隨著現在科技的進步，交友軟體也越來越多，所以照片給人的第一印象是非常重要的，大部分的交友軟體，如果想要吸引人的注目，往往照片的呈現就決定了成敗。目前市面上販售的數位相機或是智慧型手機上的APP軟體都具有美肌的功能，但普遍的做法都是直接淡化整張照片讓顯眼的痘疤消失，而這樣的做法只能針對較小的痘疤有效，並無法移除較大面積的痘疤或是傷疤。因此，我們這篇論文主要的貢獻就是使用者可以自行的更換膚色，再更換膚色的同時就可以達到除疤的效果。

為了要讓膚色多元化，於是我們利用網路搜尋各種明星的膚色來建立我們的膚色資料庫。除了使用者可以自行更換喜愛的膚色外，我們也有自動配對膚色的功能，可以從我們的資料庫中選出一組與使用者輸入的照片最相近的膚色套用上去。讓使用者能保有原本的膚色樣貌，而不會有太大的差異，從我們的實驗結果中，我們成功的將臉上的疤痕完全去掉，並且提供使用者能夠自由的更換膚色，讓原本的樣貌有了各種不同的效果。

This paper presents a novel system to remove facial scars and pores for a portrait. The facial skin complexion and colors are important attractive factors, and most people consider that a good portrait should be scar free and have smooth facial colors.

Currently, most available commercial digital cameras or smart phones all provide facial-skin-beatification functions, but most of them only use simple image processing functions to smooth the taken image for the removal of small-scale unwanted facial scars and pores and these functions cannot remove large and obvious scars or pores from the face.

Therefore, the main contribution of this system allows the user to replace the facial skin of a portrait with a beautiful and scar-less skin of another portrait chosen from a collected database which consists of scar-less and beautiful faces from webs.
