Scope Summary: Admissible Events

Table 1 summarizes the capabilities of the algorithms to handle events. The first column indicates the capability to operate without the prior knowledge of the initial correspondences, called self-initialization. The options `Occlusion', 'Exit' and `Entry' refer to the corresponding events. In the table, `$+$' denotes the presence, `$-$' the absence of an option, while `$\pm$' means a limited capability.
