Accuracy assessment – Remote Sensing - Open Library …
With many validation data points, a method is required to summarize all this information, and in remote sensing the method that is used universally, and has been for decades, is called the confusion matrix (also called ‘error matrix’ or ‘contingency table’).
Status of land cover classification accuracy assessment
2002年4月1日 · The confusion matrix lies at the core of much work on accuracy assessment and is frequently used without question to its suitability. The confusion matrix is used to provide a site-specific assessment of the correspondence between …
Accuracy Assessment: Quantifying Classification Quality
2023年10月2日 · The confusion matrix (also called the “error matrix”) (Stehman 1997) summarizes key accuracy metrics used to assess products derived from remotely sensed data.
Spatial analysis of remote sensing image classification accuracy
2012年12月1日 · This research demonstrates that data collected as part of a standard remote sensing validation exercise can be used to estimate mapped, spatial distributions of accuracy that would augment standard accuracy measures reported in the error matrix.
Confusion matrix of the supervised classification image
To test its accuracy, we develop an 18-year remote sensing analysis (2000–2018) of marabou dynamics using the Valle de los Ingenios, a Cuban UNESCO World Heritage Site, as an experimental model.

Accuracy Assessment - an overview | ScienceDirect Topics
Accuracy assessment is a crucial step in any remote sensing–based classification exercise, given that classification maps always contain misclassified pixels and, thus, classification errors. The impact of these errors depends on many factors, including. the complexity of the classification scheme and the separability of the underlying classes.
A generalized confusion matrix for assessing area estimates …
2010年11月25日 · An error matrix, derived from the generalized confusion matrix, allows the accuracy of maps generated using area estimation models to be assessed quantitatively and compared to the accuracies obtained from traditional classification techniques.
Some procedures have well-known quality dimension metrics like Root Mean Square Error (RMSE) or confusion/error matrix, etc. Yet numerous techniques flourish without any information on the level of trust of their outcomes.
Proper comparison among methods using a confusion matrix
Proper comparison among methods using a confusion matrix Abstract: An important aspect of research in the remote sensing field is to objectively compare different classifiers. This is the foundation of hundreds of research projects and in this paper we will address some raising concerns when evaluating solutions for classification of data sets ...
