singular values
解釋
奇異值-

The identification rate of the former could be above 90 %, whereas the later is below 80 %. for three kinds of targets involving sand, grit and sullage, the feature of singular values excels that of invariant moment, the identification of the former could be to 92 %, whereas the later is 84 %. analyzing the features this dissertation extracts, we can find that the features of rock and sullage are more similar, so do pebble and grit, and the features of sand are obviously distinguished
分類結果發現，對于以上五類目標，利用直方圖有關參數作為分類特徵比奇異值特徵有效，前者效果可達90以上，而後者低於80 ；對于沙、砂礫、淤泥三類目標而言，奇異值特徵比不變矩特徵更為有效，前者效果可達92以上，而後者為84 ；從本文中抽取的特徵如直方圖的參數以及奇異值來看，巖石與淤泥的特徵比較接近，而卵石與砂礫的特徵比較接近，沙的特徵則與其他四類有明顯區別。 -
