Graph-based deformable 3d object matching

WebJul 1, 2024 · In this article, we’ll see how to use Generalized Hough Transform with OpenCV to do shape based matching. This algorithm takes points along the contours of an object with the help of Canny filter. Then, for each point, the gradient orientation is calculated from two Sobel filters, one horizontal and one vertical.

WebA deformable mesh wraps around a point cloud and iteratively learns its internal features to reconstruct a 3d object with more detail. The initial mesh is a coarse approximation of the point cloud. If the object has a genus of zero, we use the convex hull of the point cloud for the approximation. This is used as input to a CNN that predicts ... spectral signature of lily https://e-profitcenter.com
