WebSep 21, 2024 · I will start by stating that I'm slowly going insane. I am trying to extract contours from an image and compute their centers of mass using Java and OpenCV. For all the inner contours, the results are correct, however for the outer (largest) contour, the centroid is way, way off. The input image, the code and the output result are all below.
WebMar 31, 2024 · The x coordinate of the centroid is given by A candidate for F is then F (x,y,z) = (1/2 x^2, 0, 0) as ∇ . F = x. Things work similarly but not our function is non-linear, so the calculation for the integral of each triangle will be more complex. We can use Barycentric coordinate system to make the integral over the triangle easier.

We use a DFS to calculate the size of each subtree ( x is the root). Then, we can “walk” to the centroid starting from x by: If x is the centroid, return x. Else, we know that exist exactly one node y adjacent to x satisfying y > n 2. Walk to y and do it again. healthie company
