| dc.description.abstract (摘要) | 傳統對地圖的註記標示皆採人工方式，相當耗費時間且不經濟，對地名等註記亦多採用黑色，如此，在黑白影像地圖中較黑暗之部分，難以清楚顯現註記符號，對彩色影像地圖而言，黑色註記又常與地物影像混淆視覺。本文即針對此部份做一研究，期能以電腦輔助完成明確、清晰的註記標示。 當一物質在某波段中強烈反射及放射能量，相對於另物質在同波段中呈現低的反射及放射量，將產生高反差對比，同時也使影像判釋較為容易。本研究依據此特性，嘗試以電腦輔助方式，使影像與註記標示產生適當的反差對比，如此不論影像色調如何，皆能明確且清楚的展現註記標示。 | - |
| dc.description.abstract (摘要) | Labeling on map usually given manually in the past. it required a great deal of time and was not efficient in terms of cost. Also, the labels are often marked in black, which did not show up very well in the black and white images where the tone was very dark. These issues are therefore, focused on in the next paragraphs and hopefully, with the aid of computers, labels on image map could have clear appearance. When an object strongly reflects and radiates energy at a certain band, at the same time there is one that barely reflects and releases energy. Thus, a high contrast is resolved. This will make the maps easier to read. The research will base this character, and try to make the labeling computerized. This will result in a more appropriate contrast on both the views and labels. Thus, the labels will he seen more clearly interpretable despite their brightness value. | - |
