女神一秒變路人 騰訊研發'一鍵卸妝'功能大綱

As virtual makeup apps gain popularity, Chinese developers are working on a way to remove makeup from over-edited photos.

隨着虛擬化妝應用越來越流行，我國開發者正在研究爲過度編輯的照片卸妝的途徑。

Tencent Youtu Lab, an artificial intelligence research lab under tech giant Tencent, released a new algorithm that can reverse over-edited deceiving pictures.

科技巨頭騰訊旗下的人工智能研究實驗室騰訊優圖實驗室發佈了一種可以將過度編輯、有欺騙性的圖片復原的新算法。

Dubbed "makeup-go," the algorithm is claimed to be the first of its kind in the world, and it focuses on tackling the two issues of skin smoothing and skin color change.

這種名爲“一鍵卸妝”的算法，聲稱是世界上首個該類型的算法，主要解決磨皮和皮膚調色這兩個問題。

One of the difficulties mentioned by the lab is that every virtual makeup software performs quite differently, which make it impossible to learn all operations that can smooth skin, suppress wrinkle and freckle, and adjust tone.

實驗室提及的困難之一是，每一款虛擬化妝軟件的運行不盡相同，使其不可能學會磨皮、平皺、祛斑和調色的所有操作。

Therefore, the team designed a new algorithm to reverse pictures "blindly."

因此，該團隊設計了一種新算法來“盲復原”圖片。

Also, instead of directly regressing the pictures towards the unedited version, the network regresses levels of principal components of the edited parts separately. As a result, subtle detail information won't be ignored.

另外，該系統並不是直接將照片轉化爲未經編輯的版本，而是分步驟分層次將每個編輯部分逐個還原。這樣，那些細微的細節就不會被忽略了。

Makeup-go doesn't handle geometric face-lifting at the moment, the team said in the paper.

該團隊在文件中寫道，這個軟件目前還無法處理面部整容問題。
