'Highgui can not be resolved'，JavaCV，Eclipse

Question

我試圖用JavaCV設置人臉檢測。我有cvLoadImage但當我嘗試通過Highgui.imread加載圖像時出現錯誤：'Highgui無法解析'和'Highgui'具有紅色波浪下劃線。由於某些原因，Eclipse無法正確處理導入的com.googlecode.javacv.cpp.opencv_highgui或...？

問題就在這裏：

CvMat myImg = Highgui.imread(myFileName);

任何幫助將不勝感激。

Answer 1

Mat m = Highgui.imread（myFileName）;來自builtin opencv java wrappers，而不是來自javacv（這是一個獨立的第三方包裝器）。

不幸的是，兩個併發apis都非常不兼容，因爲javacv正在包裝過時的c-api，而opencv正在包裝更現代的C++ api。
