imagery commands:
i.cca | Canonical components analysis (cca) program for image processing. |
i.class | 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 | |
i.gensig | Generates statistics for i.maxlik from raster map layer. |
i.gensigset | Generate statistics for i.smap from raster map layer. |
i.group | An imagery function that creates and edits groups and subgroups of imagery files. The interactive version provides extended functionality. |
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 | |
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 | |
i.ortho.photo | 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 | An imagery function that performs contextual image classification using sequential maximum a posteriori (SMAP) estimation. |
i.spectral | |
i.target | This program targets an imagery group to a GRASS location and mapset |
i.tasscap | |
i.vpoints | i.vpoints |
i.zc | Zero-crossing "edge detection" raster function for image processing. |
