是看PCLEADER介紹的,它說這套軟體可以把小圖變成大圖,我沒時間試啦,不曉得兩位大大有沒有用過,效果真的有那麼神嗎?

他跟一般的補點方式的不同在於它可以將整張圖裡Sharp和Smooth部份給分開以不同的補點方式去補點,如他的內容所說的吧:
S-Spline on the other hand "looks" at the image in an intelligent way, and tries to adapt its patented interpolation method from pixel to pixel, depending on how sharp or smooth the image is in that area. For smooth areas, the algorithm will perform much like B-Spline or Bicubic interpolation .For sharp areas it uses different interpolation techniques and some mathematical tricks , trying to maintain the original sharpness of the image.

After enlarging an image with Bicubic interpolation, the sharp parts in the original image will become blurred just like the smooth parts, so it's not possible for such algorithms to distinguish which parts need more "fixing" than others.

S-Spline does both, automatically.<-----S-Spline可以自動幹這檔子事,所以也沒有多神.基本上還是很死,因為如何判斷Sharp跟Smooth就很主觀了.不過如果一點都不好用就不會拿出來賣了....畢竟懶人還是很多(我就是其中之一):D :D
