class documentation

Class that stores the results of a segmentation evaluation.

Parameters
samples	the `fiftyone.core.collections.SampleCollection` used
config	the `SegmentationEvaluationConfig` used
eval_key	the evaluation key
pixel_confusion_matrix	a pixel value confusion matrix
classes	a list of class labels corresponding to the confusion matrix
matches	a list of `(gt_label, pred_label, pixel_count, gt_id, pred_id)` matches
missing	a missing (background) class
custom_metrics	an optional dict of custom metrics
backend	a `SegmentationEvaluation` backend

Instance Variable	`pixel_confusion_matrix`	Undocumented
Class Method	`_from_dict`	Subclass implementation of `from_dict`.
Static Method	`_parse_confusion_matrix`	Undocumented

Method	`confusion_matrix`	Generates a confusion matrix for the results via `sklearn:sklearn.metrics.confusion_matrix`.
Method	`metrics`	Computes classification metrics for the results, including accuracy, precision, recall, and F-beta score.
Method	`plot_confusion_matrix`	Plots a confusion matrix for the evaluation results.
Method	`print_metrics`	Prints the metrics computed via `metrics`.
Method	`print_report`	Prints a classification report for the results via `sklearn:sklearn.metrics.classification_report`.
Method	`report`	Generates a classification report for the results via `sklearn:sklearn.metrics.classification_report`.
