Web在OpenCV中,漫水填充算法由floodFill函数实现,其作用是用我们指定的颜色从种子点开始填充一个连接域,连通性由像素值的接近程度来衡量。在OpenCV中,有两个C++重写版本的floodFill,函数声明如下: floodFill(image, mask, seedPoint, newVal[, loDiff[, upDiff[, flags]]]) … WebIn OpenCV, the cv.threshold function is used, but pass the string Otsu instead of the threshold value. Then the algorithm finds the optimal threshold value and returns it as the second output. If Otsu thresholding is not used, this value is same as the threshold value you used. Check out below example. Input image is a noisy image.
