OpenCv 尋找凸包convexHull
凸包 convex hull 是乙個計算幾何 圖形學 中的概念,在乙個實數向量空間v中,對於給定集合x,所有包含x的凸集的交集s被稱為x的凸包。x的凸包可以用x內所有點 x1,x2 xn 的線性組合來構造。在二維歐幾里得空間中,凸包可以想象為一條剛好包著所有點的橡皮圈,用不嚴謹的話來講,給定二維平面...
OpenCV學習筆記(十五)之凸包

ACM 尋找凸包
尋找凸包 點集q的凸包ch q 是乙個最小的凸多邊形p,它滿足q中的每個點或者在p的邊界上,或者在p的內部。現對於給定的點集q,求q的凸包ch q 的頂點集合。輸入 輸入有若干組測試資料。每一組測試資料的第一行上有整數n,表示該組測試資料有n個點組成的。接下來有n行,其每一行上有二個正整數,之間用乙...
