Multicategory recoginition is very important to practicality of remotely-sensed image classification。This paper has presented a mixed classification methodintegrating multi-layer neuron network and unsupervised classification algorithm

Atthe first step

a multi-layer neuron network is used and the result serves as inputfor the unsupervised classification at the second step.The number of patterns thatcan be recognized is increased from 10 to 30.Applying this algorithm to SPOTremotely-sensed image recognition shows it can adapt the requiry of multicategoryrecognition.
