Comparing samples from the 0 distribution using a geodesic distance

Mostrar todas las versiones(2)

"The 0 distribution is widely used for monopolarized SAR image modeling because it can characterize regions with different degrees of texture accurately. It is indexed by three parameters: the number of looks (which can be estimated for the whole image), a scale parameter and a texture parame...
