Generation of error matrix

The error matrix, also known as the confusion matrix or contingency table, is a fundamental tool in the evaluation of classification accuracy in remote sensing and image analysis. It quantifies the agreement between classified results and reference data by comparing observed class assignments with ground truth information. Here's an overview of the steps involved in generating an error matrix:
