FELEE FFROST FGAMMA KUAN FLE FME FMO FPR FPRE SHARP FSOBEL FSPEC LINE SIEVE MODEL ARI Enhanced Lee Adaptive Filtering (up to 11x11), Performs enhanced Lee adaptive filtering on image data. The enhanced Lee Filter is primarily used on radar data to remove high frequency noise (speckle) while preserving high frequency features (edges). Frost Adaptive Filtering (up to 33x33) FFROST is used primarily to filter speckled SAR data. An adaptive Frost filter smooths image data, without removing edges or sharp features in the images. Gamma Filtering (up to 11x11), Performs gamma map filtering on image data. The gamma map filter is primarily used on radar data to remove high frequency noise (speckle) while preserving high frequency features (edges). Kuan Filtering (up to 11x11), Performs Kuan filtering on image data. The Kuan filter is primarily used on radar data to remove high frequency noise (speckle) while preserving high frequency features (edges). Lee Adaptive Filtering (up to 11x11), Performs Lee adaptive filtering on image data. The Lee Filter is primarily used on radar data to remove high frequency noise (speckle) while preserving high frequency features (edges). Median Filter (up to 7x7) Performs MEDIAN filtering on image data. The median filter smooths image data, while preserving sharp edges. Mode Filter (up to 7x7) Performs MODE filtering on image data. The Mode filter is primarily used to clean up thematic maps for presentation purposes. Programmable Filter (up to 33x33), Performs programmable filtering on image data. The programmable filter averages image data according to user specified weights. Prewitt Edge Filter (3x3), Performs PREWITT EDGE DETECTOR filtering for Image data. The Prewitt edge detector filter creates an image where edges (sharp changes in grey-level values) are shown. Sharpening Filter (up to 33x33) Performs an edge sharpening filter on image data. This filter improves the detail and contrast within an image. Sobel Edge Filter (up to 3x3), Performs SOBEL EDGE DETECTOR filtering for Image data. The Sobel edge detector filter creates an image where edges (sharp changes in grey-level values) are shown. SAR Speckle Filters Applies a speckle filter on a SAR image. The supported filters are: Lee Filter, Kuan Filter, Frost Filter, Enhanced Lee Filter, Enhanced Frost Filter, Gamma MAP Filter and Touzi Filter. These filters are primarily used on radar data to remove high frequency noise (speckle), while preserving high frequency features (edges). For convenience, a Block Average Filter and a Standard Deviation Filter are also provided. Lineament Extraction Extracts linear features from an image and records the polylines in a vector segment. This program is designed for extracting lineaments from radar images. However, it can also be used on optical images to extract curve-linear features. Sieve Filter (Class Merging) Reads an image channel, and merges image value polygons smaller than a user specified threshold with the largest neighbouring polygon. This is typically used to filter small classification polygons from a classification result. Modelling environment (can be used instead of EASI)
Atmospheric Correction / Biosphere parameter modelling: ATCOR0 ATCOR1 ATCOR2 ATCOR3 ATCOR2_T ATCOR3_T LAI SAVI FPAR (obsolete v.6) (obsolete v.6) Atmosheric correction for flat areas, calculates an atmospheric correction for flat areas applying constant or varying atmosphere. Atmospheric correction and topographic normalisation, calculates a ground reflectance image using elevation data. Calculation of surface temperature for flat area Calculation of surface temperature using elevation data Leaf Area Index model, calculates an Leaf Area Index model value. Soil Adjust Vegetation Index, calculates a Soil Adjusted Vegetation Index (SAVI) Fraction of Absorbed Photosynthetically Active Radiation, calculates fraction of Absorbed Photosynthetically Active Radiation Ratios, Indices, IHS, PCA: RTR ARI CHDET PCA DECORR (after PCA) IHS RGB FUSE FUSEPCT FUSION Image rationing Image arithmetics Principal Component Analysis (RGB to IHS Conversion) Converts red, green, and blue (RGB) image channels to intensity, hue, and saturation (IHS) image channels. The IHS program is the inverse of the RGB program. The Intensity-Hue-Saturation transformation is used by the FUSE and FUSEPCT procedures to perform data fusion. (IHS to RGB Conversion) Converts intensity, hue, and saturation (IHS) image channels to red, green, and blue (RGB) image channels. (FUSE - data fusion for RGB colour image performs data fusion of a Red-Green-Blue colour image with a black-and-white intensity image. The result is an output RGB colour image with the same resolution as the original B/W intensity image, but where the colour (hue and saturation) is derived from the resampled input RGB image. FUSE is an EASI procedure which uses the REGPRO, IHS, and RGB programs to perform data fusion. Data fusion for pseudocolour, performs data fusion of a pseudocolour image with a black-and-white intensity image. The result is an output RGB colour image with the same resolution as the original B/W intensity image, but where the colour (hue and saturation) is derived from the resampled input pseudocolour image. FUSEPCT is an EASI procedure which uses the REGPRO, PCE, IHS and RGB programs to perform data fusion. Data fusion of two input images, creates an output RGB colour image by fusing an input RGB colour or pseudocolour image with an input black-and-white intensity image, using the IHS transform (cylinder or hexcone model) or the Brovey transform.
