Terrafrom QGIS plugin contains implementation of 11 popular topographic correction algorithms. Besides it the plugin provides an ability to evaluate the results of the correction algorithms by several methods: correlation between luminance and image digital numbers, rose-diagrams analysis and multi-criteria statistical analysis. Also, the plugin is capable of ranking topographic correction algorithms according to their applicability to a particular image using multi-criteria score based on the statistical metrics. Terraform plugin has processing provider, so you can easily combine the algorithm described above with other processing algorithms.
