  • brightness : 白度
  1. In addition, on the basis of rgb - ihs and principle component analysis, this paper carries out a multi - spectral image merge experiment of cbers - 01 with aster, tm and spot, then makes a comparison on cbers - 01 and tm from the information of brightness, texture and edge, and macro characteristics

    基於rgb - ihs變換和主成分變換模式,將cbers - 01與aster 、 tm 、 spot等數據進行多光譜影像融合實驗。另外,展開cbers - 01與tm在灰度信息、紋理信息、邊緣信息及宏觀特點等方面的對比研究。
  2. Owning to the erasing effect, the correlation spots have not the same brightness if the holograms were exposed with the same times while recording. the correlation spot that related to the late recorded hologram is brighter than that related to the previous one. this problem can be solved by a subsequence exposure technique using in holograms receding

    本論文的研究發現,由於后記錄全息圖的寫入光束對先存全息圖的擦除效應,如果採用等時曝光法記錄幾百至上千幅全息圖,那麼相關點亮度將會變得均勻不一,后存比先存全息圖的相關點總體上要亮,而採用順序曝光法來記錄全息圖,就可以消除由擦除效應帶來的相關點亮度不均勻的問題。
