appearing distance
解釋
燈光初顯距離-
The angular distance between the sun and a planet or the moon. it is also the difference in ecliptic longitude between the sun and other celestial objects. when an inferior planet follows the sun in its daily motion, appearing east of the sun in the evening, it is in eastern elongation
距角是太陽和太陽系內天體的角距，亦即是太陽和它們相差的黃經，以在日落後見于西方的內行星來說，這時內行星在處于太陽的東面，若這時的角距是在這段時間內最大的，便是 -
By using subarea - subsection mining method, multi - channel layout program, heidaigou open - pit coal mine has overcomed the technological continuity problems appearing in bench combination and has fully improved the capacity of existing equipments, so that the transportation distance has been reduced and enormous economic benefits have been gained
在此過程中，黑岱溝露天煤礦通過分區分段開采、多通道布置等方案，克服了並段臺階工藝接續過程中出現的問題，最大限度的增加現有設備生產能力，減少運距，創造了巨大的經濟效益。 -
A few small nondescript stars were appearing elsewhere. iii the distance a dog barked, and wheels occasionally rattled along the dry road
遠處有一隻狗在叫，偶爾也聽見車輪在乾燥的路面上嘎吱嘎吱地碾過。 -
First classifier chooses two classes whose matching distance between it and paper currency is bigger than others from all class. then in the second stage, we extract some new feature and improve the classifier to generate the last result. in the stage of defect detection for paper currency, we advances a homogeneity based algorithm for the detection of scratch and cracks appearing on paper currency, in which the homogeneity feature of the sensed paper currency image is first constructed to locate the pixels that probably been polluted, the image registration algorithm is subsequently used to overlay the sensed and reference paper currency image
在特徵提取中，我們對基於方向塊的特徵提取方法進行了分析，在此基礎上針對美元特點，對圖像方向塊的劃分方式做了研究，並提出了基於幾何距離的特徵提取方法;在分類器設計中，我們採用了lvq網路對紙幣進行學習與分類，並提出了一種具有兩層結構的分類演算法，第一層首先對輸入的特徵向量進行粗分類，選定與特徵向量匹配距離最大的兩類幣種，進入第二層分類器;在第二層分類器中，我們通過研究進入該模塊兩類幣種特徵塊的相關性，重新設計了特徵向量，同時對分類器進行改進，最終實現對紙幣的分類。
