《MFC使用OpenCV造成記憶體洩漏問題》

問題描述
新建一個MFC應用程式，匯入OpenCV，只要使用了OpenCV裡面的東西（假設定義了一個Mat變數），當程式在執行時，不會有任何反應，但是當點選應用程式右上角的叉叉關閉程式時，那麼問題就來了，輸出視窗會出現一大堆記憶體洩漏問題，這是假記憶體洩漏，如下圖所示：
Detected memory leaks! Dumping objects -> {680} normal block at 0x01147EB0, 56 bytes long. Data: <@ > 40 04 E9 0F 00 00 00 00 00 00 00 00 CD CD CD CD {679} normal block at 0x01147AE8, 908 bytes long.

解決方法
1、找到當前專案的解決方案資源管理器，選擇專案名稱，點選滑鼠右鍵，選擇最底下的屬性選項。
2、點選屬性選項之後，進入屬性頁面，依次找到配置屬性、連結器、輸入、延遲載入的DLL選項，然後去把OpenCV的bin檔案下的所有dll的名稱新增到延遲載入的DLL中，新增完之後，點選確定，然後再執行一下程式，基本上就沒有記憶體洩漏出現了。
3、我把所有dll貼上來，用的是OpenCV2410的，有需要的自己改下
opencv_contrib2410.dll opencv_core2410.dll opencv_features2d2410.dll opencv_flann2410.dll opencv_gpu2410.dll opencv_highgui2410.dll opencv_imgproc2410.dll opencv_legacy2410.dll opencv_ml2410.dll opencv_nonfree2410.dll opencv_objdetect2410.dll opencv_ocl2410.dll opencv_photo2410.dll opencv_stitching2410.dll opencv_superres2410.dll opencv_ts2410.dll opencv_video2410.dll opencv_videostab2410.dll opencv_contrib2410d.dll opencv_core2410d.dll opencv_features2d2410d.dll opencv_flann2410d.dll opencv_gpu2410d.dll opencv_highgui2410d.dll opencv_imgproc2410d.dll opencv_legacy2410d.dll opencv_ml2410d.dll opencv_nonfree2410d.dll opencv_objdetect2410d.dll opencv_ocl2410d.dll opencv_photo2410d.dll opencv_stitching2410d.dll opencv_superres2410d.dll opencv_ts2410d.dll opencv_video2410d.dll opencv_videostab2410d.dll
