不過經過測試發現Boost library似乎不支援/CLR,
這個等之後有空再繼續研究,
目前打算改採由C#掃描某個資料夾下所有的Txt檔案,
並堆疊至一個string型態變數, 每個檔案路徑以分號( ; )區隔,
然後C#傳入該string給C++ DLL進行解析, 並儲存至一個txt檔案,
以便觀察是否正確….

void ImgProc::loadTxtToMat(wchar_t* fileListPath, wchar_t* fileName)

wstring savefileName(fileName);
fout.open(savefileName, std::ios_base::out);
wstring ws(fileListPath);
string fileList = ImgProc::WstringToString(ws);
char *s = new char[fileList.length() + 1];
strcpy(s, fileList.c_str());
char *t = strtok(s, ";");
while (t != NULL) {fout << t << endl;
t = strtok(NULL, ";");}
fout.close();
delete[]s;}

測試
接下來, 準備讀入一張一張影像路徑(*.txt)讀入暫時的Mat資料格式
並計算全部影像N張的平均和標準差
以下為單一張影像I 的平均和標準差公式
