The Classification and Pattern Recognition toolset contains tools for performing classification and regression analysis workflows, including accuracy assessment.
Classifies a raster dataset based on an Esri classifier definition file (.ecd) and raster dataset inputs.
The .ecd file contains all the information needed to perform a specific type of Esri-supported classification. The inputs to this tool must match the inputs used to generate the required .ecd file.
Computes a confusion matrix with errors of omission and commission and derives a kappa index of agreement, Intersection over Union (IoU), and an overall accuracy between the classified map and the reference data.
Computes a set of attributes associated with the segmented image. The input raster can be a single-band or 3-band, 8-bit segmented image.
Creates randomly sampled points for post-classification accuracy assessment.
Generates training samples from seed points, such as accuracy assessment points or training sample points. A typical use case is generating training samples from an existing source, such as a thematic raster or a feature class.
Estimates the accuracy of individual training samples. The cross validation accuracy is computed using the previously generated classification training result in an .ecd file and the training samples. Outputs include a raster dataset containing the misclassified class values and a training sample dataset with the accuracy score for each training sample.
Performs subpixel classification and calculates the fractional abundance of different land cover types for individual pixels.
Predicts data values using the output from the Train Random Trees Regression Model tool.
Corrects segments or objects cut by tile boundaries during the segmentation process performed as a raster function. This tool is helpful for some regional processes, such as image segmentation, that have inconsistencies near image tile boundaries.
This processing step is included in the Segment Mean Shift tool; it should only be used on a segmented image that was not created from that tool.
Groups into segments adjacent pixels that have similar spectral characteristics.
Generates an Esri classifier definition file (.ecd) using the Iso Cluster classification definition.
Generates an Esri classifier definition file (.ecd) using the K-Nearest Neighbor classification method.
Generates an Esri classifier definition file (.ecd) using the Maximum Likelihood Classifier (MLC) classification definition.
Generates an Esri classifier definition file (.ecd) using the Random Trees classification method.
Models the relationship between explanatory variables and a target dataset using random trees analysis.
Generates an Esri classifier definition file (.ecd) using the Support Vector Machine (SVM) classification definition.
Updates the Target field in the attribute table to compare reference points to the classified image.
