findcontours opencv
當我們做物件辨識時，透過輪廓可得到特定物件的資訊，協助我們做判斷，OpenCV的findContours()函式可找到影像的輪廓，依實際需求調整參數輸入，而這邊的輪廓和Sobel這些找邊緣的處理不同，Sobel是將物件內部消除，只保留物件邊緣，findContours是在經過Sobel處理之後，將這個只有邊緣的影像，把各個邊緣 ...,... void* ) Mat canny_output; vector<vector<Point> > contours; vector<Vec4i> hierarchy; /// Detect edges using canny Canny( src_gray, canny_output, thresh, thresh*2, 3 ); /// Find contours findContours( canny_output, contours, hierarchy
