很抱歉是同一題,不過本來的題目它掛點了
所以我在PO一次

各位前輩
最近用影像處理在擷取紅色目標物的圖
並且加上標籤
不過在同一塊的紅色圖上
卻會出現不同數目的標籤
如圖所示


下面會附上我標籤化的程式
請問各位前輩
這樣的問題會是出在哪裡?
該怎麼解決呢?

謝謝



[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
