation method of gene networks based on microarray gene expression data. It is well-known that microarray data contain a large amount of noise and some outliers that interrupt the estimation of accurate gene networks. In addition, some relationships between genes are nonlinear, and linear models thus are not enough for capturing such a complex structure. In this paper, w...
