WebJan 8, 2013 · Contours can be explained simply as a curve joining all the continuous points (along the boundary), having same color or intensity. The contours are a useful tool for shape analysis and object detection and recognition. For better accuracy, use binary images. So before finding contours, apply threshold or canny edge detection. WebDuality is a fascinating concept. The way you get new properties from an algorithm by merely swapping planes and points is, in a way, a mathematical miracle. Conclusion In practice, marching cubes and dual contouring tend to be complicated because we want more than just a contour or a triangle mesh out of them.
