Reflection Filtering Options for Ghost Planes

The unpredictable nature of reflections and interreflections can create what are called ghost planes. Zivid has made filtering algorithms for the new SDK version 2.7 that can identify when these ghost planes occur and remove them. For small thin objects, like thin pipes, wires, and container edges, the company uses a local filter. For the high reflections and extremely shiny areas, there is a global filter. The global filter setting removes ghost planes very effectively, but if thin wires are present, it will probably remove them also. The local filter setting is gentler and whilst still removing most ghost planes in each situation, it is designed to preserve any thin wires that are present in the scene.
