Clustered-Dot Halftoning With Direct Binary Search. Goyal, P., Gupta, M., Staelin, C., Fischer, M., Shacham, O., & Allebach, J. Image Processing, IEEE Transactions on, 22(2):473-487, 2013.

In this paper, we present a new algorithm for aperiodic clustered-dot halftoning based on direct binary search (DBS). The DBS optimization framework has been modified for designing clustered-dot texture, by using filters with different sizes in the initialization and update steps of the algorithm. Following an intuitive explanation of how the clustered-dot texture results from this modified framework, we derive a closed-form cost metric which, when minimized, equivalently generates stochastic clustered-dot texture. An analysis of the cost metric and its influence on the texture quality is presented, which is followed by a modification to the cost metric to reduce computational cost and to make it more suitable for screen design.
