摘要

In this paper, improvement on man-computer interactive classification of clouds based on bispectral satellite imagery has been synthesized by using the maximum likelihood automatic clustering(MLAC)and the unit feature classification(UFSC)approaches. The improved classification not only shortens the time of sample-training in UFSC method, but also eliminates the inevitable shortcoming of the MLAC method.(e.g., 1, sample selecting and training is confined only to one cloud image; 2. the result of clustering is pretty sensitive to the selection of initial cluster center; 3. the actual classification basically can not satisfy the supposition of normal distribution required by MLAC method; 4. errors in classification are difficult to e modified.).
