GisPixelFilter classes

Classes

Name Description
TGIS_PixelFilterAbstract Abstract class for all pixel layer filters.
TGIS_PixelFilterAlphaTrimmedMean Alpha-trimmed mean filter for pixel layers - transforms the pixel value to the alpha-trimmed mean of the values within the block.
TGIS_PixelFilterArithmeticMean Arithmetic mean filter for pixel layers - transforms the pixel value to the arithmetic mean of the values within the block.
TGIS_PixelFilterBlockStats Abstract class for all pixel layer block filters.
TGIS_PixelFilterBottomHat Bottom-hat filter for pixel layers - three-stage filter, computes the difference of the closing (dilation followed by erosion) of the image with the original image.
TGIS_PixelFilterClosing Closing filter for pixel layers - two-stage filter, applies dilation followed by erosion.
TGIS_PixelFilterContraHarmonicMean Contra-harmonic mean filter for pixel layers - transforms the pixel value to the contra-harmonic mean of the values within the block.
TGIS_PixelFilterConvolution Applies mask filters to pixel layers by convolution.
TGIS_PixelFilterDilation Dilation filter for pixel layers - transforms the pixel value to the greatest sum of the value in the block and the mask value.
TGIS_PixelFilterErosion Erosion filter for pixel layers - transforms the pixel value to the smallest difference of the value in the block and the mask value.
TGIS_PixelFilterGeometricMean Geometric mean filter for pixel layers - transforms the pixel value to the geometric mean of the values within the block.
TGIS_PixelFilterHarmonicMean Harmonic mean filter for pixel layers - transforms the pixel value to the harmonic mean of the values within the block.
TGIS_PixelFilterMajority Majority filter for pixel layers - transforms the pixel value to the most frequent value in the block (if exists).
TGIS_PixelFilterMaximum Maximum filter for pixel layers - transforms the pixel value to the greatest value in the block.
TGIS_PixelFilterMedian Median filter for pixel layers - transforms the pixel value to the median of the values within the block.
TGIS_PixelFilterMidpoint Midpoint filter for pixel layers - transforms the pixel value to the average between the maximum and the minimum value in the block.
TGIS_PixelFilterMinimum Minimum filter for pixel layers - transforms the pixel value to the smallest value in the block.
TGIS_PixelFilterMinority Minority filter for pixel layers- transforms the pixel value to the least frequent value in the block (if exists).
TGIS_PixelFilterMorphological Abstract class for all pixel layer morphological filters.
TGIS_PixelFilterNoise Abstract class for all noise pixel layer filters.
TGIS_PixelFilterNoiseGaussian Gaussian noise filter for pixel layers.
TGIS_PixelFilterNoiseSaltPepper Salt-And-Pepper noise filter for pixel layers.
TGIS_PixelFilterOpening Opening filter for pixel layers - two-stage filter, applies erosion followed by dilation.
TGIS_PixelFilterRange Range filter for pixel layers - transforms the pixel value to the difference between the maximum and the minimum value in the block.
TGIS_PixelFilterSobelMagnitude Sobel magnitude filter for pixel layers - performs edge detection, the pixel value is proportional to the value difference at the edge.
TGIS_PixelFilterStandardDeviation Standard deviation filter for pixel layers - transforms the pixel value to the standard deviation of the values within the block.
TGIS_PixelFilterSum Sum filter for pixel layers - transforms the pixel value to the sum of the values within the block.
TGIS_PixelFilterThreshold Threshold filter for pixel layers - if the pixel value is smaller than the threshold then it is set to the smallest value in the layer, otherwise to the largest.
TGIS_PixelFilterTopHat Top-hat filter for pixel layers - three-stage filter, computes the difference of the original image with its opening (erosion followed by dilation).
TGIS_PixelFilterUniqueCount Unique value count filter for pixel layers - transforms the pixel value to the number of unique values within the block.
TGIS_PixelFilterWeightedMean Weighted mean filter for pixel layers - transforms the pixel value to the weighted mean of the values within the block.
TGIS_PixelFilterWeightedMedian Weighted median filter for pixel layers - transforms the pixel value to the weighted median of the values within the block.
TGIS_PixelFilterYpMean Yp mean filter for pixel layers - transforms the pixel value to the Yp mean of the values within the block.
