HSIColorTransfer&PhaseEffect

彩色影像處理WhiteBalanceWhiteBalance白平衡目的物體在不同光源的照射下，顏色就會不同。比如同樣是一張白紙，在大太陽、日光燈、電燈泡底下，因色溫的不同就會呈現不同的顏色。白平衡簡單的說，就是讓白的拍出來像白的。

LED光源打光時因色溫會偏藍，因此可針對打勻均光源時做白平衡，將紅、綠顏色做補償。現階段已應用於擷取電路板全圖的光源上(MapLight)。WhiteBalance白平衡目的白平衡－比較白平衡－比較HSI彩色模型Hue，色度代表顏色的種類。Saturation，飽和度代表顏色中含有白色成分的多寡，即顏色的純淨程度，也就是白色中混入其它種顏色的比例。Intensity，亮度代表從黑到白之亮度變化。指色彩所引起人類對明暗程度的感覺。

HSI彩色模型Hue，色度HSIColorTransfer目的透過RGB彩色模型轉換到HSI彩色模型，由色調(H)、飽和度(S)、及亮度(I)的調整來強化出人眼想看到的影像結果。
