DetectionMethodofFabricDefecBasedonWaveletEntropy.
- 在采用二维离散小波变换对织物图像进行分解的基础上,引入了熵的概念,将小波熵作为织物图像的特征值,把熵值看作系统紊乱程度的度量,由此得到织物图像的小波熵特征值,通过与正常织物经过二维小波变换后提取的小波熵值相比较,熵值大者即认为有疵点存在-At the use of two-dimensional discrete wavelet transform decomposition of the fabric image, based on the introduction of the concep

- 目前擴增實境技術相關應用大部分以使用標記為主,但各式應用需求與日俱增,無標記(markerless)擴增實境技術使用上更具彈性,不必受限於標記的使用,因此應用層面更廣。視覺追蹤技術是擴增實境系統重要底層核心技術之一,但使用視覺追蹤技術在實際應用上易受到追蹤物件本身及外觀變化之影響,因此本文提出適用於無標記擴增實境應用之物件追蹤方法,能有效追蹤各式真實物件。首先框選設定追蹤物件;接著擷取物件特徵值,藉由特徵值比對以持續追蹤物件,並利用金字塔L-K光流法以縮短比對運算時間;最後經由2D-3D座標轉換
