Summary: Given a sequence of tasks \(\mathcal {T}\) subject to precedence constraints between adjacent tasks, and given a set of fixed intervals \(\mathcal {I}\), the TaskIntersection \((\mathcal {T},\mathcal {I},o, inter )\) constraint restricts the overall intersection of the tasks of \(\mathcal {T}\) with the fixed intervals of \(\mathcal {I}\) to be greater than or equal \((o= ` \geq ')\) or less than or equal \((o= ` \leq ')\) to a given limit \( inter \). We provide a bound \((\mathbb {Z})\)-consistent cost filtering algorithm wrt the starts and the ends of the tasks for the TaskIntersection constraint and evaluate the constraint on the video summarisation problem.
