PCA,NA-PCA,MAF,ICA methods are available. It is also possible to compute the inverse transform to reconstruct the image. It is also possible to optionnaly export the transformation matrix to a text file.<h2>Parameters</h2><ul><li><b>[param] -in</b> <string> The input image to apply dimensionality reduction.. Mandatory: True. Default Value: ""</li><li><b>[param] -out</b> <string> output image. Components are ordered by decreasing eigenvalues.. Mandatory: True. Default Value: ""</li><li><b>[param] -rescale</b> <string> . Mandatory: False. Default Value: "0"</li><li><b>[param] -outinv</b> <string> reconstruct output image.. Mandatory: False. Default Value: ""</li><li><b>[param] -nbcomp</b> <int32> Number of relevant components kept. By default all components are kept.. Mandatory: False. Default Value: "0"</li><li><b>[param] -normalize</b> <boolean> center AND reduce data before Dimensionality reduction.. Mandatory: False. Default Value: "True"</li><li><b>[param] -outmatrix</b> <string> Filename to store the transformation matrix (csv format). Mandatory: False. Default Value: ""</li><li><b>[param] -inxml</b> <string> Load otb application from xml file. Mandatory: False. Default Value: ""</li><li><b>[param] -outxml</b> <string> Save otb application to xml file. Mandatory: False. Default Value: ""</li><b>[choice] -method</b> Selection of the reduction dimension method. pca,napca,maf,ica. Mandatory: True. Default Value: "pca"<ul><li><b>[group] -pca</b></li><ul></ul><li><b>[group] -napca</b></li><ul><li><b>[param] -method.napca.radiusx</b> <int32> . Mandatory: True.
