Dual filtering includes spatial filtering via a pinhole (22) and spatial filtering operated by a fast gate (24).
The flash suppression mechanism is spatial filtering.
Eyewear which preferentially transmits light from a liquid crystal display screen using spectral filtering, polarization filtering and/or spatial filtering.
Image data to be output to an external device is subjected to a spatial filtering having an output dynamic range wider than input by a spatial filtering section (201).
The filter unit (58) carries out a spatial filtering operation and outputs the result.
The eyewear transmits using spectral filtering, polarization filtering.
Thereby, the advantages of a spatial and a temporal filtering at different vertical frequencies can be combined.
A method of spatially filtering an image using an adaptive convolution filter is disclosed.
Said subtraction is carried out by means of a co-ordinated spatial filtration of the distorted image.
The present invention relates to a spatial domain matched filtering method.
Spatial beam cleanup and passive locking are simultaneously achieved.
Filtering means (4) carries out a space filtering of the brightness acquired by the conversion by the first color conversion means (2).
A low-pass spatial filtration (125) of the fourth output (121) is performed to generate a fifth output (126).
The compensation of said distortions is carried out with the aid of an adjusted spatial filtration of the intermediate distorted image (3 and 3 1).
A color saturation and correction (130) of the fifth output (126) is performed to generate a sixth output (131), and a high-pass spatial filtration (135) of the sixth output (131) is performed to generate an image output (136).
Spatial and/or colour filtering of the real world images is implemented to reduce computational intensity.
It is described a method for spatially filtering 3D seabed seismic data acquired in a cross-line geometry including methods of how to decompose the data using a filter with two spatial components.
An optical modulating system (26) allows modulation of a single light beam (16) with a spatially filtering mask (47) to form a spatially periodic, time dependent excitation field.
Such acceleration is applicable to, and useful in conjunction with assembly of the data, in performing both spatial filtration and temporal filtration (24) of the assembled data, and in processing the data, once acquired.
