Part 1 of this article introduced the technologies of the MIMEX project, focusing on the use of computer vision (CV). As mentioned there, CV allows MIMEX to recognize both people and objects without the need to add explicit, wearable/mobile tags. While this offers clear advantages, including ease of installation and use, by its nature, CV suffers from object occlusion (when objects are outside or hidden from the view of the cameras), poor lighting conditions (in which objects in the resulting images cannot be distinguished from one another) and cost (as one of the mitigation techniques for occlusion is to add multiple cameras, even in a small space).
