This paper sketched out the concept of the Honeycomb Marker Fields - a highly deformable and occlusion-tolerant marker field. We focused on the design of the Y-junctions, the visual image features which appear between the modules (cells) of the marker field. As the main contribution, we presented an algorithm for real-time and robust detection of the Y-junctions, and its experimental evaluation. The specialized Y-junction detection algorithm outperforms a general interest point detector (FAST) in the detection performance. The measurements thus lead to conclusion that for applications which can accept a marker field as a fiduciary pattern, the reliability and performance can be significantly improved. Based on the presented detector of Y-junctions and the preliminary HMF detector, we plan for the closest future to construct a robust and fast detector of the marker field and showcase it on selected applications. Thanks to the performance of the Y-junction detector, the algorithm is expected to be functional on today's ultramobile devices. The next step thus will be to implement it for some of the popular smartphone platforms.
