VF2++ – a subgraph isomophism algorithm for molecular pattern matching


In a previous blog entry, we introduced COIN-OR::LEMON (http://lemon.cs.elte.hu), the open source C++ graph and network modelling library. As we mentioned there, this library targets both academic and industrial applications. In this post a use-case for the latter is shown.   Last year, QuantumBio Inc.1 approached us with a simple request: they were using LEMON […]

Image Analysis for Particle Tracking in Wood Cutting Processes

Path lines of the particles using optical flow.

Austria is a key player in the forestry and wood industry. Separating or cutting of wood is one of the most important process steps resulting in huge amounts of particles of different sizes (chips, dust). The rapid removal of particles from the process zone and from the processing space is thus of great importance (surface quality, […]
