Open dataset

Save dataset : save results (no pipeline module created)

Extract ROI from dataset : extract ROI for pipeline computation

Save dataset (advanced) : save with choice of output format, channels,

etc.

Cache dataset : execute previous pipelines elements and cache results

Concatenate images : concatenate several images

Geometry

Orthorectification

Reproject image : reprojection of ortho-images

Superimpose two images

Homologous points extraction : manual selection of homologous points,

then re-sampling of the image on the fixed one.

GCP to Sensor Model : manual set of longitude / latitude of

geographical points, then re-sample of the image.

Menu Geometry > Reproject image

Reproject the image (existence of geometric model) into another

ground reference


19

orfeo-toolbox.org

Menu Geometry > Superimpose two images

Combination of geometric models of the two images (note : works with

images with geometric model)

➢ Image to be superimposed : use of the direct geometric model to

build Longitude/Latitude projection

➢Combination with the inverse model of the reference image.

➢Reprojection

Filtering


➢More than 65 features !

Mean, variance, Gradient, spectral angleTextures (energy, entropy, contrast, etc)

Morphological filters

Radiometric indexes• Vegetation (NDVI, ARVI, etc), Soil, Built up, Water

Edge density

Mean shiftOriginal data (=> no need to concatenate channels after filtering)

Etc

➢Use before SVM classification for example

Pan-sharpen an image

➢Requires Panchromatic and Multispectral input images at the same

resolution
