Mask is usually considered to be added in size so that it has a specific center pixel. This mask is moved on the image such that the center of the mask traverses all image pixels. Objective: In the steady-state visual evoked potential (SSVEP)-based brain computer interfaces (BCIs), spatial filtering, which combines the multi-channel electroencephalography (EEG) signals in order to reduce the non-SSVEP-related component and thus enhance the signal-to-noise ratio (SNR), plays an important role in target recognition. 2012-08-13 · Spatial filtering term is the filtering operations that are performed directly on the pixels of an image.
Spatial filtering, beamforming and interference rejection
Filtering techniques are an important part of image processing systems, in particular when it comes to image enhancement and restoration. Here, we only consider linear and spatially invariant systems.

Often times a laser system does not produce a beam with a smooth intensity profile. In order to produce a clean Gaussian beam, a spatial filter is used to remove the unwanted multiple-order energy peaks and pass only the central maximum of the diffraction pattern (see illustration).
Filters point, line, area, and text features based on spatial relationships. Each input Candidate feature is compared against all Filter features, based on the given spatial tests to meet. Features that pass any or all tests are output through the Passed port; all other features are output through the Failed port.
