Seafloor segmentation using multi-band SAS: initial results

An Initial Assessment of Effects of Seafloor Roughness on Coherent Sound Reflection from the Seafloor

A roughened seafloor may be expected to scatter incident sound at non-specular angles, but also to reflect coherently at the specular angle, with some loss of amplitude attributed to the scattering and some loss attributed to sound transmission into, and absorption within, the seafloor. Our initial expectation was that a reasonable estimation of the total coherent reflection loss, at a given gr...

A fast algorithm for MDL-based multi-band image segmentation

We consider the problem of image segmentation and describe an algorithm that is based on the Minimum Description Length (MDL) principle, is fast, is applicable to multi-band images, and guarantees closed regions. We construct an objective €unction that, when minimized, yields a partitioning of the image into regions where the pixel values in each band of each region are described by a polynomia...

Complexity Results for SAS+ Planning

We have previously reported a number of tractable planning problems deened in the SAS + formalism. This report complements these results by providing a complete map over the complexity of SAS + planning under all combinations of the previously considered restrictions. We analyze the complexity both of nding a minimal plan and of nding any plan. In contrast to other complexity surveys of plannin...

Multi-criteria logistics distribution network design using SAS/OR

This paper explores the use of the optimization procedures in SAS/OR software with application to the contemporary logistics distribution network design using an integrated multiple criteria decision making approach. Unlike the traditional optimization techniques, the proposed approach, combining analytic hierarchy process (AHP) and goal programming (GP), considers both quantitative and qualita...
