各位前輩
最近再利用影像處理去擷取紅色的目標物
是用YUV來擷取
不過遇到一個問題
就是我將紅色區塊標示標籤
不過像附檔的圖一樣
明明是同一區塊的紅色
卻出現了三個標籤值
請問前輩這會是哪裡出了問題嗎??

附上標籤化的程式如下
[code cpp]
int Label=1;
// 標籤Frame初始化
for(int Row=0;Row for(int Col=0;Col ColorBufOrgn_Labeling[Row][Col] = 0;
}
}
// 標籤法演算法(3*3)
// 尋找方向如下：
// →→→
// ↑ ↓
// ←← ↓
for(int Row=1;Row for(int Col=1;Col if(ColorBufOrgn[Row][Col][2] == 255){
// 周圍如果也是紅色，且有非零的標籤值，就將標籤值給中間的
if((ColorBufOrgn[Row-1][Col-1][2] == 255)&&(ColorBufOrgn_Labeling[Row-1][Col-1] != 0))
{ColorBufOrgn_Labeling[Row][Col] = ColorBufOrgn_Labeling[Row-1][Col-1];}
else if((ColorBufOrgn[Row-1][Col][2] == 255)&&(ColorBufOrgn_Labeling[Row-1][Col] != 0))
{ColorBufOrgn_Labeling[Row][Col] = ColorBufOrgn_Labeling[Row-1][Col];}
else if((ColorBufOrgn[Row-1][Col 1][2] == 255)&&(ColorBufOrgn_Labeling[Row-1][Col 1] != 0))
{ColorBufOrgn_Labeling[Row][Col] = ColorBufOrgn_Labeling[Row-1][Col 1];}
else if((ColorBufOrgn[Row][Col 1][2] == 255)&&(ColorBufOrgn_Labeling[Row][Col 1] != 0))
{ColorBufOrgn_Labeling[Row][Col] = ColorBufOrgn_Labeling[Row][Col 1];}
else if((ColorBufOrgn[Row 1][Col 1][2] == 255)&&(ColorBufOrgn_Labeling[Row 1][Col 1] != 0))
{ColorBufOrgn_Labeling[Row][Col] = ColorBufOrgn_Labeling[Row 1][Col 1];}
else if((ColorBufOrgn[Row 1][Col][2] == 255)&&(ColorBufOrgn_Labeling[Row 1][Col] != 0))
{ColorBufOrgn_Labeling[Row][Col] = ColorBufOrgn_Labeling[Row 1][Col];}
else if((ColorBufOrgn[Row 1][Col-1][2] == 255)&&(ColorBufOrgn_Labeling[Row 1][Col-1] != 0))
{ColorBufOrgn_Labeling[Row][Col] = ColorBufOrgn_Labeling[Row 1][Col-1];}
else if((ColorBufOrgn[Row][Col-1][2] == 255)&&(ColorBufOrgn_Labeling[Row][Col-1] != 0))
{ColorBufOrgn_Labeling[Row][Col] = ColorBufOrgn_Labeling[Row][Col-1];}
// 唯一能更改標籤的地方
else{ColorBufOrgn_Labeling[Row][Col] = Label; Label ;}

}
}
}
//這裡進行再過濾，防止誤判
//透過這個，可以確保一整個區塊的標籤都是同樣的
for(int Row=1;Row
for(int Col=1;Col // 如果MASK內全部都有標籤
if( (ColorBufOrgn_Labeling[Row-1][Col-1] != 0)&&(ColorBufOrgn_Labeling[Row][Col-1] != 0)&&(ColorBufOrgn_Labeling[Row 1][Col-1] != 0)&&
(ColorBufOrgn_Labeling[Row-1][Col ] != 0)&&(ColorBufOrgn_Labeling[Row][Col ] != 0)&&(ColorBufOrgn_Labeling[Row 1][Col ] != 0)&&
