摘要：
A facial symmetry detection method includes a detecting step and a determining step, wherein the detecting step includes a pre-processing step, a feature extracting step and a feature selecting step. The pre-processing step captures an image by an image capture device, and pre-processes the image so as to produce a post-processing image. The feature extracting step extracts a plurality of image features from the post-processing image so as to produce an image feature set. The image feature set includes a plurality of feature symmetry indexes and a plurality of blocking similarities. The feature selecting step selects a part of image feature from the image feature set so as to produce a determining feature set and enter the determining feature set into a classifier. The determining step produces a determining result according to the determining feature set. The determining result is divided into an unsymmetrical state and a normal state. Therefore, an accuracy rate of the facial symmetry detection method and a system thereof are increased.一種臉部對稱性檢測方法包含偵測步驟及判斷步驟，偵測步驟包含前處理步驟、特徵提取步驟及特徵選取步驟。前處理步驟透過影像擷取裝置擷取影像資料並針對影像資料進行前處理以得到處理後影像。特徵提取步驟針對處理後影像進行特徵提取以產生影像特徵集合，影像特徵集合包含複數特徵對稱性指數及複數特徵區塊相似度。特徵選取步驟針對影像特徵集合進行特徵選取以形成判斷特徵集合，並將判斷特徵集合輸入至分類器。判斷步驟為分類器根據判斷特徵集合以產生判斷結果，判斷結果為不對稱狀態或正常狀態。藉此，可提升檢測方法及其系統的準確度。
