請問一下~ 我有參考前輩們的做法使用8連通的connected component 如下:     

void __fastcall TForm5::ComConnect(Graphics::TBitmap* BMP,int x,int y)
{
  BMP->Canvas->Pixels[x][y]=clBlack;
  Image4->Canvas->Pixels[x][y]=clYellow;      if(BMP->Canvas->Pixels[x+1][y]==clWhite)
    ComConnect(BMP,x+1,y);      if(BMP->Canvas->Pixels[x+1][y+1]==clWhite)
    ComConnect(BMP,x+1,y+1);      if(BMP->Canvas->Pixels[x][y+1]==clWhite)
    ComConnect(BMP,x,y+1);      if(BMP->Canvas->Pixels[x-1][y+1]==clWhite)
    ComConnect(BMP,x-1,y+1);      if(BMP->Canvas->Pixels[x-1][y]==clWhite)
    ComConnect(BMP,x-1,y);      if(BMP->Canvas->Pixels[x-1][y-1]==clWhite)
    ComConnect(BMP,x-1,y-1);      if(BMP->Canvas->Pixels[x][y-1]==clWhite)
    ComConnect(BMP,x,y-1);      if(BMP->Canvas->Pixels[x+1][y-1]==clWhite)
    ComConnect(BMP,x,y-1);
}    //---------------------------------------------------------------------------        void __fastcall TForm5::detection1Click(TObject *Sender)
{
 int ObjCount=0;
 Graphics::TBitmap *Bmp = new Graphics::TBitmap();
 Byte *ptr;
 Bmp->Assign(Image4->Picture->Bitmap );
 for(int y = 0; y < Bmp->Height; y++)
   {
      ptr = (Byte *) Bmp->ScanLine[y];
      for(int x = 0; x < Bmp->Width; x++)
      {
         if(ptr[x*3] == 255)
         {
            ComConnect(Bmp, x, y);
            
            ObjCount++;   //遞迴完就累積加一
            break;
         }
      }
   }
   ShowMessage("物件個數為"+IntToStr(ObjCount)+"個");
   delete Bmp;    }    

如果跑下面這張圖的話,那10個元件是可以搜尋到的 (因為我是做膚色區域給他二值化,所以做完二值化後,那10個元件都會是白色) 可是如果跑下面這張圖的話,就會跑出"stack overflow"的錯誤顯示 請問是為麼呢?該如何解決 謝謝 發表人 - lincher 於 2005/11/01 19:33:21
