WebJan 8, 2013 · The Subdiv2D class described in this section is used to perform various planar subdivision on a set of 2D points (represented as vector of Point2f). OpenCV subdivides a plane into triangles using the Delaunay's algorithm, which corresponds to the dual graph of the Voronoi diagram. In the figure below, the Delaunay's triangulation is marked with ... WebJul 28, 2024 · ESPCN (Efficient Sub-Pixel CNN), proposed by Shi, 2016 is a model that reconstructs a high-resolution version of an image given a low-resolution version. It leverages efficient "sub-pixel convolution" layers, which learns an array of image upscaling filters. In this code example, we will implement the model from the paper and train it on a ...
