OTB.ComputeConfusionMatrix: Computes the confusion matrix of a classification

This application computes the confusion matrix of a classification map relative to a ground truth dataset. This ground truth can be given as a raster or a vector data. Only reference and produced pixels with values different from NoData are handled in the calculation of the confusion matrix. The confusion matrix is organized the following way: rows = reference labels, columns = produced labels. In the header of the output file, the reference and produced class labels are ordered according to the rows/columns of the confusion matrix.

Inputs

The input classification image.

format
href
Please set a value for in.

Choice of the output format as a contingency table for unsupervised algorithmsor confusion matrix for supervised ones.

string
Please set a value for format.

Choice of ground truth format

string
Please set a value for ref.

Input image containing the ground truth labels

format
href
Please set a value for ref.raster.in.

Label to be treated as no data in ref raster.

integer

Input vector data of the ground truth

format
href
Please set a value for ref.vector.in.

Field name containing the label values

string
Please set a value for ref.vector.field.

Label to be treated as no data in ref vector. Please note that this value is always used in vector mode, to generate default values. Please set it to a value that does not correspond to a class label.

integer

Label to be treated as no data in input image

integer

Available memory for processing (in MB)
