Towards efficient simulation of marked point process models for boat extraction from high resolution optical remotely sensed images

Abstract : Marked point processes have proven their efficiency in solving object extraction problems from high resolution optical images. However, these complex mathematical models are difficult to simulate which usually results in high computation times. A new parallel sampler has been recently developed. Nevertheless, this sampler does not yield good results in the presence of large objects. We propose modifications to the original parallel sampler to cope with such situations. Furthermore, we implement an additional mask to increase the speedup in the case of boat extraction.
