圖片處理好幫手

我們在做圖像伸縮處理的時候會發現直線變彎臉部變形等等現象，這是因為一般的圖片伸縮完全是按照點來縮放，下麵這個軟件則是分析圖像的邏輯關係，能夠根據圖像中的景物伸縮切割保持勻稱的效果，甚至可以固定一邊收縮另一邊，從demo看來真是天衣無縫。

Spot this pretty amazing new resizing technique from Dr Ariel Shamir and Shai Avidan of the Efi Arazi School of Computer Science. Revealed SIGGRAPH this new method of image resizing looks for seams (not simple columns or rows) of pixels with the 'least energy' (least contrast / change in detail) both vertically and horizontally in the image and then uses this to enable resizing without losing important image content such as human subjects or other detail. This technique can be used for reducing and enlarging images as well as removing items from the image which are not wanted (by manually painting 'negative weight' over an area of the image). But less of my waffle just jump in and watch this video of the algorithm in use, I assure you it will make considerably more sense.
