Ecway Technologies provides software development and IEEE projects from offices located in multiple cities across India. Their hybrid multiview stereo algorithm allows for 3D modeling of urban scenes using a combination of meshes and geometric primitives. It first segments an initial mesh-based surface using a multilabel Markov Random Field model. It then simultaneously samples primitive and mesh components on the obtained partition using a Jump-Diffusion process. The algorithm refines the hybrid representation iteratively to provide an increasingly accurate model of complex urban structures and large scenes.
