Mr. Azimi-sadjadi et al., Temporal updating scheme for probabilistic neural network with applicationto satellite cloud classification - Further results, IEEE NEURAL, 12(5), 2001, pp. 1196-1203
A novel temporal updating approach for probabilistic neural network (PNN) c
lassifiers was developed [1] to account for temporal changes of spectral an
d temperature features of clouds in the visible and infrared (IR) GOES 8 (G
eostationary Operational Environmental Satellite) imagery data. In this bri
ef paper, a new method referred to as moving singular value decomposition (
MSVD) is introduced to improve the classification rate of the boundary bloc
ks or blocks containing cloud types with nonuniform texture. The MSVD metho
d is then incorporated into the temporal updating scheme and its effectiven
ess is demonstrated on several sequences of GOES 8 cloud imagery data. Thes
e results indicate that the incorporation of the new MSVD improves the over
all performance of the temporal updating process by almost 10%.
