Suponiendo que los datos han pasado ya todo tipo de correcciones de tipo geométrico o atmosférico, existen dos métodos complementarios para afrontar el problema de la generación de clases, estos son válidos tanto en imágenes de satélite como en cualquier otro campo: No establecer ninguna clase a priori, aunque es necesario determinar el número de clases que queremos establecer, y dejar que las defina un procedimiento automático (clasificación no supervisada). 1, record 1, Spanish, - clasificaci%C3%B3n%20no%20supervisada

Two supervised classification methodologies have been tested on a single full-polarimetric scene for the area; the maximum likelihood method using the amplitude at the standard linear polarizations(X-VV, C-HH,-HV,-VV and L-HH,-HV, VV) and the maximum contrast method which uses the complex covariance matrices at C-and L-band. 2, record 2, English, - polarimetric%20scene

Lorsque l'onde radar atteint une surface et en est diffusée, la polarisation peut être modifiée, tout dépendant des propriétés de la surface. Cette transformation modifie l'apparence de la scène polarimétrique, ce qui permet souvent de déterminer le type de surface à partir de l'image. 1, record 2, French, - sc%C3%A8ne%20polarim%C3%A9trique
