Cross entropy can measure the difference between the original image and its segmentation result. Compared with Shannon cross entropy, Tsallis cross entropy, in which a parameter q is introduced, provides flexibility and universality for the segmentation of image threshold. The asymmetric Tsallis cross entropy has more concise expression form. Therefore, a method of threshold selection is proposed based on the two-dimensional asymmetric Tsallis cross entropy using bee colony optimization. Firstly, the asymmetric Tsallis cross entropy is introduced and the threshold selection formulae based on the two-dimensional asymmetric Tsallis cross entropy are derived. Recursive algorithms are used to calculate the intermediate variables involved in criterion function for threshold selection and a lookup table is built to eliminate the redundant operations. The optimal two-dimensional threshold is searched by the bee colony algorithm. A large number of experiment results showed that the proposed method is greatly improved in terms of subjective visual effect and inter-regional contrast evaluation indicators compared to the relevant methods, such as the two-dimensional maximum Shannon entropy method, the two-dimensional Shannon cross entropy method, the two-dimensional Tsallis entropy method, and the two-dimensional symmetrical Tsallis cross entropy method. It can segment objects more accurately and has a faster running speed.
