FILTERS See also Filters: filterBinomial1d - 1D binomial filter (approximation to Gaussian filter) filterDog2d - Difference of Gaussian (Dog) Filter. filterDoog - n-dim difference of offset Gaussian DooG filter (Gaussian derivative). filterGabor1d - Creates an even/odd pair of 1D Gabor filters. filterGabor2d - Creates an even/odd pair of 2D Gabor filters. filterGauss - n-dimensional Gaussian filter. filterSteerable - Steerable 2D Gaussian derivative filter (for visualization). filterVisualize - Used to visualize a 1D/2D/3D filter. Operations involving a set of filters (a filter bank or FB): FbApply2d - Applies each of the filters in the filterbank FB to the image I. FbCrop - Crop a 2D filterbank (adjusting filter norms). FbMake - Various 1D/2D/3D filterbanks (hardcoded). FbReconstruct2d - Use to see how much image information is preserved in filter outputs. FbVisualize - Used to visualize a series of 1D/2D/3D filters. Simple nonlinear filters: medfilt1m - One-dimensional adaptive median filtering with missing values. modefilt1 - One-dimensional mode filtering.
