The operator applies the Kurtosis Texture operator on pixels of the input raster that are inside a feature and then computes mean, median and standard deviation of the kurtosis texture values. The computed statistical values are added as attributes to the feature stream.
When computing texture for a feature, only pixels that are inside the feature are considered. If some cells of the moving neighboring window fall outside the feature, as happens when computing texture near the boundary of the feature, these cells are treated as NoData cells during the computation. This ensures pixels in a feature do not affect the texture of adjoining features.
The attribute names for the output feature stream are constructed based on AttributeNamePrefix, AttributeBasename for the statistics being computed and the number of bands of the raster. If the constructed attribute name matches with the name of an existing field and the field type is appropriate, the existing field will be overwritten. otherwise, the operation will fail.
The table below shows different scenarios for mean kurtosis texture attribute name.
WV_KMean1, WV_KTMean2, WV_KTMean3
WV_Average1, WV_Average2, WV_Average3
ZR_KTMean1, ZR_KTMean2, ZR_KTMean3
ZR_Average1, ZR_Average2, ZR_Average3
A 3X3 moving window is used to calculate the per-pixel texture.
The operator only works for AreaGeometry field types. An error is generated otherwise.
Features whose primary geometry field will be used to define zones in the Input raster.
Input raster that will be used to compute kurtosis texture.
Flag to compute average mean euclidean distance texture. The averagekurtosis texture will added as an attribute of double precision floating point type.
Attribute name for the mean kurtosis texture in FeaturesOut.
Flag to compute median kurtosis texture. The median kurtosis texture will added as an attribute of double precision floating point type.
Attribute name for median kurtosis texture in FeaturesOut.
Flag to compute standard deviation of the kurtosis texture. The standard deviation of the kurtosis texture will added as an attribute of double precision floating point type.
Attribute name for standard deviation of the kurtosis texture in FeaturesOut.
Prefix for attribute names. The string will be prepended to the attribute basenames.
The input features updated to include the computed texture statistics as additional attributes.
