請教各位前輩~ 如果我有一張圖如下     做完connected-compoent之後可以找出那12個物件 如圖下(找出的物件以黃色顯示) 請問我該如何計算出每一個物件中的pixel值呢? 謝謝... 程式碼如下~~乃參考前輩們的程式碼..

-------------------//副程式//-------------------------------------    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);        }    //---------------------------------------------------------------------------    ----------------------------//主程式//-------------------------------    void __fastcall TForm5::detection1Click(TObject *Sender)
{     int num=0;
 int *A= new int[num];
 ZeroMemory(A,sizeof(int)*num);
 //動態宣告陣列
 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);
            num++;
         }
      }
   }
   ShowMessage("物件個數為"+IntToStr(num)+"個");
   delete Bmp;
   delete [] A;    }

您好: 若非必要,請使用JPEG的圖檔,且不需要那麼大張吧 <>< face="Verdana, Arial, Helvetica">引言:請問我該如何計算出每一個物件中的pixel值呢?

在ComConnect()遞迴過程中的
BMP->Canvas->Pixels就可以取得像素值了該物件的像素值了

順心
