Imagery commands
Da GfossWiki.
| i.cca | Canonical components analysis (cca) program for image processing. |
| i.class | |
| i.cluster | An imagery function that generates spectral signatures for land cover types in an image using a clustering algorithm. The resulting signature file is used as input for i.maxlik, to generate an unsupervised image classification. |
| i.fft | Fast Fourier Transform (FFT) for image processing. |
| i.fusion.brovey | Brovey transform to merge multispectral and high-res panchromatic channels |
| i.gensig | Generates statistics for i.maxlik from raster map layer. |
| i.gensigset | Generate statistics for i.smap from raster map layer. |
| i.group | Crea ed edita gruppi e sotto gruppi di file immagini. |
| i.his.rgb | Hue-intensity-saturation (his) to red-green-blue (rgb) raster map color transformation function. |
| i.ifft | Inverse Fast Fourier Transform (ifft) for image processing. |
| i.image.mosaic | Mosaics up to 4 images and extends colormap; creates map *.mosaic |
| i.maxlik | An imagery function that classifies the cell spectral reflectances in imagery data based on the spectral signature information generated by either i.cluster, i.class, or i.gensig. |
| i.oif | Calculates Optimum-Index-Factor table for LANDSAT TM bands 1-5, & 7 |
| i.ortho.photo | |
| i.pca | Principal components analysis (pca) program for image processing. |
| i.points | |
| i.rectify | Rectifies an image by computing a coordinate transformation for each pixel in the image based on the control points |
| i.rgb.his | Red-green-blue (rgb) to hue-intensity-saturation (his) raster map color transformation function. |
| i.smap | Performs contextual image classification using sequential maximum a posteriori (SMAP) estimation. |
| i.spectral | displays spectral response at user specified locations in images |
| i.target | Targets an imagery group to a GRASS location and mapset. |
| i.tasscap | Tasseled Cap (Kauth Thomas) transformation for LANDSAT-TM data |
| i.vpoints | |
| i.zc | Zero-crossing "edge detection" raster function for image processing. |
