Name of the element to describe input parameters. URL of input raster map. Default data format is GeoTIFF. x-y extent of the Gaussian filter. Sensitivity of Gaussian filter. Number of azimuth directions categorized. Type of output GeoTIFF file. The output Format Type is specified as GeoTIFF. Return URL and Format of output raster map. URL of zero crossing raster map. Format of output raster map. Type of output file if the outputFormatType is specified as GeoTIFF. Type of output GeoTIFF file will be Byte - 8-bit unsigned integer. Type of output GeoTIFF file will be Int16 - 16-bit signed integer. Type of output GeoTIFF file will be UInt16 - 16-bit unsigned integer. Type of output GeoTIFF file will be UInt32 - 32-bit unsigned integer. Type of output GeoTIFF file will be Int32 - 32-bit signed integer. Type of output GeoTIFF file will be Float32 - 32-bit floating point. Type of output GeoTIFF file will be Float64 - 64-bit floating point. Type of output GeoTIFF file will be CInt16 - Complex 16-bit signed integer (ie. two Int16's one representing the real component, and one the imaginary component). Type of output GeoTIFF file will be CInt32 - Complex 32-bit signed integer. Type of output GeoTIFF file will be CFloat32 - Complex 32-bit floating point. Type of output GeoTIFF file will be CFloat64 - Complex 64-bit floating point. Find the "edges" in the image. The algorithm used for edge detection is one of the "zero-crossing" algorithms. Provide Zero-crossing "edge detection" raster function for image processing.
